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.

An apparatus for manufacturing an electrode assembly includes a separator supply unit, table, separator guide, first adhesive supply unit, and pair of tensioners. The separator supply unit is configured for supplying a separator sheet from which a separator is formed. The table is configured for supporting electrodes and sections of the separator sheet. The separator guide is configured for guiding the separator sheet to fold in a particular folding direction. The first adhesive supply unit is configured for applying an adhesive to portions of the separator sheet and the electrodes supported by the table. The pair of tensioners are each configured for pressing an uppermost section of the separator sheet guided by the separator guide against the table or against a placed electrode that directly underlies the uppermost section. The electrode assembly is manufactured by a process using the apparatus.

An electrode assembly includes a stack, in which a plurality of electrodes and a plurality of separators are alternately stacked on each other and edges of the separators protrude further outward than the electrodes, and a wrapping separator, which surrounds the stack. The edges of at least some of the plurality of separators may be fused with the wrapping separator to form fused portions.

A method comprises obtaining a stack for an energy storage device, the stack comprising a first electrode layer and an electrolyte layer. The method comprises depositing a first material over an exposed portion of the first electrode layer and an exposed portion of the electrolyte layer. The method comprises depositing a second material over the first material and to form a second electrode layer of the stack, and to provide an electrical connection from the second electrode layer, for connecting to a further such second electrode layer via the second material. The electrolyte layer is between the first electrode layer and the second electrode layer. The first material insulates the exposed portions of the first electrode layer and the electrolyte layer from the second material. Also disclosed is an apparatus for maintaining top-down inkjet material deposition.
