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.
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 .
