Electronic connection in an all-solid state battery at the anode/electrolyte interface

A solid-state battery comprising a lithium metal anode or a lithium-indium alloy anode, a cathode comprising a surface and an interior region, said interior region comprising a phthalocyanine solid-state electrolyte and said surface comprising a layer of phthalocyanine solid-state electrolyte, and a solid electrolyte interphase, said solid electrolyte interphase connecting said phthalocyanine solid-state electrolyte and said lithium metal anode, said solid electrolyte interphase comprising lithium fluoride and an organic amorphous layer that are reaction products of lithium bis(fluorosulfonyl) imide in dimethoxyethane, and a mixture of 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether and fluoroethylene carbonate, said solid-state battery having a discharge rate of:

• a) from about seventeen hours, C/17, to about 2.83 hours, C/2.83, at 23° C. with at least 97% capacity;
• b) from about 8.5 hours, C/8.5, at 0° C. with at least 80% capacity;
• c) from about three hours to about one hour at 23° C. with at least 97% capacity;
• or
• d) from about three hours to about one hour at 0° C. with at least 80% capacity.
