Porous olive-like carbon decorated Fe 3 O 4 based additive-free electrodes for highly reversible lithium storage

Additive-free porous olive-like carbon decorated Fe 3 O 4 directly synthesized on the current collectors by centrifugation assisted deposition were developed. Excellent cycling performance was achieved with a specific capacity at ∼800 mA h g −1 for at least 235 cycles and impressive rate performance was accomplished.
