摘要:
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 A x M1 n M2 m (CN) y . d(H 2 O), 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.
摘要(中):
提供了一种在过渡金属氰金属(TMCM)阴极电池中循环功率的方法。 该方法提供具有TMCM阴极,阳极和电解质的电池,其中TMCM对应于AxM1nM2m(CN)y.d(H2O)的化学式,其中“A”是碱金属或碱土金属,其中 M1和M2是过渡金属。 该方法使用第一充电电流或更高的电池充电。 响应于充电电流,在阳极的电镀表面上形成覆盖“A”金属的电镀。 响应于电池的放电,从阳极电镀表面去除“A”金属电镀。 一方面,在电池的初始充电中,在阳极电镀表面上形成永久的固体电解质相(SEI)层。 在随后的充放电循环中,永久性SEI层保持覆盖阳极电镀表面。
