Self-supporting Co3O4 with lemongrass-like morphology as a high-performance anode material for lithium ion batteries

Self-supporting Co3O4 with lemongrass-like morphology exhibits excellent rate capability and cyclic stability for high-performance Li ion batteries as electrodes. It retains a high reversible capacity of up to 981 mA h g−1 after 100 cycles at a rate of 0.5 C and a capacity higher than 381 mA h g−1 even at a rate as high as 10 C.
