PREPARATION OF HIGH PERFORMANCE GAMMA-TYPE MANGANESE DIOXIDE AND BATTERY USING SAID MANGANESE DIOXIDE

摘要

PURPOSE: To obtain a high-performance γ type manganese dioxide which allows easy pulverization, has high electrical conductivity and has an excellent discharge characteristic when used as a positive pole material of a battery. ;CONSTITUTION: The short fibers of carbon fibers or graphite fibers provided with the films of manganese oxide on the surfaces are dispersed into a manganese electrolyte and the eutectoid of the short fibers with the manganese dioxide is effected by an electrolysis, by which the battery consisting of the highperformance γ type manganese dioxide contg. ≥90 wt.% M_nO₂ as its positive pole material is produced.;COPYRIGHT: (C)1993,JPO
