Preparing spherical particles with carbon additive is considered as one effective way to improve both high rate performance and tap density of Li4Ti5O12 and LiFePO4 materials. Spherical Li4Ti5O12/C and LiFePO4/C composites are prepared by spray-drying–solid-state reaction method and controlled crystallization–carbothermal reduction method, respectively. The X-ray diffraction characterization, scanning electron microscope, Brunauer–Emmett–Teller, alternating current impedance analyzing, tap density testing, and electrochemical property measurements are investigated. After hybridizing carbon with a proper quantity, the crystal grain size of active materials is remarkably decreased and the electrochemical properties are obviously improved. The Li4Ti5O12/C and LiFePO4/C composites prepared in this work are spherical. The tap density and the specific surface area are as high as 1.71 g cm−3 and 8.26 m2 g−1 for spherical Li4Ti5O12/C, which are 1.35 g cm−3 and 18.86 m2 g−1 for spherical LiFePO4/C powders. Between 1.0 and 3.0 V versus Li, the reversible specific capacity of the Li4Ti5O12/C is more than 150 mAh g−1 at 1.0-C rate. Between 2.5 and 4.2 V versus Li, the reversible capacity of the LiFePO4/C is close to 140 mAh g−1 at 1.0-C rate.
