We report the excellent charge storage performance of high-energy Li-ion capacitors (LIC) fabricated from the mesoporous Co 3 O 4 nanosheets as the conversion-type battery component and Jack fruit ( Artocarpus heterophyllus ) derived activated carbon as a supercapacitor electrode, especially at high temperatures (50 and 40 °C). Prior to the fabrication, the electrochemical prelithiation strategy was applied to Co 3 O 4 to alleviate the irreversibility and enrich the Li-ions for electrochemical reactions (Co 0 + Li 2 O). The LIC delivered a maximum energy density of ∼118 Wh kg -1 at a high temperature of 50 °C. The significant difference is observed at a high rate of 2.6 kW kg -1 at 50 °C with excellent cycle stability up to 3000 cycles, with a retention of ∼87% compared with the LIC cycled at room temperature (∼74%). The magnificent electrochemical performance clearly demonstrates that the mesoporous structure and residual carbon synergistically facilitated the Li + /electron transport and hinder undesirable side reactions with electrolytes to realize high-energy density at high temperatures. |
