Abstract An improved precipitation method - electrostatic spray precipitation is proposed, which is characterized by introducing the electrostatic atomization effect into the precipitation process. The results display that electrostatic atomization can effectively reduce the size of reaction solution droplets under electrostatic force, the growth process of crystal nucleus is optimized, and then flake cluster MnCO3 is obtained, which further promotes the formation of homogeneous MnO nanoparticles. Compared with the agglomerated MnO without electrostatic action, homogeneous MnO nanoparticles exhibit better cycling stability (787 mAh g−1 after 100 cycles at 377.5 mA g−1) and rate capability (471 mAh g−1 at 3020 mA g−1).

静电喷雾沉淀制备的均质MnO纳米颗粒和储锂性能

摘要 提出了一种改进的沉淀法——静电喷雾沉淀法，其特点是在沉淀过程中引入了静电雾化效应。结果表明，静电雾化可以有效减小静电力作用下反应液液滴的尺寸，优化晶核的生长过程，得到片状团簇MnCO3，进一步促进了均质MnO纳米粒子的形成。与没有静电作用的团聚 MnO 相比，均质的 MnO 纳米颗粒表现出更好的循环稳定性（377.5 mA g-1 下 100 次循环后 787 mAh g-1）和倍率性能（3020 mA g-1 下 471 mAh g-1）。
