What causes lithium batteries swelling?
Lithium-ion polymer batteries are widely used due to their long life and high capacity. However, there are some issues that can arise, such as swelling, unsatisfactory safety performance, and accelerated cycle life attenuation.
What is the difference between lithium polymer battery and li-ion polymer battery?
Lithium polymer battery ( Li-polymer battery ), is a chemical battery. Compared with the previous battery, it has the characteristics of high energy, miniaturization and light weight. Lithium polymer batteries have ultra-thin features, and can be made into batteries of different shapes and capacities to meet the needs of some products. The theoretical minimum thickness can reach 0.5mm.
Polymer Lithium-ion Battery UL1642 Certification
What's UL1642 certification? What's UL1642 standard for polymer lithium-ion battery? What's the test items of UL1642 certification?
Why does the lithium-ion battery capacity become lower in winter?
Since the lithium-ion battery entered the market, it has been widely used due to its advantages such as long life, large specific capacity and no memory effect. Low-temperature use of lithium-ion batteries has problems such as low capacity, severe attenuation, poor cycle rate performance, obvious lithium evolution, and unbalanced lithium extraction. However, with the continuous expansion of application areas, the restrictions brought by the low-temperature performance of lithium-ion batteries have become more and more obvious.
Safety performance comparison of lithium cobaltate battery, lithium iron phosphate battery and polymer lithium battery
Safety comparison of lithium cobaltate, lithium iron phosphate and polymer lithium batteries. Many customers have a lot of disputes about the safety performance of lithium batteries. Compared with lithium cobalt oxide batteries and polymer lithium batteries, the most obvious advantage of lithium iron phosphate batteries is the extremely high safety factor and support for fast charging (high current charging). And a wider operating temperature range.
