The difference between Li-PO battery and metal casing lithium battery mainly refers to the material of the shell.
Polymer batteries are just liquid lithium-ion batteries with a polymer shell. Structurally, it is packaged with aluminum-plastic film. If a safety hazard occurs, the aluminum-plastic film of the battery will only inflate and crack at most.
The metal casing lithium-ion battery is made of steel or aluminum, and the cover assembly has an explosion-proof power-off function.
Compared with metal casing lithium ion batteries, polymer batteries have more or less advantages in terms of weight, capacity, shape, etc.
However, polymer batteries generally have smaller capacities and higher molding costs. The MOQ is high for customized battery, so the current market share of soft-pack lithium-ion batteries is relatively small.

Charge-recharge cycling of lithium-super-rich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
The energy capacity and charge-recharge cycling (cyclability) of lithium-iron-oxide, a cost-effective cathode material for rechargeable lithium-ion batteries, is improved by adding small amounts of abundant elements. The development, achieved by researchers at Hokkaido University, Tohoku University, and Nagoya Institute of Technology, is reported in the journal ACS Materials Letters.
Lithium ion batteries have become indispensable in modern life, used in a multitude of applications including mobile phones, electric vehicles, and large power storage systems.
A constant research effort is underway to increase their capacity, efficiency, and sustainability. A major challenge is to reduce the reliance on rare and expensive resources. One approach is to use more efficient and sustainable materials for the battery cathodes, where key electron exchange processes occur.
The researchers worked to improve the performance of cathodes based on a particular lithium-iron-oxide compound. In 2023, they reported a promising cathode material, Li5FeO4, that exhibits a high capacity using iron and oxygen redox reactions. However, its development encountered problems associated with the production of oxygen during charging-recharging cycling.
“We have now found that the cyclability could be significantly enhanced by doping small amounts of abundantly available elements such as aluminum, silicon, phosphorus, and sulfur into the cathode’s crystal structure,” says Associate Professor Hiroaki Kobayashi at the Department of Chemistry, Faculty of Science, Hokkaido University.
A crucial chemical aspect of the enhancement proved to be the formation of strong ‘covalent’ bonds between the dopant and oxygen atoms within the structure. These bonds hold atoms together when electrons are shared between the atoms, rather than the ‘ionic’ interaction between positive and negatively charged ions.
“The covalent bonding between the dopant and oxygen atoms makes the problematic release of oxygen less energetically favorable, and therefore less likely to occur,” says Kobayashi.
The researchers used X-ray absorption analysis and theoretical calculations to explore the fine details of changes in the structure of the cathode material caused by introducing different dopant elements. This allowed them to propose theoretical explanations for the improvements they observed. They also used electrochemical analysis to quantify the improvements in the cathode’s energy capacity, stability and the cycling between charging and discharging phases, showing an increase in capacity retention from 50% to 90%.
“We will continue to develop these new insights, hoping to make a significant contribution to the advances in battery technology that will be crucial if electric power is to widely replace fossil fuel use, as required by global efforts to combat climate change,” Kobayashi concludes.
The next phase of the research will include exploring the challenges and possibilities in scaling up the methods into technology ready for commercialization.

A green industrial future for Europe may depend on an element that is part of a household staple: table salt. Dr. John Abou-Rjeily, a researcher at Tiamat Energy in France, is using sodium to develop rechargeable batteries. Sodium is a part of sodium chloride, an ionic compound that is the technical name for ordinary salt.
The idea behind sodium-ion batteries is to reduce Europe’s reliance on the lithium-ion ones that power everything from toothbrushes and mobile phones to mopeds and cars.
Today’s batteries include materials such as lithium, nickel and cobalt that are both scarce and toxic, whereas sodium is one of the most plentiful elements on Earth.
“Sodium-ion batteries are based on more abundant and safer materials than lithium-ion batteries,” said Abou-Rjeily. “There’s not enough lithium ions and cobalt and nickel to meet everyone’s needs.”
He is a research and development engineer at Tiamat, which designs and manufactures sodium-ion batteries.
Abou-Rjeily led a research project to develop sodium-ion batteries that have commercial appeal and can serve as a new foundation for European manufacturing.
Called NAIMA, the project ran from December 2019 through May 2023. It featured companies, research institutions and universities in Bulgaria, Belgium, France, Germany, the Netherlands, Slovenia, Spain and Sweden.
Battery charge
Batteries are central to Europe’s drive to replace fossil fuels with renewable-energy sources such as wind and solar power. More clean energy in Europe requires new storage capacity that batteries can provide.
The European battery market could be worth as much as €250 billion a year as of 2025. Europe aims to increase its share of global battery-cell production to as high as 25% this decade from 3% in 2018, chipping away at Asia’s 85% dominance.
The research covers all segments of the supply chain—from access to raw materials needed to make batteries and the infrastructure required for storing energy to “smart grids” that automatically charge vehicles when power is cheapest and battery designs that ensure recycling.
Lithium-ion batteries can store lots of energy in a small space, making them winners for smart phones and electric cars. Sodium-ion batteries are slightly bigger and potentially cheaper, making them candidates for storing energy in places such as homes, power tools and small vehicles.
French connection
Abou-Rjeily, a trained chemist from Lebanon, moved to France in 2016 to pursue an interest in environmental sustainability.
He is at home with Tiamat, whose sodium-ion batteries exclude lithium, cobalt and copper and largely avoid nickel too. The company is a spinoff from the French National Center for Scientific Research, or CNRS, which was among the NAIMA participants.
Lithium, cobalt, copper and nickel are on an EU list of critical raw materials, highlighting concerns in Europe about reliance on foreign suppliers and supply squeezes.
For example, when it comes to lithium-ion batteries worldwide, China manufactured almost 80% of them in 2021.
Furthermore, most global production of lithium-ion batteries is expected to go to the automotive industry.
Tiamat plans in 2026 to open a gigafactory in the French city of Amiens to produce sodium-ion batteries suitable initially for equipment such as power tools, according to Abou-Rjeily.
He said NAIMA helped advance the company’s battery know-how.

The project also helped partners move forward with a type of sodium-ion battery for renewable-energy storage. This kind of battery could also one day be suitable for some cars.
While it wouldn’t ever challenge the 500-kilometer capacity of lithium-ion batteries, this sodium-ion type could be more competitive for smaller stretches, according to Abou-Rjeily.
“They could be cheaper for short and medium driving distances,” he said.
Home base
An energy link between cars and homes through sodium-ion batteries is a vision of Dr. Magdalena Graczyk-Zajac, a visiting professor at the Technical University Darmstadt in Germany.
Also an electrochemist at the German energy company EnBW, she is involved in a project to develop a sodium-ion battery for homes. Called SIMBA, the project is due to wrap up in June 2024 after three and a half years.
Graczyk-Zajac paints a future where energy captured by photovoltaic panels on homes is stored in a rechargeable household sodium-ion battery. The battery would then power the homes and charge the inhabitants’ electric vehicles.
Graczyk-Zajac said such a scenario would mean a big cut in transportation costs.
“You could be driving your car for free for eight to nine months of the year,” she said.
Household gains
While sodium-ion and lithium batteries work in a similar way, sodium is a larger ion than lithium. That’s one reason that a sodium-ion battery takes up a little more space.
For home storage, such a battery would be placed underground or in a garage, so a slightly larger battery wouldn’t matter much, according to Graczyk-Zajac.
SIMBA, which involves almost 20 research institutes, universities and companies from across Europe, has put together some essential components of a home sodium-ion battery for laboratory testing.
One part, the anode, is made from hard carbon, which can be manufactured from wood or biowaste. Another—the cathode—can be made of a material called Prussian white.
While lithium-ion cathodes frequently contain cobalt, this Prussian white cathode contains iron, which is a more abundant and cheaper metal.
This cathode was developed by Altris, a spinoff in 2017 from Uppsala University in Sweden—one of the SIMBA participants.
Altris made headlines in November 2023 when its industry partner, Sweden-based Northvolt, announced that it would make batteries in Europe with the cathode.
In general, sodium-ion batteries promise households in Europe the chance for cheaper and cleaner energy.
The batteries also offer the prospect of financial gains through the storage and then either sale of spare electricity to the grid when home production is higher than needed or later use in the home.
Graczyk-Zajac recommends the later-use option. “A householder would save more money by just keeping that energy,” she said.

Especially prevalent in applications where safety cannot be compromised, such as electric vehicles and renewable energy systems, LiFePO4 batteries offer an appealing alternative to traditional lithium-ion batteries. This article delves deeply into the safety features of LiFePO4 batteries, compares them with other battery types, and discusses how Himax Electronics utilizes this technology to deliver superior safety in battery solutions.
Understanding LiFePO4 Battery Safety
Chemical and Thermal Stability: LiFePO4 batteries are constructed using lithium iron phosphate as the cathode material, which inherently provides significant safety advantages. The phosphate chemistry grants these batteries a strong bond that withstands extreme abuse conditions better than other lithium chemistries. This chemical stability leads to superior thermal stability, meaning LiFePO4 batteries are less likely to suffer from thermal runaway—a condition where increased temperature causes a reaction that continuously increases temperature, leading to fires or explosions.
Overcharge and Overdischarge Resistance: One of the significant risks with battery technologies is the potential for overcharging or deep discharging, which can compromise battery integrity and safety. LiFePO4 batteries inherently resist both conditions. They maintain a stable voltage range during charging and discharging, which helps prevent the scenarios where voltage spikes or dips could lead to hazardous situations.
Comparative Safety with Other Battery Technologies
LiFePO4 vs. Lithium-Cobalt Oxide (LiCoO2): While LiCoO2 batteries, commonly used in mobile devices and laptops, store higher amounts of energy, they pose higher risks of thermal runaway and are more sensitive to high temperatures. In contrast, LiFePO4 batteries operate safely at higher temperatures and are significantly less prone to catastrophic failure when damaged.
LiFePO4 vs. Nickel-Metal Hydride (NiMH): NiMH batteries, found in many hybrid vehicles, are less volatile than traditional lithium-ion batteries but still lag behind LiFePO4 in terms of overall safety, lifespan, and weight efficiency. LiFePO4 batteries offer a lighter, more efficient solution with a considerably longer life cycle and better stability during thermal stress.

Lithium Iron Phosphate (LiFePO4) batteries have emerged as a leading choice in various high-demand applications, thanks to their exceptional safety, long lifespan, and stability. At Himax Electronics, we emphasize the importance of proper charging techniques to maximize these benefits. Here’s a detailed guide on how to effectively charge a LiFePO4 battery to ensure optimal performance and extend its service life.
Detailed Understanding of LiFePO4 Battery Charging
Charging a LiFePO4 battery involves more than simply connecting it to a charger; it requires understanding the battery’s specific needs:
Optimal Charging Voltage: LiFePO4 batteries have a higher charging voltage compared to other lithium-ion cells. The precise voltage needed for charging is about 14.6 volts, which must be accurately delivered by the charger to avoid undercharging or damaging the battery.
Ideal Charging Current: The charge rate should ideally be tailored to the battery’s capacity. For a LiFePO4 battery, charging at a rate of 0.5C, where ‘C’ is the battery’s capacity in amp-hours (Ah), helps in maintaining its health. For example, a 100 Ah battery should ideally be charged at 50 amps to promote longevity and prevent stress on the battery.
Step-by-Step Guide to Charging Your LiFePO4 Battery
Selecting the Right Charger:
It’s crucial to use a charger specifically designed for LiFePO4 chemistry to accommodate its unique voltage and current requirements. Chargers tailored for LiFePO4 ensure that the battery is charged within safe limits, safeguarding against potential overvoltage or overheating.
Connecting the Charger:
Before connecting, ensure that the battery temperature is stable, ideally around room temperature, to optimize charging conditions.
Securely connect the charger’s positive lead to the battery’s positive terminal and the negative lead to the negative terminal, ensuring good contact and avoiding any loose connections which can lead to inconsistent charging.
Monitoring the Charge Process:
Although many modern chargers automate the charging process and stop charging once the optimal voltage is reached, monitoring the process can prevent faults. Keep an eye on the charger’s readings and be alert for any signs of abnormal behavior, such as a sharp drop in voltage or overheating.
Completing the Charge Cycle:
Once the charge cycle completes and the battery voltage stabilizes at around 14.6 volts, disconnect the charger. This prevents any risk of overcharging, which can reduce the battery’s lifespan and efficiency.
After disconnecting, check the voltage a few hours later or the next day to ensure the battery maintains the charge, indicating good battery health.
Advantages of Proper Charging
Effective charging practices significantly influence the performance and durability of LiFePO4 batteries:
Maximizing Battery Life: Proper charging ensures that each cycle is optimized to extend the battery’s operational life, significantly reducing the cost and frequency of replacements.
Optimal Performance: A well-charged battery delivers better performance, providing consistent output and improving the reliability of the device it powers.
Safety Assurance: Correct charging practices diminish the risk of battery failures and enhance the overall safety of the system in which the battery is used.
Advanced Tips for Battery Maintenance
Charging Environment: Always charge in a controlled environment; extreme temperatures can adversely affect the battery’s chemistry and charging efficiency.
Routine Inspections: Regularly inspect the battery for signs of damage or wear. Check the terminals and connectors for corrosion or buildup, and clean them as necessary to maintain optimal conductivity.
