A bamboo powder-derived porous carbon-supported ZnO composite was successfully applied as an anode for the lithium-ion capacitor (LIC), while the obtained porous foam carbon by acid washing was used as a cathode. The LIC showed excellent electrochemical performance with high energy density, power density, and cycling stability. This study demonstrates the great potential of bamboo as a high-performance carbon material for energy storage applications.
The lithium-ion capacitor (LIC) is developed for advanced energy reserve systems, which can fulfill the requirements of long cycling capability and high power and energy density. Herein, a bamboo powder-derived porous carbon-supported ZnO composite (denoted as CZK1) was prepared and applied as an anode for the LIC. The obtained porous foam carbon (denoted as BLZACK1) acquired by acid washing of CZK1 was used as a cathode for the LIC. The assembled CZK1//BLZACK1 LIC by using CZK1 and BLZACK1 as the anode and cathode, respectively, exhibited excellent electrochemical performance. It possesses a high energy density of 134.98 W h kg(-1) with a power density of 9793.58 W kg(-1). Besides, after 8000 cycles at 5 A g(-1), the capacitance retention is 83.90%, suggesting its outstanding cycling stability. This study shows that bamboo can be used as a derived highperformance carbon material with great potential in the field of energy storage.
