Abstract
A system and method for optimizing electrochemical cells including electrodes employing coordination compounds by mediating water content within a desired water content profile that includes sufficient coordinated water and reduces non-coordinated water below a desired target and with electrochemical cells including a coordination compound electrochemically active in one or more electrodes, with an improvement in electrochemical cell manufacture that relaxes standards for water content of electrochemical cells having one or more electrodes including one or more such transition metal cyanide coordination compounds.
Claims20
An electrochemical structure, comprising:
- an electrochemical assembly having a liquid anhydrous electrolyte, a first electrode, a separator, and a second electrode, at least one of said electrodes electrochemically communicated with said liquid anhydrous electrolyte;
- wherein said at least one of said electrodes includes a hydrated transition metal cyanide coordination compound material having a composition conforming to formula I, formula I including AxPy[R(CN)6]z(H2O)n;
- wherein A identifies as one or more alkali cations and P and R each represent one or more divalent or trivalent transition metal cations;
- wherein 0.5<z<1;
- wherein x, y, and z are related based on electrical neutrality, x>0, y>0, z>0;
- and
- wherein n=6*(1−z)+m, and wherein n>0;
