Abstract
A negative electrode for a secondary battery according to the present invention has a collector and a negative electrode active material layer formed on a surface of the collector and containing negative electrode active material particles. In the negative electrode active material layer, an insulating material is arranged between the negative electrode active material particles so as not to develop conductivity by a percolation path throughout the negative electrode active material layer. It is possible in this configuration to effectively prevent the occurrence of a short-circuit current due to an internal short circuit and the generation of heat due to such short-circuit current flow in the secondary battery while securing the battery performance of the secondary battery.
