摘　　要：使用化学活化法(KOH)制备一种新型的核桃壳生物质炭基电极材料,并组装成水系锌离子混合电容器(Zn-HPC)。研究发现,KOH对核桃壳生物质多孔炭材料电化学性能有较大改善,所组装的核桃壳炭基水系锌离子混合电容器在10000圈的循环后仍具有71.3%的电容保持率和良好的循环稳定性,在未来的储能应用中具有很好的应用前景。A novel walnut shell biomass charcoal-based electrode material is prepared using the chemical activation method(KOH)and is assembled into aqueous zinc ion hybrid capacitors(Zn-HPC).The results show that KOH improves the electrochemical properties of walnut shell biomass porous carbon materials,and the assembled walnut shell carbon based aqueous zinc ion hybrid capacitors still have 71.3%capacitance retention and good cycling stability after 10000 cycles,which are highly promising for future energy storage applications.
