NEGATIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL AND METHOD FOR MANUFACTURE THEREOF, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL

摘要

A negative electrode for a non-aqueous electrolyte secondary cell, characterized in that it comprises a collector, a first coating layer comprising tin, a tin alloy, aluminum, an aluminum alloy formed on the surface of the collector, and, formed on the first layer, a second coating layer comprising a metal being low with respect to the capability of forming a compound with lithium. Another first coating layer may be formed on the second coating layer, and further, an uppermost coating layer comprising copper or the like may be formed thereon. The negative electrode is capable of achieving desired performance capabilities through the formation of each of the above coating films by means of a heat treatment, which allows the manufacture of the electrode at a markedly reduced cost, since the heat treatment is carried out in a very short time.
