3.2v 300ah lifepo4 battery.Can polymer lithium batteries be shipped or not?

　　Lithium (Li) is a very active metal element that undergoes chemical reactions with many substances. Lithium metal will spontaneously ignite when it comes into contact with water.

　　Lithium has not been given much attention since its discovery by humans, until in recent decades, with the rise of electronic products, lithium and its chemical products have been widely used in battery power supplies, such as lithium batteries and power banks, greatly facilitating our daily lives. But at the same time, safety hazards have also been buried around us, with lithium batteries/power banks (liquid media) experiencing frequent spontaneous combustion accidents due to external impact, compression, and other reasons.

　　According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. Liquid lithium-ion batteries have always occupied the vast majority of the market share of lithium batteries and power banks due to their advantages such as simple process and low price. In recent years, due to the increasing safety requirements for lithium batteries and power banks, polymer lithium-ion batteries with better safety performance and foldability have become increasingly common in the market and are gradually increasing their market share.

　　Polymer lithium-ion batteries use solid polymers as electrolytes, which can be either "dry" or "colloidal", making the electrochemistry of polymer lithium-ion batteries more stable. Their resistance to external forces such as drop and compression is greatly improved compared to liquid lithium-ion batteries, and they have advantages such as long lifespan, large capacity, small weight, and good safety performance.

　　Polymer lithium-ion batteries, including polymer batteries, polymer cell charging banks, polymer lithium batteries, polymer charging banks, back clip batteries, back clip charging banks, and electronic products powered by polymer lithium-ion batteries, are all allowed to be shipped.
