Abstract
A nanoconfined metal-containing electrolyte comprising a layer of enclosed nanostructures in which each enclosed nanostructure contains a liquid metal-containing electrolyte, wherein said enclosed nanostructures are in physical contact with each other. Metal-ion batteries containing the nanoconfined electrolyte in contact with an anode and cathode of the battery are also described. Methods for producing the nanoconfined electrolyte are also described.
Claims10
A method for producing a nanoconfined metal-containing electrolyte, the method comprising:
- (i) forming a layer of hollow enclosed nanostructures having a particle size of at least 10 nm and up to 500 nm, wherein the hollow enclosed nanostructures are in physical contact with each other, wherein said hollow enclosed nanostructures contain pores, with at least 90% of the pores having a pore size of up to 6 nm;
- and
- (ii) loading the hollow regions of said hollow enclosed nanostructures with a liquid metal-containing electrolyte by infusion of said liquid metal-containing electrolyte through walls of said hollow enclosed nanostructures to produce the nanoconfined metal-containing electrolyte, wherein said nanostructures are hollow when not filled with the liquid metal-containing electrolyte.
