MIT team synthesizes all carbon nanofiber electrodes for high-energy rechargeable Li-air batteries

Green Car Congress

Gravimetric Ragone plot comparing energy and power characteristics of CNF electrodes based on the pristine and discharged electrode weight with that of LiCoO 2. This translates to an energy enhancement ~4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO 2 (~600 W h kg electrode -1 , the researchers said.
