ITEN develops and manufactures rechargeable multilayered solid-state Li-ion micro-batteries in the form of SMD components. Such solid 3D micro-batteries are fully solid and consist of a stack of thin film layers of a few µm each.
One key advantage of ITEN dry lithium-ion 3D micro-batteries is to make it possible to reach high volumetric energy densities as shown on attached chart (Source: Journal of power sources, 282, 2015)
“Moore Law” is now reaching its physical limit and the electronics industry is aggressively looking for lowering power consumption and finding long life micro energy storage as an alternative to further downsizing.
Micro energy storage for power back-up and power loss protection also represents a multi billions of dollars opportunity, as they are critical to all RTC (real time clocks), SRAM, DRAM, SSD devices on circuit boards and as needs for data storage continue to grow.
Primary coin cells, supercapacitors are becoming too big, whereas micro-batteries with a few μAh of capacity store enough energy to insure power back-up functions.
Regarding connected devices, micro energy storage presented also a key issue.
Coins cells are not rechargeable or with poor cycle life, and do not have enough power for IOT sensors. Supercapacitors are cumbersome and show high self-discharge and poor calendar aging performances, and all these devices need specific additional and costly manufacturing steps for their integration.
Development of extremely tiny and price efficient energy storage devices are therefore critical for these multi-billion-dollar applications to grow further on a global scale.
