Flexible Lithium Battery for Smart Wearables

Lionrock develops flexible lithium battery for smart wearables.

Smart wearable devices are becoming common. There are vast variety of wearable devices for communication, activity tracking, biometrics, and health monitoring purposed. Most wearable devices require rechargeable battery to power. However, rechargeable battery remains in bulky and rigid form so far. Thus, rechargeable batteries are limiting wearable from smarter, lighter or more comfortable designs for users. Because of this limitation, we see the need of flexible batteries to make wearable devices even smarter.

Our Technology

Our flexible lithium batteries (LiB) are based on novel nanofiber sponge technology and its associated fabrication processes. The Nano and Advanced Materials Institute (NAMI) in Hong Kong is the R&D entity behind. The patented nanofiber structure makes the battery more durable, flexible, safer, higher ionic conductivity than convention LiBs.

This technology researched by NAMI has gained several awards, including the Gold Medal and Prize of the Chinese Delegation for Invention and Innovation in the 45th International Exhibition of Inventions of Geneva 2017. Find out more details about our flexible battery technology as well as its safety features.

Our Flexible Lithium Battery Product

Our batteries would benefit smart wearables in the following ways:

  1. Increase energy storage. Flexible lithium battery can fit into non-rigid and/or odd shape compartment of a device, thus much increase energy storage.
  2. Enable smarter product design. There is no more concern to house rigid or bulky battery. Flexible lithium batteries enable creativity for nicer / more comfortable product design.
  3. Easy to use. Despite breaking through conventional battery rigid form, flexible lithium batteries remain using lithium chemistry with the same operating voltage. Hence there is no extra concern on the electronics design aspect.
