Customer ServiceThe diaphragm of a lithium-ion battery has important functions, such as preventing a short circuit between the positive and negative electrodes of the battery and improving the movement channel for electrochemical reaction ions.
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 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).
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. So they can be improved that the ordinary diaphragm's physical and chemical properties.
The multifunctional diaphragms modified by zinc borate have the following advantages: (1) The Zn–O bond and -BO 3 group in the structure have a polar bond and Lewis acid action, respectively, which can promote the desolvation of lithium ions and the dissociation of anions and cations, thereby increasing the concentration of free ions.
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.
