NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR PRODUCING SAME |
摘要 |
A negative electrode 1 for nonaqueous secondary batteries characterized by having an active material layer 5 and a metallic lithium layer 3 both between a pair of current collecting surface layers 4. The negative electrode 1 has two negative electrode precursors 2 each composed of the current collecting surface layer 4 and the active material layer 5 on one side of the surface layer 4. The two negative electrode precursors 2 are united with their active material layers 5 facing each other and with the metallic lithium layer 3 sandwiched therebetween. A metallic material having low capability of forming a lithium compound penetrates through the whole thickness of the active material layer 5. |
