据观察，通过减小SnO颗粒尺寸，同时保持相同的晶粒尺寸，可逆和初始比容量增加。据信，随着颗粒尺寸减小，Li离子插入位点的数量增加，并且Li离子扩散距离因此减小，从而增加初始容量和可逆容量。SnO的可逆比容量达到657 mA h/g，这是迄今为止插入阳极的最高比容量之一。
It was observed that by decreasing the SnO particle size, while maintaining the same grain size, the reversible and initial specific capacities increased. It is believed that as the particle size decreases the number of Li-ion insertion sites increase and Li-ion diffusion distances decrease thus, increasing both the initial and reversible capacities. A reversible specific capacity of 657 mA h/g was achieved for SnO, which is one of the highest to date for insertion anodes.
