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.
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.
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.
The transfer of lithium-ion batteries in rechargeable batteries is constrained by the characteristics of the raw materials themselves and the porosity characteristics after demulsification, which is mainly manifested in the technical parameters, that is, the positive ion oxidation-reduction potential.
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.
