Provided is an organic and inorganic composite polymer electrolyte and an all-solid-state battery including the same, and provided is an organic and inorganic composite polymer electrolyte including a flame-retardant polymer and a flame-retardant inorganic salt with a shear modulus of 7 to 60 GPa, and an all-solid-state battery including the organic and inorganic composite polymer electrolyte.

Organic and inorganic composite polymer electrolyte and all solid state battery comprising the same

A polymer electrolyte for a lithium secondary battery that may include: a fluorine-based solvent; a lithium salt; and a flame retardant polymer containing phosphorus and fluorine, wherein the polymer electrolyte has a fluorine content of 35 to 60% by weight and a phosphorus content of 2.3 to 7.5% by weight. Lithium secondary batteries containing the polymer electrolyte exhibit improved flame retardancy and ionic conductivity as well as enhanced high-voltage stability.
