spherical diffusion meaning in Chinese

球面扩散

The effects of the fabrication conditions on the crystal structure , grain size , micromorphology and electrochemical performance of these materials have been studied in depth . the reaction mechanism of the low - heating solid - state reaction method has also been investigated . in addition , a novel electrochemical method ( rpg method ) based on the concept of " ratio of potentio - galvano - charge capacity " has been for the first time developed to determine the diffusion coefficient of lithium - ion within insertion - host materials on the basis of the spherical diffusion model
本论文较系统地考察了低热固相反应法合成锂离子电池正极材料的可行性问题，研究了工艺条件对材料的晶体结构、晶粒尺寸、微观形貌及电化学性能等的影响，探讨了低热固相反应的机理，并通过引进“恒压-恒流充电容量比”的概念，给出了一种测定锂离子嵌入脱出固相扩散系数的新方法。
