French solid-state battery manufacturer ITEN has produced its one-millionth battery and expanded its Powency range with a 1,500µAh surface-mount device.
The new battery is available for sampling and is being evaluated by selected customers. Volume production is planned by the end of 2026.
ITEN said the device stores six times more energy than its existing 250µAh Powency battery and offers higher peak-current capability. It is intended for space-constrained Internet of Things and medical applications requiring longer operating or backup times.
The battery is designed to support ultra-wideband, LoRa and Bluetooth Low Energy communications. Potential applications include asset trackers, connected healthcare products, smart-building sensors, remote controls and energy-harvesting systems.
As an SMD component, the battery can be mounted directly onto an electronic assembly without a separate battery holder. ITEN said this could provide an alternative to larger energy-storage components, including supercapacitors, in highly integrated devices.
CEO Vincent Cobée said the one-million-unit milestone demonstrated the company’s accumulated knowledge of solid-state technology, product development and volume manufacturing.
“It gives us a strong industrial foundation as we continue to push energy storage towards greater integration, power and safety,” he said.
ITEN makes its batteries using proprietary nanomaterials and full-ceramic mesoporous electrodes. The cells contain no liquid electrolyte. The company said its low-temperature sintering process preserves material properties while increasing the electrodes’ specific surface area, supporting high-power performance.
The company opened its Dardilly pilot plant near Lyon, France, in April 2024 following an investment of €14 million ($16.4 million). The facility brings together processes ranging from materials chemistry to cell testing and has installed capacity exceeding 30 million devices annually.
ITEN claims it is the only company to have reached this level of production maturity for solid-state batteries intended for electronic systems and ready for shipment.
