Abstract
A lithium ion battery cell. The lithium ion battery cell includes a lithium-based anode, a cathode, and a solid-state electrolyte positioned between the lithium-based anode and the cathode. The cathode comprises an alkylammonium cation lithium phthalocyanine anion complex. The solid-state electrolyte comprises an alkoxyalkylammonium cation lithium phthalocyanine anion complex.
Claims14
A lithium ion battery comprising:
- a plurality of lithium ion battery cells arranged in a series such that the anode of one lithium ion battery cell of the plurality is adjacent to the cathode of another lithium ion battery cell of the plurality, the lithium ion battery cells of the plurality further comprising:
- a lithium-based anode;
- a cathode;
- and
- a solid-state electrolyte comprising an alkoxyalkylammonium cation lithium phthalocyanine anion complex, wherein the solid-state electrolyte is positioned between the lithium-based anode and the cathode;
- a negative terminal adjacent to the anode of the outer most one lithium ion battery cell of the plurality;
- and
- a positive terminal adjacent to the cathode of the outer most one lithium ion battery cell of the plurality.
A solid-state electrolyte material for use in a lithium ion battery, the solid-state electrolyte material comprising:
- an alkoxyalkylammonium cation lithium phthalocyanine anion complex.
A method of manufacturing a lithium ion battery cell, the method comprising:
- preparing a solid-state electrolyte comprising an alkoxyalkylammonium cation lithium phthalocyanine anion complex;
- applying the solid-state electrolyte to a lithium-based cathode;
- optionally, thermally processing the solid-state electrolyte on the lithium-based cathode;
- applying a lithium-based anode to the solid-state electrolyte opposing the lithium-based cathode;
- and optionally, thermally processing the lithium-based cathode with the solid-state electrolyte and the lithium-based anode.
