Problem addressed

To address the higher power and/or energy density requirement for rising disposable medical capsule applications, ASTRI has developed a high-capacity rechargeable lithium-ion energy storage technology.  ASTRI's design employed micro-nano structured silicon/carbon composite which aids to nearly double the anode specific capacity (700 vs 370 mAh/g) of Li-ion energy storage device for disposable medical capsule applications.

Innovation
  • Nano-size Si aggregate provides fast Li ions diffusion pathways;
  • Micro-size C-based conglomerate accommodates volumetric expansion of Si and maintains the integrity of anode;
  • Environmental-friendly and low-cost process.
Key impact
  • Pain relief and easy to swallow due to reduced size;
  • High capacity enables high resolution imaging;
  • Supports pre-tune of medical device and achieves high accuracy.
Application
  • Disposable medical capsule
