Solid or gel electrolytes are used instead of liquid electrolytes to avoid leakage and combustion risks. Even if short-circuited or overheated, it will only swell and deform instead of explode. Equipped with multiple protection mechanisms (such as overcharge/discharge protection, PTC components, etc.), international certification (such as IEC 62133-2 standard) ensures safe use.
The aluminum-plastic soft packaging structure reduces the weight of the battery by 20%-40%, and the thickness can be less than 0.5mm, which is suitable for ultra-thin devices (such as folding screen mobile phones and wearable devices). Compared with traditional liquid batteries, polymer batteries have a smaller volume while maintaining the same capacity.
Some models support 2C rate fast charging (such as some polymer lithium batteries), with an energy density, and a battery life extended by 1.2 hours.
