Abstract
A method is provided for cycling power in a transition metal cyanometallate (TMCM) cathode battery. The method provides a battery with a TMCM cathode, an anode, and an electrolyte, where TMCM corresponds to the chemical formula of AM1M2(CN)-d(HO), where 'A' is an alkali or alkaline earth metal, and where M1 and M2 are transition metals. The method charges the battery using a first charging current, or greater. In response to the charging current, a plating of 'A' metal is formed overlying a plating surface of the anode. In response to discharging the battery, the “A” metal plating is removed from the anode plating surface. In one aspect, in an initial charging of the battery, a permanent solid electrolyte interphase (SEI) layer is formed overlying the anode plating surface. In subsequent charging and discharging cycles, the permanent SEI layer is maintained overlying the anode plating surface.
