Bismuth oxyfluoride impregnated CMK-3 nanocomposite is synthesized by a facile nanocasting approach. Mesoporous carbon CMK-3 can suppress the aggregation and growth of bismuth oxyfluoride particles and offer rapid electron and Li ion passageways. Bismuth oxyfluoride nanoparticles are embedded in the mesoporous channels with particle size less than 20 nm. The bismuth [email protected] nanocomposite maintains 148 mA h g⁻¹ after 40 cycles with the capacity from both the bismuth oxyfluoride and the functional groups on the mesoporous carbon. The hybrid with confined bismuth oxyfluoride nanoparticles, conductive carbon network, and oxygen functional groups on the carbon matrix exhibits higher capacity and cycling stability than bulk bismuth oxyfluoride particles when used as lithium ion batteries cathode.

氟氧化铋浸渍的CMK-3纳米复合材料是通过一种简便的纳米浇铸方法合成的。介孔碳CMK-3可以抑制氟化氧铋颗粒的聚集和生长，并提供快速的电子和锂离子通道。氟氧化铋纳米粒子嵌入尺寸小于20 nm的中孔通道中。铋（受电子邮件保护的）纳米复合材料在40个循环后保持148 mA h g ^-1的容量，同时具有氟化氧铋和中孔碳上的官能团的容量。当用作锂离子电池阴极时，具有受限的氟氧化铋纳米粒子，导电碳网络和碳基团上的氧官能团的杂化物比块状氟氧化铋粒子具有更高的容量和循环稳定性。
