Diaphragm is one of the important inner members in the structure of lithium battery. The characteristics of the diaphragm determine the page structure and internal resistance of the rechargeable battery. It immediately endangers the capacity, circulation system and safety factor of the rechargeable battery.
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.
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 routine diaphragm has a general affinity for organic electrolytes, but its good wettability and liquid retention greatly impact the performance of lithium-ion batteries.
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 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.
