1. Relatively, the problem of battery leakage is improved, but it has not been completely improved.
2. Can be made into a thin battery: With a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm.
3. The battery can be designed in various shapes.
4. It can be made into a single high voltage: the battery with liquid electrolyte can only obtain high voltage by connecting several batteries in series, while the polymer battery can be made into a multi-layer combination in a single battery to achieve high voltage because there is no liquid.
