Recent advances in thin film solid state energy storage devices are enabling exciting new applications. Such batteries are created using semiconductor production techniques where cathodes, electrolytes and anodes of 10’s of μm thickness are deposited onto a carrier layer, in Ilika’s case a 6” wafer. Thinning and dicing the wafer results in discrete cells, about 150 μm thick, which can be stacked to form batteries. A 0.06 CC volume battery can store about 1 mAh.
Previously, the production of thin film batteries on expensive and sophisticated equipment placed the technology into a high value, but low volume, industrial category. Today’s applications are based around the high temperature capability (to 150°C), or the sub 1mm thickness of the thin film battery.
