ROCKING CHAIR TYPE LITHIUM SECONDARY BATTERY INCOMBUSTIBLE ELECTROLYTE AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To individually precipitate Li by adding a Li metal to a LiCl saturation bath because Al is far more precious than Li. SOLUTION: A Li metal with reduction capability is added to a LiCl saturation AlCl3 -EMIC bath (50mol% is deposited as Al on the Li metal, and local cell reaction is caused to dissolve the Li metal acting as Li in the bath. As a result, the remaining Al2 Cl<-> can be removed from the bath in order to provide the electrolytic bath where the Al cannot be deposited during cathode (charging) reaction.
