Abstract
A rechargeable lithium battery is disclosed having a positive electrode, a negative electrode and a non-aqueous electrolyte. The positive or negative electrode contains, as its active material, an Li—Ti complex oxide having a spinel crystal structure and represented by the compositional formula Li4MxTi5−xO12, wherein M is at least one element selected from V, Nb, Mo and P and x satisfies the relationship 0<x≦0.45.
