It's hard to say which is better, polymer battery or lithium battery. Both of them have their own advantages, so polymer batteries are more used in small-scale applications, while lithium batteries have more prospects in large-scale applications, which are more environmentally friendly and safe.

1, poor shaping

Polymer batteries can be made very thin, any size and any shape, because its electrolyte can be solid and colloid instead of liquid, while lithium batteries use electrolyte and need a solid shell as a secondary package to contain electrolyte. So this also adds some weight to the lithium battery.

2. Safety.

At present, most polymers are soft-package batteries, with aluminum-plastic film as the shell. When organic electrolyte is used inside, even if the liquid is very hot, it will not explode, because the aluminum-plastic film polymer battery is in solid or colloidal state, so it will not leak, but will naturally rupture. However, nothing is absolute. If the instantaneous current is large enough, it is not impossible for the battery to spontaneously ignite or burst, which is the reason for the safety accidents of mobile phones and tablet computers.

3. Battery voltage

Because polymer batteries are made of polymer materials, they can be made into multi-layer combinations to achieve high voltage, while the nominal capacity of lithium battery batteries is 3.6V In practical application, in order to achieve high voltage, it is necessary to connect multiple batteries in series to form an ideal high voltage working platform.

The new generation of polymer lithium-ion battery can be thin (ATL battery can be as thin as 0.5mm, which is equivalent to the thickness of a card), with any area and any shape, which greatly improves the flexibility of battery modeling design, enables it to be made into batteries with any shape and capacity, meets the product requirements, provides application equipment developers with high design flexibility and adaptability of power solutions, and maximizes product performance.

At the same time, the unit energy of polymer lithium-ion battery is 50% higher than that of ordinary lithium-ion battery, and the capacity, charge-discharge characteristics, safety, working temperature range, cycle life (more than 500 times) and environmental protection performance are greatly improved compared with lithium-ion battery? .
