Abstract A high performance, durable cathode material for lithium ion batteries is achieved by incorporating ∼50 nm Li3V2(PO4)3/C core-shell nanospheres into a porous carbon framework. The Li3V2(PO4)3/C nanocomposite delivers an initial discharge capacity of 130 mA h g(-1), approaching its theoretical limit (133 mA h g(-1)). At a high current rate (10 C), the nanocomposite displays an impressive long cycle life and remarkable capacity retention (90\% after 1200 cycles). Notably, the Coulombic efficiency is above 99\% during the course of cycling. The remarkable power capability and cycle stability derived from our simple and scalable synthesis suggests that this 4 V-class material could be one of the most promising candidates for future batteries.
