COMPOSITE CATHODE, MANUFACTURE THEREOF, AND ITS USAGE IN SOLID ELECTROLYTIC BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a composite cathode comprising an activated cathode material, an electron conductor, and a polymer electrolytic substance. SOLUTION: This composite cathode contains a cathode active material powder, an activated conductor powder, and an electrolytic substance containing as an indispensable component a polymer composition containing a polymer produced by polymerizing a vinyl ether having a formula; R-[-O-CH2 -CH2 -]n -O- CH=CH2 (wherein R stands for methyl or ethyl; n=1-16 integer); and a divinylether having a formula CH2 =CH-[-O-CH2 -CH2 -]m -O-CH=CH2 (wherein m=1-10 integer) at a mole ratio in a range from (98:2) to (40:60) of the vinyl ether to the divinylether and either solely lithium tetrafluoroborate (LiBF4 ) or a mixture with another lithium salt.
