A nickel hexacyanoferrate (NiHCF)/carbon composite is prepared to realize reduced structure vacancies and enhanced conductivity simultaneously. The resultant composite as a cathode material exhibits good capacity retentions both for rate capability (93% of that at 0.1 A g⁻¹ for 2 A g⁻¹) and cycle stability (94% after 900 cycles at 0.5 A g⁻¹). This feature is also kept in an aqueous hybrid energy storage device, after coupling with rGO as the anode. After 5000 cycles at 2 A g⁻¹, 94% of the initial capacity is preserved, exhibiting extraordinary stability at high rates.

六氰合铁酸镍/碳复合材料作为高速率，长寿命的阴极材料，用于水性混合能源存储

制备了六氰合铁酸镍（NiHCF）/碳复合材料，可同时实现减少的结构空位和增强的电导率。所得的复合材料作为正极材料在速率能力（对于2 A g ^-1为0.1 A g ^-1时为93％）和循环稳定性（在0.5 A g ^-1下900次循环后为94％）均显示出良好的容量保持率。在与rGO作为阳极耦合之后，该功能也保留在水性混合能量存储设备中。在2 A g ^-1下进行5000次循环后，保留了94％的初始容量，在高速率下表现出非凡的稳定性。
