Negative electrode for secondary battery

摘要

A negative electrode for a secondary battery which has a positive electrode including a polymer active material. The negative electrode includes: a current collector beforehand roughened at one surface thereof; a first layer disposed on the roughened one surface and including a material selected from the group consisting of alkali metal and an alloy containing alkali metal; and a second layer disposed on the first layer and including an ion conductive material. A surface of the first layer has an uneven configuration which conforms with another uneven configuration of the roughened one surface of the current collector, the surface of the first layer being in contact with the second layer. A method for manufacturing the negative electrode is also disclosed.
