Codoping effect of Li1.1V0.9O2 anodes for lithium-ion batteries with Mo and W (Li1.1V0.9−2xMoxWxO2): Based on electronic structure calculations using full-potential KKR-Green's function method

► Discovery on the significant effect of co-doping of W and Mo. ► Capacity of the doped Li1.1V0.9O2 was double higher than that of the bare samples at high C-rate. ► The origin was the increase of electronic conductivity due to the extra free electron by doping.
