SILICA-COATED CARBON BLACK, ELECTRODE COMPOSITION IN WHICH SAME IS USED, ELECTRODE FOR SECONDARY CELL, AND SECONDARY CELL

Document Type and Number:

WIPO Patent Application WO/2016/084909

Kind Code:

A1

Abstract:

The ratio of DBP absorption to compressed DBP absorption of carbon black (DBP absorption/compressed DBP absorption) is 2.2 or less, and silica-coated carbon black in which the silica is a hydrolyzed condensate of a tetraalkoxysilane having a specific structure is used to obtain longer service life of a cell, as well as good electroconductive characteristics and dispersibility.
