POROUS HEAT-RESISTANT LAYER COMPOSITION, SEPARATION MEMBRANE COMPRISING POROUS HEAT-RESISTANT LAYER COMPOSITION, AND LITHIUM SECONDARY BATTERY USING SAME |
摘要 |
The present invention relates to a porous heat-resistant layer composition for a separation membrane for a battery, comprising: a crosslinkable binder selected from monomeric oligomers, polymers or mixtures thereof having at least one functional group; an inorganic particle surface-treated with a functional group capable of reacting with the crosslinkable binder; a polymerization initiator; and a solvent. Also, the present invention relates to a separation membrane and a lithium secondary battery comprising the same, the separation membrane comprising a porous substrate and a porous heat-resistant layer formed on one or both sides of the substrate, wherein the porous heat-resistant layer comprises a crosslinked structure binder and an inorganic particle, and the inorganic particle is surface-treated with a functional group and reacted with the crosslinked structure binder. |
