Abstract
The feasibility of using iron oxides as negative electrode materials for safe high-power Li-ion batteries is demonstrated by the carbon-coated FeOx/CNT composite synthesized by controlled pyrolysis of ferrocene, which delivered a specific capacity retention of 84% (445 mA h g(-1)) after 2000 cycles at 2000 mA g(-1) (4C).
Highlights
Demonstrating the steady performance of iron oxide composites over 2000 cycles at fast charge-rates for Li-ion batteries
We demonstrate the feasibility of using iron oxides as negative electrode materials for safe high-power Li-ion batteries by the carbon-coated FeOx/carbon nanotube (CNT) composite
