A system and method implementing and manufacturing transition metal cyanide coordination compounds (TMCCC) comprising Na, Fe, Mn, C, H, N, S, and O, wherein the TMCCC have 0-14% hexacyanometallate vacancies such as for application in electrochemical cells, including sodium ion secondary batteries.

Low vacancy Fe-substituted Mn-based prussian blue analogue

A system and method for a liquid electrolyte used in secondary electrochemical cells having at least one electrode including a TMCCC material, the liquid electrolyte enabling an increased lifetime while allowing for fast discharge to extremely high depth of discharge. The addition of dinitriles to liquid electrolytes in electrochemical cells in which energy storage is achieved by ion intercalation in transition metal cyanide coordination compounds (TMCCC) has the advantage of increasing device lifetime by inhibiting common chemical and electrochemical degradation mechanisms.

Electrochemical cell with TMCCC electrodes in an acetonitrile solvent including a dinitrile additive

A system and method implementing and manufacturing transition metal cyanide coordination compounds (TMCCC) comprising Na, Fe, Mn, C, H, N, S, and O, wherein the TMCCC have 0-14% hexacyanometallate vacancies such as for application in electrochemical cells, including sodium ion secondary batteries; further including both sodium and potassium with and without sulfate.

A system and method for implementing and manufacturing a hierarchy system for use with a TMCCC-containing electrically-conductive structure (e.g., an electrode) as well as methods for use and manufacturing of such structures and electrochemical cells including these devices. Structures and methods include a coordination complex having LMNTiVCrMnFeCoNiCuZnCaMg[R(CN)](HO). The method includes binding electrochemically active material to produce a hierarchical structure, the hierarchical structure having a plurality of primary crystallites having a size D1, the plurality of these primary crystallites agglomerated into a set of agglomerates each agglomerate having a size D2>D1.

Hierachical structure of transition metal cyanide coordination compounds

An electrochemical cell having one or more electrodes with TMCCC materials introduces improved performance by including a special separator having ceramics and/or a discrete multilayer construction. TMCCC materials with no surface modifications, and existing electrolytes with no composition modifications are combined with a different grade of separator to improve cell performance.

Separator for electrochemical cell

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.
