Abstract

In situ self-catalyzed core-shell LiFePO₄@CNT nanowires can be fabricated by a two-step synthesis, where one-dimensional LiFePO₄ nanowires with a diameter of 20-30 nm were encapsulated into CNTs, and 3D conducting networks of CNTs were obtained from in situ carbonization of a polymer. LiFePO₄@CNT nanowires deliver a capacity of 160 mA h g ^-1 at 17 mA g^-1, and 65 mA h g^-1 at 8500 mA g^-1 (50 C, 1.2 minutes for charging and 1.2 minutes for discharging).
