In our technologically dependent society, the mobility, dependability, and safety of our devices—including phones and laptops—are critical. Just as important is our ability to easily charge and recharge these devices so they are available when we need them. To do this, we use rechargeable batteries, specifically lithium batterie.

They give us the freedom of movement and connectivity we need. As society’s needs evolve, so too does our tech, and so too must the batteries that allow us to use this tech. One of the most urgent concerns regarding lithium-ion batteries is their safety. Though rare, there are issues with explosions and fires caused by electrochemical system instability.

“Consequently, there is an urgent need to develop LIBs that can provide higher energy density, longer cycle life, and improved safety,” said Ying Bai, corresponding author of new research on this topic and a professor at the Beijing Institute of Technology in China.

Beijing scientists have been researching the use of additives in the sulfone-based electrolyte of  lithium batterie to improve their performance. They found that by adding triphenylphosphine oxide (TPPO), “the TPPO improves the thermal stability of the electrolyte, which has important industrial value and foundational significance of TPPO as an additive for advancing the development of LIB’s,” said Chuan Wu, co-corresponding author on the research and a professor at Beijing Institute of Technology.

The team’s paper is published in Energy Materials and Devices.

When lithium batterie is discharging lithium-ions, they move from an anode, which is an electrode where current enters the battery, through an electrolyte that passes through a separator to a cathode, which is where the current leaves the storage battery to energize a device. The path is reversed when recharging.

“In the composition of the battery, the non-aqueous electrolyte used in LIBs plays a crucial role in determining key performance parameters such as cycle life, power density, and efficiency,” said Ying Bai. Power density is a measure of stored power per volume, and cycle life is the number of charge/discharge cycles that a battery can undergo before it starts to decrease the percentage of charge it can hold.

The electrolyte solutions in use now have some issues with cycle stability, thermal stability, and safety. Rather than completely changing the electrolyte solution, the team chose to test the use of an additive, TPPO, in the electrolyte to improve the performance of the overall battery.

When tested, TPPO was found to have several important properties.

“Firstly, it reduces the flame point of the sulfone electrolyte; Secondly, it selectively forms a stable passivation film, enhancing the interface stability between the sulfone electrolyte and the electrode material,” said Chuan Wu. The passivation film forms as the TPPO decomposes and coats the cathode, rendering it more resistant to wear and tear, similarly reducing the electrolyte’s breakdown while enhancing the lithium ions’ movement across the electrolyte.

Using theoretical calculations, electrochemical characterization, and flammability tests, the researchers found “that the addition of 2 wt.% TPPO to the sulfone-based electrolyte significantly enhances the ionic conductivity within the temperature range of 20–60°C.”

“Additionally, it increases the discharge capacity of LIBs in the range of 2–4.8 V while maintaining excellent rate performance and cycling stability. Flammability tests and thermal gravimetric analysis (TGA) results indicate the excellent non-flammability and thermal stability of the electrolyte,” said Ying Bai.

In short, the new electrolyte that they have developed is safer as it is non-flammable, is thermally stable and has an increased energy discharge capacity.

We know that lithium batterie. But a NIMS research team has developed a new technique to image grain boundaries obstructing lithium-ion migration in solid-state batteries—a promising type of next-generation battery.

Solid-state batteries—next-generation rechargeable batteries—are intended to be safer and have higher energy densities than conventional lithium batterie by replacing liquid organic electrolytes with solid electrolytes. A major issue in current solid-state battery R&D is the obstruction of lithium-ion migration at the interfaces between active materials and solid electrolytes and at the grain boundaries within solid electrolytes.

These obstructions lower charge/discharge rates and reduce energy density in batteries. A solid electrolyte is composed of crystalline grains and the boundaries between them. Existing ionic conductivity evaluation methods had only been able to measure average ionic conductivity across a solid electrolyte and were unable to quantify ionic conductivity at individual grain boundaries and identify boundaries restricting ionic migration.

This research team succeeded in imaging and quantifying ionic migration/diffusion at individual grain boundaries within a solid electrolyte using secondary ion mass spectrometry (SIMS). SIMS enables the imaging of chemical element distribution across a solid electrolyte specimen by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions.

Li-ion-lithium batterie

The team first replaced a portion of a stable lithium isotope, 7Li (mass number: 7, natural abundance: 92%), constituting an electrolyte specimen with another lithium isotope, 6Li (mass number: 6, natural abundance: 8%), at the edge of the specimen using an isotope exchange technique.

The team then observed the diffusion of 6Li within the specimen using SIMS. Because it was impossible to image and quantify the distribution of fast-diffusing 6Li using conventional SIMS, the team significantly slowed 6Li diffusion by cooling the specimen (i.e., cryo-SIMS), enabling the team to precisely measure the 6Li distribution and identify grain boundaries acting as bottlenecks to ionic migration.

The cryo-SIMS technique can be used to directly observe lithium-ion diffusion, identify interfaces/grain boundaries acting as bottlenecks among the many interfaces/boundaries existing in a solid-state battery, and determine the causes of these obstructions. This approach is expected to contribute to the development of higher-performance solid-state batteries.

The work is published in the Journal of Materials Chemistry A.

A sodium battery developed by researchers at The University of Texas at Austin significantly reduces fire risks from the technology, while also relying on inexpensive, abundant materials to serve as its building blocks.

Though battery fires are rare, increased battery usage means these incidents are on the rise.

The secret ingredient to this sodium battery breakthrough, published recently in Nature Energy, is a solid diluent. The researchers used a salt-based solid diluent in the electrolyte, facilitating the charge-discharge cycle. A specific type of salt—sodium nitrate—allowed the researchers to deploy just a single, nonflammable solvent in the electrolyte, stabilizing the battery as a whole.

Over time, the multiple liquid solvents in an electrolyte—the component that transfers charge-carrying ions between the battery’s two electrodes—react with other components in ways that degrade batteries and lead to safety risks. Sodium, an alternative to lithium that is one of the key ingredients in this battery, is highly reactive, posing a significant challenge to the adoption of these types of batteries. These reactions can lead to the growth of needle-like filaments called dendrites that can cause the battery to electrically short and even catch fire or explode.

“Batteries catch fire because the liquid solvents in the electrolyte don’t get along with other parts of the battery,” said Arumugam Manthiram, a professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and the lead researcher on the project. “We have reduced that risk from the equation to create a safer, more stable battery.”

In addition to the safety improvement, this new, sodium-based battery represents a less expensive alternative to the lithium-ion batteries that power smartphones, laptops, electric cars and more.

Future Batteries(Article illustrations)-sodium battery

The battery also boasts strong performance. How long a battery lasts on a single charge tends to decline over time. The new sodium battery retained 80% of its capacity over 500 cycles, matching the standard of lithium-ion batteries in smartphones.

“Here we show a sodium battery that is safe and inexpensive to produce, without losing out on performance,” Manthiram said. “It is critical to develop alternatives to lithium-ion batteries that are not just on par with them, but better.”

Though the researchers applied this technique to a sodium battery, they said it could also translate to lithium-ion-based cells, albeit with different materials.

Lithium mining is expensive and has been criticized for its environmental impacts, including heavy groundwater use, soil and water pollution and carbon emissions. By comparison, sodium is available in the ocean, is cheaper and is more environmentally friendly.

Lithium-ion batteries typically also use cobalt, which is expensive and mined mostly in Africa’s Democratic Republic of the Congo, where it has significant impacts on human health and the environment. In 2020, Manthiram demonstrated a novel, cobalt-free lithium-ion battery.

This battery is also free of cobalt, as well as lithium. The other components are made of 40% iron, 30% manganese and 30% nickel.

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.

 

  1. 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.

 

  1. 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.

 

  1. Faulty charger: A faulty charger will prevent the battery from charging. In this case, you need to replace the charger to solve the problem.

Fast-charging-lithium batterie

  1. 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.

 

  1. 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.

1100mah 3.7v battery

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.

li-ion-14.8v-12ah-battery-lithium batterie

“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.

Himax 12V 120Ah LiFePO4 Battery Pack

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.
