Japanese Patent JP7211470

B2

To provide an electrolyte precursor solution that can reduce the grain boundary resistance on the interface between an active material particle and an electrolyte to form an electrolyte indicating excellent ionic conductivity, and a method for manufacturing an electrode complex, an electrode complex, and a battery using the same.SOLUTION: An electrolyte precursor solution includes a metal compound that includes elements constituting an electrolyte, a solvent that can dissolve the metal compound, and an anionic surfactant 25 in which a sulfate group (SO42-) is coupled to a hydrophobic group. When such an electrolyte precursor solution is reacted with an active material particle 11a including lithium, lithium sulfate derived from the anionic surfactant can be included in the interface between the surface of the active material particle 11a and the electrolyte, dissociation of lithium ions on the interface can be accelerated, and excellent ionic conductivity can be achieved.SELECTED DRAWING: Figure 8
