  • Solid electrolyte, electrode, power storage device, and method for producing solid electrolytes
    Patent number: 11777143
    Abstract: A solid electrolyte of the present disclosure includes: a porous dielectric having a plurality of pores interconnected mutually; and an electrolyte including a metal salt and at least one selected from the group consisting of an ionic compound and a bipolar compound and at least partially filling an interior of the plurality of pores. Inner surfaces of the plurality of pores of the porous dielectric are at least partially modified by a functional group containing a halogen atom.

  • Solid electrolyte, electrode, power storage device, and method for producing solid electrolytes
    Patent number: 11710850
    Abstract: A solid electrolyte (10) of the present disclosure includes porous silica (11) having a plurality of pores (12) interconnected mutually and an electrolyte (13) coating inner surfaces of the plurality of pores (12). The electrolyte (13) includes 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide represented by EMI-TFSI and a lithium salt dissolved in the EMI-TFSI. A molar ratio of the EMI-TFSI to the porous silica (11) is larger than 1.5 and less than 2.0.

  • Solid electrolyte, electrode, and power storage device
    Patent number: 11081685
    Abstract: A solid electrolyte (10) of the present disclosure includes: a porous dielectric (11) having a plurality of pores (12) interconnected mutually; an electrolyte (13) including a metal salt and at least one selected from the group consisting of an ionic compound and a bipolar compound, the electrolyte (13) at least partially filling an interior of each of the plurality of pores (12); and a surface adsorption layer (15) adsorbed on inner surfaces of the plurality of pores (12) to induce polarization. The surface adsorption layer (15) may include water adsorbed on the inner surfaces of the plurality of pores (12). The surface adsorption layer (15) may include a polyether adsorbed on the inner surfaces of the plurality of pores (12).
