In aqueous electrolyte batteries, the salt concentration of the electrolyte affects the ionic conductivity, which will further affect the rate performance of the battery as well as the diffusion of reactive species that can cause self-discharge, particularly in thick electrode devices. To this end, we explored the implications of device performance using Na 0.44 MnO 2 cathode material, NaTi 2 (PO 4 ) 3 , anode material in a NaClO 4 -based aqueoussolutions with molarities as highas 5…
