The 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.
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 .
The lithium-ion migration numbers of ZnB modified diaphragm are 0.41, while the lithium-ion migration numbers of ZnO modified diaphragm and routine diaphragm are 0.3 and 0.21. When the battery is working, the charge transfer rate of lithium ions reflects the charging and discharging characteristics of the battery.
Therefore, the composite diaphragm can store more electrolytes under the same volume. Zinc borate has the synergistic effect of boric acid groups and polar metal bonds, which promotes the transmission of lithium ions in the electrode, thereby increasing the conductivity of lithium ions.
Because the zinc borate coating has better electrolyte affinity and liquid retention ability, the impedance of the diaphragm and the positive electrode interface is reduced, which helps lithium ions to migrate through the interface between the electrode and the diaphragm. This is helpful in increasing the specific discharge capacity of the battery.
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.
