Flexible Lithium-Ion Battery Boards | Ultra-Thin, High-Performance Power Solutions for Wearables & Implants
Engineered for ​cutting-edge wearable devices and ​medical implants, our ​flexible lithium-ion battery boards combine the ​durability of polyimide (PI) with ​ultra-thin profiles to deliver ​high energy density and ​biocompatible performance. Ideal for smartwatches, ECG monitors, and implantable devices, these boards support ​wireless charging and ​long-term operation while minimizing bulk and ensuring safety compliance.

 

Key Features:

  • Advanced Flexibility: ​**≥100k flex cycles** (PI zones) withstand repeated bending in wearable electronics and hinged medical devices
  • High-Power Efficiency: ​200–500 W/L energy density powers 4K cameras, AI sensors, and long-lasting ECG monitors with minimal heat generation.
  • Biocompatible Design: ​ISO 10993 certified materials and ​non-toxic electrolytes ensure safety for in-body applications, meeting ​MIL-STD-883J reliability standards
  • Thermal Management: ​Graphene-enhanced substrates and ​built-in PTC thermistors prevent overheating during high-current discharge (e.g., wireless earbuds).
  • Precision Manufacturing: ​Laser-drilled vias and ​100% AOI/X-ray inspection ensure zero defects in micro-interconnects and battery cell integration.

Ideal Applications:

  • Consumer Electronics: Ultra-slim smartwatches, fitness trackers, and foldable smartphones with ​integrated batteries.
  • Medical Devices: Implantable defibrillators, neural stimulators, and continuous glucose monitors requiring ​sterilization resistance and ​biocompatibility
  • Industrial Wearables: Rugged battery solutions for factory workers and emergency responders in ​harsh environments.
