Abstract: An electrode for an electrochemical device includes a neutralizing dispersant; and a complex oxide (A) capable of occluding and releasing lithium ions, wherein the neutralizing dispersant contains: a water-soluble compound (B?) containing a group 13 element (B) of the periodic table; and at least one water-soluble polymer (C) selected from the group consisting of an alkali metal salt, alkaline-earth metal salt, or ammonium salt of alginic acid, methylcellulose, carboxymethyl cellulose, carboxymethyl starch, or carrageenan, pullulan, guar gum, and xanthan gum, a film of the water-soluble polymer (C) is formed on a surface of the complex oxide (A), and the group 13 element (B) of the periodic table is present in the film of the water-soluble polymer (C).

Abstract: The present invention provides an electrolyte which is capable of retaining a high magnesium ion concentration. An electrolyte in accordance with an aspect of the present invention is obtained by mixing a solvent, metal magnesium, and an elemental halogen.

Abstract: An aspect of the present invention provides a binder which makes it possible to obtain an electrode excellent in heat resistance. The binder contains: a re-emulsifiable resin powder coated with inorganic particles; and a metal-crosslinking thickening agent forming a hydrophobic gel by being crosslinked, in an aqueous system, via metal ions derived from an electrode active material.

Abstract: Provided is a binder that makes it possible to prepare a slurry for an electrode with use of water as a solvent and without causing alkalinization of the slurry for the electrode, even in a case where an electrode active material that is highly prone to hydrolysis is used. The binder contains: a pH adjustment functional agent which neutralizes a base in an aqueous system; and a metal-crosslinking thickening agent forming a hydrophobic gel by being crosslinked, in the aqueous system, via metal ions derived from an electrode active material.
