The routine diaphragm has a general affinity for organic electrolytes, but its good wettability and liquid retention greatly impact the performance of lithium-ion batteries.
A simple sol-gel coating method is used to uniformly deposit a thin layer of titanium dioxide on the PP diaphragm. The LiFePO 4 /Li battery with PP@TiO 2 diaphragm has a high capacity of 92.6 mAh g −1 at 15C . Gu et al. used nano-ZnO to prepare a new type of porous cross-linked diaphragm.
The LiFePO 4 /Li battery with composite diaphragm exhibits excellent rate and cycle performance. Due to the unique chemical structure of zinc borate, the Zn–O bond and -BO 3 group in the structure have a polar bond and Lewis acid action, respectively.
The zinc borate modified diaphragm was used as the structural-functional ceramic composite diaphragm, and the zinc borate and PVDF were prepared at a mass ratio of 90:10, and the ordinary diaphragm and the zinc oxide modified diaphragm were used as comparison samples. The battery electrolyte was 1 M LiPF6 in EC/DEC (1:1 vol ratio).
The results show that the zinc borate modified diaphragm increases the lithium-ion migration number of the battery. This is because the Lewis acid sites of zinc borate can absorb anions in the battery system, and the increase in the migration number of lithium ions will help improve rate performance .
Therefore, the research on the diaphragm is an important direction related to the performance of the lithium-ion battery. In recent years, the functional design of the diaphragm is usually the method of surface modification of the common diaphragm, adding the intermediate layer and self-constructing the diaphragm, etc.
