Small polymer lithium battery plays a vital role in modern electronic devices, especially in the fields of smart phones, wearable devices and drones, which have extremely high requirements for the charge and discharge rate of batteries.
Reasonable charge and discharge control is the key to prolonging the cycle life. Avoid overcharging and over-discharging, and charge and discharge the battery when the remaining power is between 20% and 80%.
Under high-rate charging conditions, the balance between safety and life of polymer lithium-ion battery is a complex issue, involving many aspects such as battery materials, design and usage conditions.
