ITEN micro-batteries are all rechargeable 3D solid-state batteries operating on a broad operating temperature range (up to -40°C +85°C) and featuring lifespan from 10 to 20 years.
Their high energy storage density is ideal for applications where very small footprints are required; in addition, their disruptive technology enables storing energy but also delivering high power and peak currents (e.g. a 500µA.h micro-battery can deliver peak currents up to 200mA) required to power up RF transmissions under various protocols (BluetoothTM, ZigbeeTM, LoRATM, SigfoxTM, NB-IoTTM or LTE-MTM) for data delivered by autonomous wireless sensors. All that in a footprint of a few mm² and a volume of around 12mm3.
For specific applications, the micro-battery thickness can even be cut down to 330µm. The same technology enables very fast recharging of the micro-battery at constant voltage: the time to recharge the micro-battery to a SOC of 50% is less than 60 seconds. Designers of electronic systems shall also like the low self-discharge rate and their ability to withstand more than 2000 charge/discharge cycles at 75% DOD (@room temperature).
One other significant advantage is that ITEN micro-batteries are designed to operate at high temperature and are not sensitive to short circuits specially during assembly: they can indeed be handled by any automatic PCB assembly line, like any other SMD component.
In addition, solid-state micro-batteries are safe, not flammable (neither Lithium metal, nor organic electrolytes) and are recyclable like any other SMD component. Evaluation kits are available for most of the micro-batteries of ITEN portfolio.
Since ITEN micro-batteries are manufactured by stacking elementary cells, the sizes and capacities of the micro-batteries can be easily customized and tailored to meet your use cases. In case you would not find in the following table the ideal micro-battery meeting all your requirements, please feel free to contact us and discuss your bespoke micro-battery at sales@iten.com.
