Battery life is a critical factor for IoT devices as large-scale battery replacement cost is much higher than the device itself. NAMI has developed a series of long lasting batteries for IoT devices with doubled battery life. The battery pack has an extreme low self-discharge current down to 1.5 µA at room temperature which enable the battery pack to keep over 85% of its capacity after 5-year storage and 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 over 3.4V and lowers 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.
