Designed for medical devices, IoT sensors, and wearable technology, these lightweight lithium batteries combine ultra-low profile (as thin as 0.6mm) and customizable shapes to fit compact spaces. With high energy density (250-300Wh/kg) and stable discharge, they power smartwatches, implantables, wireless trackers, and medical monitors. Enhanced safety features (temperature resistance, puncture protection) ensure reliability in sensitive environments.
