Abstract

A solid-state lithium battery including a lithium-containing anode and a phosphorus-containing cathode is disclosed. The cathode may include any of a number of electronically conductive allotropes of phosphorus, referred to as a group as black phosphorus. A solid discharge product of the cell acts as an electrolyte for the cell. The cathode may include an auxiliary electronic conductor phase to improve the conductivity of the cathode, improve the cathode utilization during discharge and reduce the overall cell impedance.

Claims (4)

1. A method of assembling a solid-state electrochemical cell comprising the step of:

placing a lithium anode and a phosphorus cathode in contact with each other without a pre-existing separator or electrolyte to form a lithium phosphide layer in-situ.

2. The method of claim 1 , further comprising connecting the anode electronically to a negative side of a cell container and connecting the cathode electronically to a positive side of the cell container.

3. The method of claim 1 , wherein the anode comprises lithium metal and the cathode comprises black phosphorus.
