TiNb2O7 anode for high energy and power Li-ion hybrid electrochemical capacitor

Green Car Congress

Researchers in Singapore report the first use of TiNb 2 O 7 as an insertion-type anode in a lithium-ion hybrid electrochemical capacitor (Li-HEC) along with an activated carbon (AC) counter electrode derived from a coconut shell. The Li-HEC delivers very high energy and power densities of approximately 43?Wh? kg -1 and 3?kW
