It is understood that this technological advancement is based on ITEN's unique expertise in nanomaterials to design all-ceramic electrodes with patented mesoporous structures, which significantly increases their specific surface area.
The technology will be used in its Powency? product series, which is a 150μAh micro solid-state battery with an area of 18mm2, which can be used in IoT applications such as wireless sensors, and is expected to be fully produced in the second half of 2025.
ITEN's Dardilly pilot line can produce more than 30 million batteries per year, and plans to launch a high-capacity manufacturing plant by 2028 to meet the growing market demand.
Regarding the 200C discharge rate, it means that the battery can release a current intensity of 200 times the rated capacity in a short period of time, which is suitable for specific high-power scenarios, but it needs to be combined with battery design, capacity and actual application conditions for comprehensive analysis.

Theoretically, when discharged at 200C, the battery can release all its power within 3 minutes. This technology is mainly used for equipment that requires instantaneous high power output, such as model aircraft, drones, and competitive racing.
In actual applications, 200C discharge usually only lasts for a few seconds to tens of seconds to avoid overheating or permanent damage to the battery. In addition, high-current discharge will generate a lot of heat, which requires an efficient heat dissipation system, and frequent high-rate discharge will accelerate the aging of electrode materials and shorten the battery cycle life.
But no matter what, the development of a solid-state battery with a 200C discharge rate and its full production in the second half of 2025 is enough to show that solid-state batteries have achieved results in the direction of discharge rate, which may also bring inspiration to the charging of solid-state batteries to a certain extent.
According to the data, ITEN is a high-tech company in France that focuses on the research and development and production of solid-state batteries for microelectronic applications. Its core product is a high-power density all-solid-state lithium battery, which mainly serves the instantaneous energy needs of IoT devices, smart hardware and other fields.
ITEN's technical path is characterized by miniaturization and ultra-low power consumption. The product volume is only 25mm3 and weighs 73 mg, which is suitable for scenarios such as wireless sensor networks.
ITEN has completed trademark registration in China since 2020 (registration number 44468237), and its business covers the global market.
ITEN was selected as one of the "Top 120 French Technological Innovations" in 2023 and was listed as a representative company in the field of microbattery technology, alongside innovative companies in the fields of energy efficiency and carbon management.
In November 2024, ITEN announced the start of industrial-scale production of solid-state batteries, including two models, PWY0150S (150μAh) and PWY0250S (250μAh), both of which use solid-state lithium-ion technology and support short-term high-power output (such as powering LAN devices).
