Science Daily  August 29, 2023 The power capability of Li-ion batteries has become increasingly limiting for the electrification of transport on land and in the air. The specific power of Li-ion batteries is restricted due to the required cathode thickness of a few tens of micrometers. Researchers in Switzerland have developed a design of monolithically stacked thin-film cells that had the potential to increase the power ten-fold. They demonstrated an experimental proof-of-concept consisting of two monolithically stacked thin-film cells. Each cell consisted of a silicon anode, a solid-oxide electrolyte, and a lithium cobalt oxide cathode. The battery could be cycled […]
