The aim of the project is an economically viable design for “all-solid-state” rechargeable batteries. Eliminating organic liquid electrolytes from lithium-ion batteries will dramatically increase safety, range of operating conditions, lifetimes, and energy density. The key technical challenge is keeping solid-solid interfaces intact over thousands of charge/discharge cycles. We will address this by inserting inorganic interfacial layers that change smoothly from hard ceramic to flexible glass and back again, through rigorous chemical design and synthetic control. This will reduce the stress that causes mechanical failure, while increasing chemical stability so that the latest generation of high-power electrodes can be brought into service.Read moreRead less
