摘要：
A negative electrode active material contains a metal-displaced lithium-titanium oxide of a ramsdellite structure expressed by the formula Li(16/7)-xTi(24/7)-yMyO8 (where M is at least one metal element selected from the group consisting of Nb, Ta, Mo, and W, and x and y are respectively numbers in the range of 0
