High Voltage Li-polymer battery 402830 3.8V 430mAh Lipo Batteries for Medical Device
Features Overview of High Voltage Battery
The core technology of high voltage polymer lithium ion battery is high voltage electrolyte system. Compared with traditional lithium-ion batteries, high-voltage polymer lithium-ion batteries use a more stable and safer polymer electrolyte material, allowing the battery to operate at higher voltages. This high voltage electrolyte system can not only improve the energy density of the battery, but also reduce the internal resistance and energy loss of the battery, thereby improving the efficiency and cycle life of the battery.
