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。
And a intelligent battery management system with full functions has been designed , which improved the management of charge and the estimation of residual capacity . the paper changed the current value of constant current charge - state , which current seems not constant during the working time , based on the three mice laws about battery charge . this change would increase the speed of charge , without harm to the battery 同时本论文还设计了一套功能齐备的蓄电池智能管理系统，针对蓄电池管理中的充电管理和剩余时间预测进行了改进，提出：在恒流充电时，根据麦斯三大定律，改变恒流充电时的恒流值，使恒流充电“不恒流” ，而是根据放电的不同情况进行充电，充分提高充电速度，同时又不损伤电池活性物质；不再进行剩余容量预测，而是进行剩余时间预测，提供更加切实可行的信息，并且提出了一种简单易行的剩余时间预测的方法，给出了预测实验的结果。
