Figure 6. Electrochemical performance of acid-only and pH-asymmetric Sn-Br full cells Charge/discharge profiles of (A) the acid-only full cell and (B) the acid-alkaline pH-asymmetric full cell at a current density of 3 A g^-1; (C) Long-term cycling performance of the acid-only and pH-asymmetric full cells at 3 A g^-1; (D) Performance comparison of the pH-asymmetric Sn-Br full cell with previously reported bromine-based batteries (detailed electrolyte compositions, electrode materials, and test conditions are provided in Table 1).
