Abstract: Novel porous spherical CuO xerogels constructed by crystalline nanorods (100–200nm in length and 20–40nm in diameter) are synthesized as anode materials in lithium-ion batteries. Aided with the soft-template of P123, the product possesses abundant mesopores centered at ~7.3nm and high surface area of 63.1m2 g−1. Benefiting from its structural features, including porous structure, one-dimensional structure, and oriented growth along (111) plane, the presented sample delivers high reversible capacity (646.7mAhg−1 at 0.2C after 150 cycles), excellent cyclic performance (88% capacity retention after 150 cycles), and superior rate capability (510mAhg−1 at 0.5C).
