摘要
采用快速一步熔盐法合成了柔性准固体对称超级电容器Mn3O4@CC电极。Mn3O4在高极性熔盐体系中生长迅速，并牢固地锚定在碳布上。熔盐法可以实现钠嵌入Mn3O4，从而提高其电导率和电容量。结果表明，na -0.9基超级电容器在5ma cm - 2时具有1225.7 mF cm - 2的高电容。本文所提出的制备方法、组合物结构设计策略将为实现高性能柔性超级电容器提供一条新的途径。
Synthesis of Mn3O4 on carbon cloth for flexible supercapacitors
Mn3O4@CC electrodes were synthesized via a fast one-step molten salt method for flexible quasi-solid symmetric supercapacitors. Mn3O4 grows rapidly in a high polarity molten salt system and strongly anchors to carbon cloth. The molten salt method can realize sodion embedded in Mn3O4 and then improve the conductivity and capacitance. The results show that the Na-0.9-based supercapacitor exhibits a high capacitance of 1225.7 mF cm−2 at 5 mA cm−2. The preparation method, design strategy on structure of composition in this work will provide a novel route to realize high-performance flexible supercapacitors.
