Publication number: 20240136574Abstract: The present invention relates to a solid-state battery that is based on a phthalocyanine solid-state electrolyte/anode connection that is chemically obtained. Such chemical connection process yields a solid electrolyte interphase that connects the solid-state battery's phthalocyanine solid-state electrolyte and anode. Unlike other processes for forming solid-state electrolyte/anode connections, the present chemical process does not require that solid-state electrolyte be ductile and flow under high pressure.Type: ApplicationFiled: December 14, 2023Publication date: April 25, 2024Inventors: Lawrence G. Scanlon, William A. Feld, Jacob W. Lawson, Leah R. Lucente
