A separator including a gas generating agent and a method of manufacturing the same. More particularly, the separator has a porous coating layer including an inorganic material on at least one surface of a porous substrate, wherein the porous coating layer includes a gas generating agent.

Separator including gas generating agent and method of manufacturing the same

A coated separator for a secondary battery including a separator substrate including a porous polymer resin; and a coating layer present on at least one surface of the separator substrate. The coating layer includes an inorganic material and a coupling agent, the inorganic material comprises a hydroxide of a metal, or a hydroxide of a metal oxide, and the coupling agent is a titanium-based or a silane-based coupling agent.

Coated separator for secondary battery and method of manufacturing the same

A flame retardant separator for secondary batteries, and more particularly, a flame retardant separator for secondary batteries comprising or coated with a metal hydroxide having a low Gibbs free energy among polymorphs of a metal hydroxide used as an inorganic flame retardant.

Flame retardant separator for secondary battery

A slurry composition for coating a secondary battery separator, a separator prepared using the same, and a secondary battery including the separator, wherein the slurry composition includes a phenolic compound including two or more aromatic rings, inorganic particles, a binder, and a solvent.

Slurry composition for coating secondary battery separator and secondary battery separator prepared using same

A separator for secondary batteries that allows the amount of a dispersing resin that is used and the amount of a dispersant that is used to be reduced in order to prevent an increase in resistance after the separator is coated, which occurs in the case in which a large amount of the dispersing resin is used in order to disperse inorganic matter, and an electrochemical device having the same applied thereto. The amount of a dispersing resin is reduced, whereby it is possible to prevent an increase in resistance after a porous separator is coated, a dispersing resin having a specific weight average molecular weight is mixed, whereby physical properties and dispersivity are improved, and the use of an expensive dispersant is excluded, whereby processing costs are reduced.
