In recent years, as a flexible electrode material, melamine foam has attracted more and more attention from researchers in the field of wearable energy storage devices. In addition, certain components are loaded on it to improve electrochemical performance and further promote its advantages. Here, we first carbonized commercial melamine foam in N₂ atmosphere to form in situ doping and then used a simple hydro-thermal reaction to uniformly load MnO₂ nanosheet arrays on its three-dimensional framework. For the resulting electrode material, the specific capacitance was as high as 230.3 F/g under the current density of 1 A/g. With the voltage window of 0–2.2 V, the energy density of the assembled quasi-solid supercapacitor reached 29.73 Wh/kg with the power density of 1636.9 W/kg, showing great electrochemistry performance and application prospects.

近年来，作为一种柔性电极材料，三聚氰胺泡沫越来越受到可穿戴储能设备领域研究人员的关注。此外，在其上加载某些成分以提高电化学性能并进一步发挥其优势。在这里，我们首先在 N ₂气氛中碳化商业三聚氰胺泡沫以形成原位掺杂，然后使用简单的水热反应均匀负载 MnO ₂纳米片阵列在其三维框架上。对于所得电极材料，在 1 A/g 的电流密度下，比电容高达 230.3 F/g。在0-2.2 V的电压窗口下，组装的准固态超级电容器的能量密度达到29.73 Wh/kg，功率密度为1636.9 W/kg，显示出良好的电化学性能和应用前景。
