COMPOSITION FOR GEL POLYMER ELECTROLYTE AND LITHIUM SECONDARY BATTERY INCLUDING THE SAME
20180171063 · 2018-06-21 · ·

The present invention relates to a composition for a gel polymer electrolyte and a lithium secondary battery including the same, and more specifically, an objective of the present invention is to provide a secondary battery in which, since an isocyanate-containing monomer is introduced to a composition for a gel polymer electrolyte to induce a urethane reaction with LiOH on a surface of a lithium transition metal oxide to form a coating layer including a urethane bond-containing oligomer on the surface of the lithium transition metal oxide, and thereby side reactions caused by HF in the battery are minimized, capacity characteristics are improved, and adhesion between a positive electrode and a separator is enhanced to minimize the swelling phenomenon of the battery.
