In situ transmission electron microscopy (TEM) is used to study the electrochemical lithiation of high-capacity crystalline Si nanoparticles for use in Li-ion battery anodes. The lithiation reaction slows down as it progresses into the particle interior, and analysis suggests that this behavior is due not to diffusion limitation but instead to the influence of mechanical stress on the driving force for reaction.
原位透射电子显微镜（TEM）用于研究用于锂离子电池阳极的高容量结晶硅纳米颗粒的电化学嵌锂。随着嵌锂反应的进行，反应速度会减慢，分析表明这种行为不是由于扩散限制，而是由于机械应力对反应驱动力的影响。
