Abstract

CSquared Innovations LLC has developed a novel plasma/laser manufacturing process for solid state thin-film Li-ion batteries which consolidates conventional material synthesis and deposition onto a single platform. This revolutionary technique can produce a fully solid state thin-film Li-ion cell in atmosphere with the ability to conformally apply the battery to nearly any surface. The equipment can produce the anode, solid state electrolyte, and cathode without pause and without changing hardware. Further, a larger variety of chemical precursors can be utilized to create the active materials compared to sputtering and vapor deposition techniques, allowing for independence from foreign sources of lithium and other rare earth materials. This layer-by-layer process can also retrofit thin-film Li-ion batteries to existing equipment (e.g. a UAV wing) or incorporate them into previously manufactured devices; no other process offers this feature. The overall objective of this proposal is to demonstrate that our novel plasma/laser manufacturing process can effectively create a solid state thin-film Li-ion cell which can meet capacity, internal leakage, shelf life, and cycle life specifications for pairing with energy harvesting applications.
