Lithium batterie has become ubiquitous in our lives. I believe that many people have encountered the situation of lithium batterie can not be charged. Here, we will tell you some common reasons why lithium batterie can not be charged and how to deal with them.
Poor connection of the battery charger: If the contact between the lithium batterie and the charger is poor, it will lead to the battery can not be charged. At this time, please check whether the contact between the battery and the charger plug is good, or replace the charger and battery to try.
Incorrect battery polarity: If the battery is reversed into the charger, it will also result in the battery not charging. We should connect the positive terminal of the battery to the positive terminal of the charger and the negative terminal of the battery to the negative terminal of the charger.
Faulty charger: A faulty charger will prevent the battery from charging. In this case, you need to replace the charger to solve the problem.
Battery aging: If the lithium ion battery has been used for a long time, the capacity of the battery may have been reduced, the internal resistance of the battery may increase, these will lead to the battery can not be fully charged. At this time you need to replace the battery with a new one.
Insufficient charging voltage: If the output voltage of the charger is insufficient, it will also lead to the battery can not be fully charged. At this time you need to check whether the output voltage of the charger meets the requirements of 18650 batteries pack.
In short, if the lithium battery can not be charged, we need to check the connection, polarity, charger, battery aging and many other factors, find the problem and repair or replace the device.

Many electric vehicles are powered by lithium batterie that rely on cobalt—a scarce, expensive metal with high environmental and social costs. A team of researchers from Japanese and French universities has now developed a practical nickel-based electrode material that opens new avenues to cobalt-free batteries for electric vehicles.
The researchers detailed their findings in a study published in the journal Energy Storage Materials.
“There is an undeniable need for cobalt-free, high-energy electrode materials for lithium batterie,” said Naoaki Yabuuchi from Yokohama National University.
Lithium batterie can be recharged when lithium ions flow from a positively charged electrode to a negatively charged electrode. In most lithium batterie for portable electronics, the positive electrode contains lithium cobalt oxide (LiCoO2), a chemical compound that offers high stability and energy density.
However, the limited, fraught supply chain of cobalt creates a bottleneck for large-scale batteries, including the ones used in electric vehicles. In addition, cobalt extraction generates toxic waste that contaminates land, air, and water.
To address these issues, lithium nickel oxide (LiNiO2)—which is similar in structure to LiCoO2—often serves as a cobalt-free alternative for electrode material. However, key instability issues plague the compound, specifically a gradual loss of capacity at the high-voltage region, which is associated with nickel-ion migration.
To improve electrode reversibility, nickel ions have been partially substituted by other metal ions, including reintroduced cobalt ions as well as manganese, aluminum and magnesium, to create “nickel-enriched layered materials” to serve as positive electrode materials.
“So far, 10–20 percent cobalt ions were necessary for nickel-based electrode materials,” Yabuuchi said. This, according to Yabuuchi, is still too much, and a unified understanding of how metal substitution can improve the process has not yet been established.
To address this knowledge gap, Yabuuchi and collaborators dug deeper into the problematic phase transition. When lithium ions leave the cathode under the influence of an external field, nickel ions migrate to specific sites within the lithium layers. Although this process is reversible, the reversibility gradually degrades through continuous cycles until the capacity is completely lost—a phenomenon not seen in cobalt-ion migration.
Previous studies reported that tungsten doping in LiNiO2 is an efficient approach to suppressing the detrimental phase transitions at high-voltage regions. Yabuuchi and collaborators tested the hypothesis that heavy, expensive tungsten ions could be substituted with other elements, specifically phosphorous—a lighter, more abundant element.
After detailed analysis on LiNiO2 integrated with nanosized lithium phosphate (Li3PO4), the researchers observed that, under certain conditions, problematic nickel-ion migration was effectively suppressed due to repulsive electrostatic interaction from the extra nickel ions within the Li layers.
Moreover, from these findings, Li-deficient LiNiO2, Li0.975Ni1.025O2, with the extra nickel ions in Li layers, is also synthesized using a simple methodology without phosphorus integration. Results also showed how Li0.975Ni1.025O2 can effectively mitigate unfavorable nickel-ion migration, and deliver consistent reversibility without cobalt ions.
“These findings open a new direction to develop high performance and practical cobalt-free nickel-based electrode materials with an extremely simple and cost-effective methodology,” Yabuuchi said. “This material achieved the ultimate goal for high-performance nickel-based electrode materials.”
In future endeavors, the researchers plan to investigate the feasibility of a nickel-free material to support lithium-ion batteries.

LiFePO4 batteries, or lithium iron phosphate batteries, offer several advantages over other types of batteries, such as high cycle life, enhanced safety, and lower self-discharge rates. However, they also come with some limitations, including cost and energy density constraints.
Advantages
High Cycle Life: LiFePO4 batteries demonstrate excellent cycle life, typically reaching thousands of charge-discharge cycles. This makes them an ideal choice for applications requiring long-term stability and durability, such as electric vehicles and energy storage systems.
Enhanced Safety: LiFePO4 batteries are relatively safe, with a lower risk of thermal runaway or explosions compared to other types of lithium-ion batteries. This is mainly due to their chemical stability and lower combustion temperature, making them suitable for applications demanding high levels of safety, like electric vehicles and home energy storage systems.
Lower Self-Discharge Rates: LiFePO4 batteries exhibit relatively low self-discharge rates, meaning they lose less charge during long-term storage or periods of non-use. This makes them more suitable for applications requiring extended storage or periodic use.
Limitations
Cost: The manufacturing cost of LiFePO4 batteries is typically higher compared to other types of lithium-ion batteries. While costs have been gradually decreasing with technological advancements and economies of scale, they may still limit competitiveness in certain applications.
Energy Density: LiFePO4 batteries have a relatively lower energy density, meaning they store less energy per unit volume or weight compared to other battery types. Therefore, in applications where high energy density is crucial, such as electric vehicles, other types of lithium-ion batteries may be preferred, despite potential trade-offs in safety and cycle life.
In summary, LiFePO4 batteries offer numerous advantages, particularly in safety and cycle life. However, factors such as cost and energy density need to be carefully considered when selecting battery types, balancing various requirements and constraints.

Compared to lithium batterie, Sodium-ion batteries still have a number of weaknesses that could be remedied by optimizing the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with scandium and magnesium.
The scientists collected data at the X-ray sources BESSY II, PETRA III, and SOLARIS to get a complete picture and uncovered two competing mechanisms that determine the stability of the cathodes. Their research is published in the journal Advanced Materials.
Lithium batterie have the highest possible energy density per kilogram, but lithium batterie resources are limited. Sodium, on the other hand, has a virtually unlimited supply and is the second-best option in terms of energy density. Sodium-ion batteries (SIBs) would therefore be a good alternative, especially if the weight of the batteries is not a major concern, for example in stationary energy storage systems.
However, experts are convinced that the capacity of these batteries could be significantly increased by a targeted material design of the cathodes. Cathode materials made of layered transition metal oxides with the elements nickel and manganese (NMO cathodes) are particularly promising.
They form host structures in which the sodium ions are stored during discharge and released again during charging. However, there is a risk of chemical reactions which may initially improve the capacity, but ultimately degrade the cathode material through local structural changes. This has the consequence of reducing the lifetime of the sodium-ion batteries.
“But we need high capacity with high stability,” says Dr. Katherine Mazzio, who is a member of the joint research group Operando Battery Analysis at HZB and the Humboldt-Universität zu Berlin, headed by Prof Philipp Adelhelm. Spearheaded by Ph.D. student Yongchun Li, they have now investigated how doping with foreign elements affects the NMO cathodes.
Different elements were selected as dopants that have similar ionic radii to nickel (Ni 2+), but different valence states: magnesium (Mg 2+) ions or scandium ions (Sc 3+).
Three years of experiments at BESSY II, PETRA III, and SOLARIS
To decipher the influence of the two elements, they had to carry out experiments at three different X-ray sources.
At BESSY II, they analyzed the samples using resonant inelastic X-ray scattering (RIXS) and X-ray absorption spectroscopy (XAS) in the soft and hard X-ray ranges; at PETRA III, they evaluated structural changes with X-ray diffraction (XRD) and pair distribution function analysis (PDF) with hard X-rays, and for more detailed insights on the element magnesium, they carried out additional soft XAS investigations at the PIRX beamline at SOLARIS.
“The results surprised us,” explains Mazzio. Although doping with scandium leads to fewer structural changes during the electrochemical cycle than doping with magnesium, it does not improve stability. “Until now, it was thought that suppressing phase transitions (and thus volume changes) would also improve the cathode material cycling performance over many cycles. But that’s not enough.”
Magnesium doping suppresses the oxygen redox reaction in NMO even more. This was also unexpected, as magnesium is known to trigger an oxygen redox reaction in layered manganese oxides. “We analyzed different Mg/Ni ratios in NMO and found that the oxygen redox reaction reaches a minimum at a ratio close to 1,” explains Mazzio.
“Only through a combination of advanced X-ray techniques could we show that it is more than just suppression phase transitions that are important for improving the long-term cycling behavior, but also the interplay between Ni and O redox activity dictate performance.”

LiFePO4 batteries have garnered significant attention in recent years due to their impressive cycle life and charge/discharge performance. As a leading energy storage solution, understanding the intricacies of LiFePO4 batteries is essential for businesses and individuals alike.
What are LiFePO4 Batteries?
LiFePO4 batteries, or lithium iron phosphate batteries, belong to the family of lithium-ion batteries renowned for their stability, high energy density, and long cycle life. Unlike conventional lithium-ion batteries, LiFePO4 batteries offer improved safety and thermal stability, making them ideal for a wide range of applications, including electric vehicles, renewable energy storage, and portable electronics.
What are the factors that affect the cycle life of LiFePO4 batteries?
Depth of Discharge (DoD)
The cycle life of LiFePO4 battery is closely tied to the depth of charge and discharge cycles. Generally, shallower discharge depths extend battery lifespan. It’s recommended to maintain discharge depths between 20% and 80% to balance performance and cycle life.
Charging Voltage and Rate
Excessive charging voltage or rate can induce stress within the battery, leading to reduced cycle life. Strict control over charging voltage and rate can prolong battery lifespan.
Temperature Management
LiFePO4 batteries may experience decreased performance at lower temperatures, while high temperatures accelerate battery aging. Therefore, effective temperature management is crucial for extending battery lifespan.
Frequency of Charge/Discharge Cycles
Frequent charge/discharge cycles can accelerate battery aging. Minimizing frequent charge/discharge cycles can extend battery lifespan.
How to maximize the lifespan of LiFePO4 batteries？
Control Depth of Discharge (DoD): The depth to which a battery is discharged during each cycle significantly impacts its overall lifespan. Avoid fully charging or discharging LiFePO4 batteries. It’s recommended to keep the depth of discharge between 20% and 80%. Deep discharge accelerates battery aging, so limiting the DoD helps extend battery life.
Avoid Overcharging: Control charging voltage and rate rigorously to prevent overcharging. Excessive charging voltage can lead to electrolyte decomposition and internal stress, reducing battery lifespan.
Effective Temperature Management: Ensure LiFePO4 batteries operate within the appropriate temperature range. High temperatures accelerate battery aging, while low temperatures reduce battery performance. Avoid exposing batteries to extreme temperature conditions and take measures to maintain optimal operating temperatures.
Minimize Frequent Charge/Discharge Cycles: Reduce unnecessary charge/discharge cycles as frequent cycling accelerates battery aging. Minimizing these cycles helps prolong battery life.
Utilize Advanced Battery Management Systems (BMS): Implement BMS to monitor battery status and adjust charging/discharging processes accordingly. This optimization maximizes battery performance and lifespan.
Avoid Vibration and Mechanical Stress: Vibrations and mechanical stress can damage LiFePO4 battery internals, leading to performance degradation. Minimize exposure to severe vibrations during installation and use.
Regular Maintenance and Inspection: Perform regular inspections and maintenance on LiFePO4 batteries. Ensure connectors and wiring are in good condition, clean battery surfaces, and check for any abnormalities. Regular maintenance allows for early detection and resolution of issues, prolonging battery lifespan.
In summary, through prudent control of charge/discharge cycles, temperature management, and the use of battery management systems, LiFePO4 battery lifespan can be maximized while optimizing charge/discharge performance.

AGM replacement battery/marine battery/lithium batterie/battery replacement/Energy storage battery/ LiFePO4 battery bank are widely used in our daily life. And in some areas, like North America, North Europe, the temperature in winter is always lower than 32°F (0°C). How can they use the battery properly in winter, such as charging and discharging, below 32°F (0°C)? This is a practical problem that customers will meet.
As we know, conventional lithium-ion batteries or LiFePO4 battery cannot be charged at temperature below 32°F (0°C).
Gladly, the heating film can help to solve this problem. When the temperature is below 32°F (0°C), the heating film will be turned on under charging conditions. During heating , the charger only supplies power for the heating film and it will not charge the battery. When battery heats up to 50°F (10°C), the BMS stops heating and the battery starts to charge. When storaging and discharging, the heating film neither works nor consumes battery power.
Currently, our 12V 100Ah/25.6V 100Ah/51.2V 100Ah LiFePO4 battery bank, or other AGM replacement battery can be equipped with a heating pad, which can help to solve the charging problem when temperature below 32°F (0°C).

A multi-institutional team of Chinese engineers has developed a proof-of-concept calcium-based battery that withstands 700 charge cycles at room temperature. In their paper published in the journal Nature, the group describes the challenges they addressed in developing the battery and what they have learned about the possible use of calcium-based batteries in consumer products in the future.
The current standard for rechargeable custom lithium battery pack used in consumer products is lithium. But because it is a rare material and has issues such as poor aging and the need to prevent overcharge, scientists have been looking for a suitable replacement. One such material is calcium, which is 2,500 times as abundant as lithium.
Prior research has suggested rechargeable batteries based on calcium should be possible if problems can be resolved. One of the biggest challenges is finding suitable electrolyte and electrode materials that can provide stability and safety.
In this new effort, the researchers attempted to develop a useable, rechargeable, calcium–oxygen-based battery—prior research has suggested such pairings are likely to have the highest energy density of calcium-based batteries. Prior efforts to create batteries using this approach have run into problems with inactive discharge materials, and it has also been challenging to find electrolytes that can work with both calcium and oxygen.
To overcome these problems, the team in China created a new type of liquid electrolyte that works with both calcium and oxygen. This involved the use of a two-electron redox process and specific proportions of materials. The result was a battery that could be charged and recharged up to 700 times at room temperature.
The research team also incorporated their battery into flexible fibers which they wove into a textile, presenting the possibility of wearable consumer products. They acknowledge that the battery is still not efficient enough for use in commercial products, but they plan to continue their work to see if it can be improved.
