Towards highly integrated energy storage solutions
TINY is a solid-state rechargeable thin film battery, introducing CEA-Leti’s latest electrochemical energy storage solution for IoT devices. This technology addresses companies’ rapidly growing interest in a range of integrated power sources that will help them embed higher energy density while reducing both the footprint and cost. TINY microbatteries make IoT devices even more compact and energy efficient. CEA-Leti's 100% solid state Lithium ion micro-batteries are manufactured using conventional MEMS production equipment. With typical sizes in the mm3 range, they safely operate within the μAh to mAh capacity.
CEA-Leti’s technology is tailored to several components including:
Wearable/implantable devices to be used in:• Medical and healthcare monitoring
Self-powered sensors to be used in:• Industry 4.0• Transportation• Buildings/structural health monitoring
Standby/back-up power to be used in:• Dust computing• Portable devices
