For end applications such as handheld printers, POS terminals, and smart wearables, battery cells are required to have excellent rate performance due to the high instantaneous operating current and limited battery compartment volume. In response to this demand, BAK Battery has developed mature and stable high-rate small polymer battery cells.
In terms of capacity, BAK Battery's polymer batteries cover a range from 20mAh to 10000mAh, meeting the power requirements of different end products, and all support fast charging and high-rate discharge. The 7C discharge capacity retention rate of its high-rate small polymer battery cells reaches over 85%, and the 1C charge/7C discharge cycle at room temperature can meet the requirement of 300 cycles. This ensures that under high-power output conditions, the devices can achieve long battery life and continuous fast charging, guaranteeing the normal operation of the devices.
For example, in the application of handheld printers, high-rate small polymer battery cells can quickly provide large currents when the printer is working at high speed, ensuring the efficient completion of printing tasks. At the same time, they maintain a long battery life, reduce the frequency of charging, and enhance the user experience. In smart wearables, such as smart bracelets, the small-sized high-rate small polymer battery cells provide sufficient power within the limited space, meeting the continuous power demand of the bracelet's functions such as real-time heart rate monitoring and sports data tracking. Additionally, they support fast charging, allowing users to continue using the device after a short period of charging, which greatly improves the convenience and practicality of the device.
