A facile and large-scale fluidized bed reaction route was introduced for the first time to prepare crystalline embedded amorphous silicon nanoparticles with an average size of 50 nm as anode materials for lithium-ion batteries. By increasing the operating potential to control the electrochemically active degree, the resulting sample showed excellent cycle stability with a high capacity retention of 94.7% after 200 cycles at 1 A g⁻¹ in the voltage range of 0.12–2.00 V.

流化床反应对晶体嵌入非晶硅阳极的循环稳定性大大提高†

首次引入一种简便而大规模的流化床反应路线，以制备平均粒径为50 nm的晶体嵌入非晶硅纳米颗粒作为锂离子电池的负极材料。通过增加控制电化学活性程度的操作电位，所得样品显示出出色的循环稳定性，在0.12–2.00 V的电压下，在1 A g ^-1下进行200次循环后，具有94.7％的高容量保持率。
