Abstract
The high-rate charging and cycling of Li-ion batteries is improved by blending Li2RuO3 into LiCoO2 cathodes in cells with Li4Ti5O12 anodes. The cathode-limited cells have greater discharge capacities when Li2RuO3-containing cathodes are recharged up to 2C rates. The Li4Ti5O12/Li2RuO3 + LiCoO2 cells also show capacity increases over initial cycles and minimal capacity decay when cycled at a 2C rate over 50 cycles. These benefits are attributed to the reduced cell impedance of the Li2RuO3-containing cathodes.
