Abstract

Cr-Doped Li₂RuO₃ of the Li₂Ru_1−xCr_xO₃ (x = 0, 0.02, 0.05, 0.1) series was successfully synthesized and the effect of Cr on the electrochemical performance of Li₂RuO₃ was systematically investigated. The results show that Li₂Ru_0.95Cr_0.05O₃ exhibits the best performance in terms of capacity, rate capability and cycling stability.
