Gel electrolyte and gel-electrolyte battery

摘要

A gel electrolyte and a gel-electrolyte battery are disclosed which have an improved cycle characteristic and preservation easiness at high temperatures. The gel-electrolyte battery incorporates a positive-electrode mix layer (3), a negative-electrode mix layer (5) and a gel-electrolyte layer (6). The gel-electrolyte layer contains a plasticizer which contains lithium salt, a matrix polymer for dispersing the plasticizer and fibrous insolubles. The fibrous insolubles are contained in the gel electrolyte in a quantity not less than 0.1wt% nor more than 50wt%. The ratio of the length and diameter of the fiber is not less than 10 nor more than 3000. The length of the fiber is not less than 10 mu m nor more than 1cm and the diameter of the fiber is not less than 0.05 mu m nor more than 50 mu m.
