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.

Claims (13)

1. A metal-ion battery comprising:

(a) an anode;

(b) a cathode; and

(c) a nanoconfined metal-containing electrolyte in contact with said anode and cathode, said nanoconfined metal-containing electrolyte comprising a layer of enclosed nanostructures having a particle size of at least 10 nm and up to 500 nm, wherein each enclosed nanostructure contains a liquid metal-containing electrolyte, wherein said enclosed nanostructures are in physical contact with each other, wherein said enclosed nanostructures contain pores, with at least 90% of the pores having a pore size of up to 6 nm, and wherein said nanostructures are hollow when not filled with the liquid metal-containing electrolyte.

2. The metal-ion battery according to claim 1 , wherein said anode is a metal anode.
