In this manuscript, we provided a new synthetic method to conveniently synthesize the mesoporous carbon platelets of high surface area (>1,000 m²/g), large pore size (≈8.0 nm), and short channel length (<100 nm) for the application in high‐power supercapacitor. A co‐assembly approach to prepare the phenol formaldehyde‐Pluronic F127‐calcium phosphate composite was proposed. In such composites, the PF‐F127 organic parts occluded within the Ca₃(PO₄)₂ crystals can be converted to mesoporous carbon platelets and the calcium phosphate is easily removed in an acidic aqueous solution rather than using a highly corrosive HF solution for silica removal. In practice, the platelets of relatively large mesopores, short pore channels, high specific surface area, and good electronic conductivity to meet the high power demands. It shows that the mesoporous carbon can have a rectangle‐like shape i‐E curve measured at a very high scan rate of 4,000 mV/s in 4.0 M H₂SO₄. The novel mesoporous carbon platelets electrode exhibits only 29% loss when the scan rate is varied from 100 to 4,000 mV/s. The above perfect capacitive performances confirm the promising applicability of this novel mesoporous carbon for supercapacitors of ultrahigh power.

由高功率超级电容器用聚合物共混物-磷酸钙纳米复合材料合成高表面积和大孔隙率的中孔碳片

在本文中，我们提供了一种新的合成方法，可以方便地合成高表面积（> 1,000 m ² / g），大孔径（≈8.0nm）和短通道长度（<100 nm）的中孔碳血小板。在大功率超级电容器中的应用。提出了一种共组装法制备酚醛-Pluronic F127-磷酸钙复合材料。在这种复合材料中，PF-F127有机物被堵塞在Ca ₃（PO ₄）_2内晶体可以转化为中孔碳片，磷酸钙很容易在酸性水溶液中除去，而不是使用高腐蚀性的HF溶液除去二氧化硅。实际上，具有相对较大的中孔，短的孔通道，高的比表面积和良好的电导率的血小板可以满足高功率需求。结果表明，中孔碳可以在4.0 MH ₂ SO _4中以4,000 mV / s的极高扫描速率测量，呈矩形的i ‐ E曲线。。当扫描速率从100到4,000 mV / s变化时，新型中孔碳血小板电极仅表现出29％的损耗。上述完美的电容性能证实了这种新型介孔碳在超高功率超级电容器中的应用前景。
