Abstract
A lithium-aluminum alloy electrode having from about 10% to 95% by weight of lithium is formed by contacting a preformed lithium-aluminum laminate with a solution of a lithium salt in an organic solvent. Preferably the laminate is supported on a wire mesh support structure.
Claims13
A method of making a lithium-aluminum alloy electrode comprising:
- a. forming a laminate having at least one ply of aluminum sheet material and one ply of lithium sheet material;
- b. contacting the laminate with a solution of a lithium salt dissolved in an organic solvent for a time sufficient for alloy formation to occur.
The method of forming a lithium-aluminum alloy electrode comprising:
- pressing a sheet of lithium metal onto a metal mesh support structure;
- pressing aluminum sheet material on each major surface of said lithium pressed on said wire mesh, thereby forming a laminated structure, said aluminum sheet material being perforated, the weight ratio of aluminum sheet material to lithium sheet material being in the range of from about 10% to about 95% by weight;
- contacting said laminated structure with a nonaqueous organic solution of a lithium salt for a time sufficient for alloy formation to occur.
