A HYBRID POLYMER ELECTROLYTE FABRICATED BY A SPRAY METHOD, A LITHIUM SECONDARY BATTERY COMPRISING THE HYBRID POLYMER ELECTROLYTE AND THEIR FABRICATION METHODS

摘要

The present invention provides a novel hybrid polymer electrolyte, a lithium secondary battery comprising the hybrid polymer electrolyte and their fabrication methods. More particularly, the present invention provides the hybrid polymer electrolyte comprising a porous polymer matrix with particles, fibers or mixture thereof having diameters of 1 - 3000 nm, polymers and lithium salt-dissolved organic electrolyte solutions incorporated into the porous polymer matrix. The hybrid polymer electrolyte has advantages of better adhesion with electrodes, good mechanical strength, better performance at low- and high-temperatures, better compatability with organic electrolytes of a lithium secondary battery and it can be applied to the manufacture of lithium secondary batteries.
