Highly improved aqueous Zn‖LiMn2O4 hybrid-ion batteries using poly(ethylene glycol) and manganese sulfate as electrolyte additives

Using a low dosage of poly(ethylene glycol) and MnSO 4 for co-filling a bisalt electrolyte efficiently enhances the charging/discharging cycling performance of aqueous Zn‖LiMn 2 O 4 batteries at relatively low current densities.
