Charge/discharge performances and possible reactions of the electrode using PBPy in a three-electrode cell.
(a), Charge/discharge curves of the PBPy-electrode. (b), Cycle-life performance of the PBPy-electrode (○: charge, ♦: discharge). Conditions, electrolyte solution: 1 mol L−1 n-Bu4NPF6/PC, current density: 100 mA g−1, potential range: −1.8-−0.2 V vs. Ag+/Ag. (c), Possible charge/discharge reaction of PBPy.
