NEGATIVE ELECTRODE FOR SECONDARY CELL, SECONDARY CELL, AND METHOD FOR PRODUCING NEGATIVE ELECTRODE FOR SECONDARY CELL

摘要

A multilayer negative electrode having a first carbon layer enabling a high charging/discharging efficiency by a simple method, enabling a good cycle characteristic to be maintained, and realizing a high cell capacity in the voltage range of when the cell is actually used. A first layer (2a) the major component of which is carbon and a second layer (3a) the major component of which is a filmy material having a lithium ion conductivity are formed over a copper foil (1a). The second layer (3a) is formed by dispersing at least one kind of metal particles, alloy particles, and metal oxide particles in a solution in which a binder is dissolved and applying and drying the coating solution.
