| Abstract: | The polyprotic acid H(3)PO(4) in a Li(2)SO(4) supporting electrolyte has been effectively utilized as a catholyte donating three protons in dual-electrolyte Li-air cells. The cell offers a high capacity of 740 mA h g(-1) at an average cell voltage of 3.3 V with good rechargeability and stability. |
