Dye-sensitized photorechargeable batteries (DSPBs) have recently gained attention for realizing energy recycling systems under dim light conditions. However, their performance high storage efficiency (i.e., the capacity charged within a limited time) practical application remains to be evaluated. Herein, we varied lithium (Li)-ion concentration, which plays dual role as charging and components, obtain optimized density of DSPBs. Electrochemical studies showed that Li-ion concentration strongly affected resistance characteristics In particular, increasing improved output decreased voltage. Consequently, finely DSPB from 8.73 12.64 mWh/cm3 when irradiated by 1000-lx indoor light-emitting-diode lamp. These findings on effects concentrations in electrolytes DSPBs represent step forward
