Description

金属Ｍの表面に固着させる金属Ｒとしては、リチウムと電気化学的に反応しない金属であればどのようなものでも使用可能であるが、具体的にはＣｒ、Ｍｎ、Ｆｅ、Ｃｏ、Ｎｉ、Ｃｕ、Ｍｏ、Ｎｂ、Ｎｄ、Ｓｍ、Ｔａ、Ｔｉ、Ｖ等の金属が挙げられる。また、金属Ｒは必ずしも元素単体である必要はなく、合金、金属間化合物であっても構わない。また、それらを２種以上混合することも可能である。つまり、金属Ｒはリチウムと電気化学的に反応せず、電子伝導性を有するものであればどのようなものでも好適に使用可能である。   As the metal R fixed to the surface of the metal M, any metal that does not electrochemically react with lithium can be used. Specifically, Cr, Mn, Fe, Co, Ni, Cu , Mo, Nb, Nd, Sm, Ta, Ti, V, and other metals. Further, the metal R does not necessarily need to be a single element, and may be an alloy or an intermetallic compound. Moreover, it is also possible to mix 2 or more types of them. In other words, any metal R that does not react electrochemically with lithium and has electronic conductivity can be suitably used.
