Happy to welcome you and discuss your battery requirements!

ITEN specializes in the design and production of solid-state and eco-friendly micro-batteries which can be recharged at a constant voltage and in just a few minutes. Being only a few millimeters in size, its batteries deliver high power (C-rates > 120) and current pulses (10-70mA) to power actuators, sensors, and RF transceivers (LoRa, UWB, Zigbee, BLE), to act as a power back-up (RTC, microcontrollers and volatile memories) in case of power loss or to store energy from harvesters and create autonomous solutions. They are totally safe (with no risk of thermal runaway) and operate over -20°C +70°C. They can be integrated into a multitude of products as a power back-up solution or for applications like autonomous IoT sensors, data loggers, beacons or RF tags, electronic labels, active styluses, remote controllers, or even medical devices. Having more than 300 patents worldwide, ITEN has raised 80 million euros in equity in Q4/2022 to set up a second high volume production site.


  • 100µA.h and 250µA.h Solid-state micro-batteries
    Safe SMD solid-state micro-batteries: size 10-35mm3, rechargeable to 80% in #7mn, operating -20°C+70°C, able to deliver peak currents (10-30mA) to power actuators, sensors, & RF (LoRa, BLE, UWB, Zigbee), to back-up (RTC) or to store energy from harvesters...

  • Such micro-batteries are really tiny, with XY dimensions like 4,5 x 3,2 mm and with thicknesses  less than 3mm.

    In addition, thanks to our 3D technology, we can easily customize the form factor of the micro-batteries, to make them very thin (down to 330-400 µm like in smart cards or tags) or very long (active stylus for smartphones and tablets)

    The peak currents delivered by such batteries are in the range of 120 times the capacity:  As an example a 250µA.h is able to deliver peak currents as high as 30mA.

    This is more than enough to power sensors, accelerometers (to wake up a system), e-Paper displays, Bluetooth or longer range connectivity (LoRa), etc.

    Such batteries are also able to recharge from 0 to 80% in # 6-7 minutes, which is a key feature for consumer applications.

    Since they can be recharged at constant voltage (like a capacitor), the Bill-Of-Material for the charging circuit can be very low.

    But alternative ways of charging can also be considered: NFC, Qi/induction, USB, energy harvesting.

    Unlike many conventional batteries, the solid-state micro-batteries are also compatible with reflow soldering at 165°C (

    The operating temperature range of our micro-batteries is presently -20°C + 70°C and will be extended to -40°C +85°C soon.

    More generally, these micro-batteries are typically used

    • to back-up RTC, microcontrollers and volatile memories (in case of failure or shutdown of the main power supply) and/or to send alerts to a distant hub;
    • to power autonomous and wireless sensor networks, sensor data loggers, tags, beacons or mobile phone peripherals;
    • To store energy collected from energy harvesters and deliver the required power to RF transmitters (BLE, UWB, Zigbee, LoRa);
    • To power-assist primary batteries and deliver the power to boost any RF communication (Bluetooth, UWB and LoRa):
    • To act as power and energy reserve for initialization purpose and cold start,
    • To replace some bulky supercapacitors, without the aging issues and with higher energy and power densities.

    It enables totally safe (no risk of thermal runaway or explosion) and eco-friendly electronic hardware design (no toxic materials no heavy metals inside, no solvents, nor exotic materials like rare earths) with significant advantages in terms of carbon footprint (not only at the battery manufacturing level itself but also for the battery SMD  integration into the electronic systems) .

    Since the batteries are solid-state and ceramics-based, their chemical stabilities are quite good, between 10 and 20 years., also due to the internal moisture barrier.

    They are very robust and are compatible with high number of charge/ discharge cycles, even at 100% depth of discharge. Batteries can even be stored fully discharged without any issues.

    They can be thus combined with energy harvesters (like solar cells)  to make your solution fully autonomous

    Last but not least, such batteries do not require any specific recycling process and can be recycled like any other ROHS devices (a microcontroller or a memory for instance).

    In this respect, such battery offering comes perfectly with the scope of the European battery directive recommending to get rid of all coin cells and non-rechargeable batteries in electronics designs by year 2030.
