Abstract: |
In the method for preparing battery of lithium - iron disulphide, lithium foil is as negative pole; coating pulp of iron disulphide on basal body of metal tape material forms positive plate; polypropylene microporous membrane is adopted as diaphragm; and adding monomer of methyl methacrylate and initiator to solvent system including lithium perchlorate - propylene carbonate etc. prepares electrolyte. After assembling battery pack, the method heats up and polymerizes methyl methacrylate so as to form gel electrolyte of polymethyl methacrylate and lithium perchlorate - propylene carbonate. Thus, the invention raises safety and storage quality. Features are: low cost, high performance, and long storage period, simple technical flow, and easy of industrializied production. |
