AbstractWe propose to use a high rate manufacturing technology recently developed at Excellatron to deposit all-solid-state thin film batteries on an ultra-thin substrate. The all-solid-state lithium batteries have very high cycle life (>10,000 charge/discharge cycles), a wide operating temperature range, a rapid recharge capability, and increased power densities. They are inherently safer than existing lithium-ion and lithium-polymer. Currently, their large-scale applications were mainly limited by two factors. One is that thick substrates used in the production process limited their practical energy density. Another is the high production cost due to the low deposition rate of the thin films. Proposed work will address both problems at the same time. The ultra-thin polymer substrate used in this work will largely increase the real energy and power density of the battery. The battery will be prepared by a high rate deposition technology recently developed by Excellatron. Low cost manufacturing of thin film batteries on ultra-thin substrate will be ideal to support the next generation of high power systems used in advanced vehicle applications such as electric trucks, hybrid electric step vans and buses.
