TINY batteries
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.
What's new?
To achieve miniaturized and ultra-high energy density microbatteries, CEA-Leti worked on an aggressive design and very thick electrode (20+ μm) device architectures, the whole being achieved using advanced microfabrication technologies. The TINY batteries exhibit 5 mm² of footprint, a total thickness of 100 μm and 20 μAh of discharge capacity, which is the highest reported energy density for microbatteries with such dimensions.
