摘要

The high-rate charging and cycling of Li-ion batteries is improved by blending Li_2RuO_3 into LiCoO_2 cathodes in cells with Li_4Ti_5O_(12) anodes. The cathode-limited cells have greater discharge capacities when Li_2RuO_3-containing cathodes are recharged up to 2C rates. The Li_4Ti_5O_(12)/Li_2RuO_3 +LiCoO_2 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 Li_2RuO_3-containing cathodes.
