Commercialisation opportunities
Non-exclusive licensing
Problem addressed

IoT devices could suffer from signal loss due to the undesired fading of power drain capability of conventional lithium thionyl chloride battery.

Innovation
  • NAMI's lithium battery provides extreme low self-discharge, close-to-theoretical capacity even after long-term storage, and high power under high discharge current, which are enabled by drain-on-demand passivation coating and pore manipulation carbon materials introduced inside the battery.
Key impact
  • Ultralow self-discharge rate
  • High power output after long term storage
  • High-capacity output under high current discharges
Award
  • Winner of 2022 R&D100 Awards
  • Gold Medal at the “2023 Geneva International Exhibition of Inventions”
Application
  • Wireless logistic trackers
  • Smart meters
  • eCall In-vehicle system backup battery
  • Wireless IoT sensors
