METHOD FOR MANUFACTURING POSITIVE PLATE OF Li/SO BATTERY Russian patent published in 2005 - IPC

Abstract RU 2249885 C2

FIELD: electrical engineering; manufacture of positive plates for lithium power supplies.

SUBSTANCE: proposed method for manufacturing positive plates of Li/SO₂ batteries includes application of cathode mass in the form of mixture of copper powder, soot, and binder onto current collector followed by sintering, whereupon plate is impregnated with saturated solution of lithium chloride in organic solvent for minimum 10 min.; then solvent is removed, and plate is calibrated in thickness, mass proportion of lithium chloride to copper powder being 0.45 to 0.65.

EFFECT: enhanced battery discharge characteristics, service life, and capacity stability in cycling due to enhanced capacity of positive plate.
