A LiCoPO4/Li4Ti5O12 battery prototype is designed to fully take profit of high energy density of LiCoPO4 and superior reliability of Li4Ti5O12. Electrochemical test results show that the battery affords an operational voltage of 3.2 V and delivers a reversible capacity of 122 mAh g(-1). Based on the mass of LiCoPO4, the energy density of such a battery can reach 378 mWh g(-1). Provided the long-term cyclability of the LiCoPO4 cathode could be well addressed, this LiCoPO4/Li4Ti5O12 system offers an alternative for large-scale energy storage application.
