Drain-On-Demand Lithium Battery for Long-Life IoT Devices
Overview
NAMI has developed an energy-dense non-rechargeable lithium battery specially designed for high-power and long-life IoT devices.
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
