Our flexible lithium ion batteries (LiBs) are based on a novel nanofiber sponge technology and its associated fabrication processes researched and developed by the Nano and Advanced Materials Institute (NAMI) in Hong Kong. The patent pending nanofiber structure makes the battery ultra-lightweight, more durable, flexible, safer, higher energy density and ionic conductivity than convention LiBs.
Researched since 2014, the technology has gain several awards including most recently the Gold Medal and the Prize of the Chinese Delegation for Invention and Innovation in the 45th International Exhibition of Inventions of Geneva 2017.
- Ultra-thin – The complete packaged battery is 1.35mm thick.
- Bendable & Twistable – The battery has high flexibility. In our bending tests, it maintain stable performance after 1000 cycles of bending radius 20mm. (See Figure below)
- Enhanced Energy Density – The battery support high current. It can support 1C charging and discharging.
- Safety – The nanofiber maintains a stable and safe electrolyte medium. Even if the battery is cut or pierced, there is no overheating or explosion. It will maintain power supply for a short period of time.
- Customizable Form Factor – Lionrock has the flexibility to tailor make the battery to fit different dimensionsoffers customized form factor to suit the need of wearable industry startup ecosystem.
