A one-step and energy-saving method was proposed to synthesize hierarchical and hollow Co(VO)-Co(OH) composite leaf arrays on carbon cloth, which expressed high capacitance (522 mF cm or 803 F g at the current density of 0.5 mA cm), good rate capability (79.5% capacitance retention after a 30-fold increase of the current density) and excellent cycling stability (90% capacitance retention after 15 000 charge-discharge cycles) when tested as a supercapacitor electrode.
提出了一种一步法和节能的方法，在碳布上合成了分级和中空的 Co(VO)-Co(OH) 复合叶状阵列，其表现出高电容（在电流密度为 0.5 mA cm 时为 522 mF cm 或 803 F g）、良好的倍率性能（在电流密度增加 30 倍后电容保持率为 79.5%）和优异的循环稳定性（在 15000 次充放电循环后电容保持率为 90%），可用作超级电容器电极。
