摘要：

The electrochemistry of the Zn-VPO4F system has been studied for the first time in both wet non-aqueous and aqueous zinc-ion electrolytes. It is shown that H+ ions present in the electrolyte insert into the cathode host in preference to sluggish Zn2+ ion insertion. Furthermore, it is demonstrated that while H2O as a source of H+ is essential for proper cell operation, an aqueous electrolyte is detrimental to cathode stability due to extensive dissolution.
