18250 630mAh 3.7V Rechargeable Li Ion Polymer Battery with 5A Pluse discharge Current
Features Overview of Li ion Polymer Battery
High energy, miniaturization, and lightweight: Polymer lithium batteries have high energy density and can achieve smaller size and lighter weight at the same capacity.
Ultra-thin features: Batteries of different shapes and capacities can be made to meet product needs. The theoretical minimum thickness can reach 0.5mm.
Good safety: using solid electrolyte, there are no flammability and leakage problems that may occur with liquid electrolyte, making it safer than lithium-ion batteries.
Small self-discharge: The self-discharge is small during storage and standby states, which is beneficial to extending battery life.
Long cycle life: The cycle life of polymer lithium batteries is generally higher than that of lithium-ion batteries, which can reach more than 500 times.
Flexible design and customizable appearance: The battery appearance can be customized according to the size of the battery compartment of the customer's product.
