Ultra Thin Lithium-ion Polymer Battery Features

Customizable Design: Supports ultra-thin and irregular form-factor customization to fit compact internal device spaces.
Safe & Reliable: Polymer electrolyte with no risk of liquid leakage, and a low probability of thermal runaway during overcharging or short circuits.
Stable Discharge: Supports stable discharge at ultra-low currents, with smooth voltage output and no sudden drops.
Long-Term Charge Retention: Monthly self-discharge rate of less than 3%, helping retain power during extended storage.
Long Cycle Life: ≥500 cycles with 80% capacity retention. In wearables and similar devices, typical shallow charge/discharge patterns can further extend service life.
High Energy Density: 150–250 Wh/kg, balancing lightweight, ultra-slim device design with runtime requirements.
