Problem addressed

Battery life is a critical factor for IoT devices as large-scale battery replacement cost is much higher than the device itself.

Innovation
  • NAMI’s battery pack has an extreme low self-discharge current down to 1.5µA at room temperature which enables itself to keep over 85% of its capacity after 5-year storage. It also possesses a wide operation temperature from -40 to 85°C, expanding the application of the IoT devices to diverse geographic regions.
  • During data transmission under the popular LoRa, NB-IoT, LTE or GSM protocols, the battery can continuously provide constant voltage output of over 3.4V to lower signal loss during transmission which is significant when conventional primary batteries are used.
  • In addition, the battery pack’s form factor is flexible to fit different IoT devices.
Key impact
  • High power output efficiency
  • Constant voltage output
  • Up to 5A pulse current output
  • Safe and cost-effective
