Abstract

Provided is a hybrid solid electrolyte comprising: a hybrid film including (i) 60 to 100 parts by weight of an ion conductive ceramic and (ii) 1 to 40 parts by weight of a polymer; and a liquid electrolyte including (i) an ion compound selected from the group consisting of lithium ions and sodium ions and (ii) a solvent, wherein the hybrid film is impregnated with the liquid electrolyte.

Claims (10)

1. A hybrid solid electrolyte comprising:

a hybrid film including (i) 60 to 100 parts by weight of an ion conductive ceramic and (ii) 1 to 40 parts by weight of a polymer; and

a liquid electrolyte including (i) an ion compound selected from the group consisting of lithium ions and sodium ions and (ii) a non-aqueous organic solvent,

wherein the hybrid solid electrolyte includes (i) 60 to 100 parts by weight of the hybrid film and (ii) 1 to 40 parts by weight of the liquid electrolyte,

wherein the liquid electrolyte is impregnated in the hybrid film in a manner in which the liquid electrolyte physically contacts the ion conductive ceramic and the polymer.

2. The hybrid solid electrolyte of claim 1 ,

wherein the hybrid solid electrolyte has a thickness of 30 μm or less.

3. The hybrid solid electrolyte of claim 1 ,

wherein the hybrid solid electrolyte has a thermal stability at 400° C. or more.

4. A secondary battery comprising the hybrid solid electrolyte according to claim 1 .
