Abstract
Official abstract text for this publication.
Battery electrode compositions are provided for use in aqueous electrolytes and may comprise, for example, a current collector, active particles, and a conformal, metal-ion permeable coating. The active particles may be electrically connected to the current collector, and provided to store and release metal ions of an active material during battery operation. The conformal, metal-ion permeable coating may at least partially encase the surface of the connected active particles, whereby the conformal, metal-ion permeable coating impedes (i) direct electrical contact of an aqueous electrolyte with the active particles and (ii) aqueous electrolyte decomposition during battery operation. Such electrode compositions and corresponding aqueous batteries may facilitate the incorporation of advanced material synthesis and electrode fabrication technologies, and enable fabrication of high voltage and high capacity aqueous batteries at a cost lower than that of conventional metal-ion battery technology.
First claim

1 . A battery electrode composition for use in aqueous electrolytes, comprising: a current collector; active particles electrically connected to the current collector, wherein the active particles are provided to store and release metal ions of an active material during battery operation; and a conformal, metal-ion permeable coating that at least partially encases the surface of the connected active particles, whereby the conformal, metal-ion permeable coating impedes (i) direct electrical contact of an aqueous electrolyte with the active particles and (ii) aqueous electrolyte decomposition during battery operation. 2 . A method of fabricating an aqueous metal-ion battery electrode composition, comprising: providing active particles to store and release metal ions of an active material during battery operation; electrically connecting the active particles with a current collector; and forming a conformal, metal-ion permeable coating so as to at least partially encase the surface of the connected active particles.
