Georgia Tech team develops melt-infiltration technique for scalable production of solid-state batteries

Green Car Congress

A new fabrication technique could allow all-solid-state automotive lithium-ion batteries (ASSLBs) to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes. O 2 cathodes and both Li 4 Ti 5 O 12 and graphite anodes. —Kostiantyn Turcheniuk, co-author.
