Abstract: An electrode insulating coating composition according to the present disclosure includes boehmite particles, a dispersant, a binder, and a non-aqueous solvent, wherein the dispersant includes a phenolic compound containing two or more aromatic rings, and is included in an amount of 1.2 to 8.8 parts by weight with respect to 100 parts by weight of the boehmite particles.

Abstract: The present technology relates to a method of manufacturing an electrode for a secondary battery, and since an electrode is manufactured using an insulating composition including an aqueous binder substituted with a non-aqueous solvent, the wet adhesion of an insulating layer can be increased, and the gelation between an electrode slurry and the insulating composition, which is caused by using different types of binders, can also be prevented.

Abstract: The present technology relates to an insulating composition having excellent wet adhesion and a preparation method thereof, and since an insulating coating layer has excellent wet adhesion in a liquid electrolyte, there is an advantage in that migration of lithium ions in an overlay region of an electrode can be blocked to suppress capacity expression and the like.

Abstract: The present technology relates to a positive electrode for a lithium secondary battery, which includes an insulating layer having excellent wet adhesion, and a lithium secondary battery including the same, and they have an advantage in that migration of lithium ions in an overlay region of the electrode can be blocked to suppress capacity expression and the like due to the insulating layer having excellent wet adhesion in a liquid electrolyte.

Abstract: A water-repellent coating composition, and particularly, a water-repellent coating composition having improved adhesion and durability by including a phosphoric acid or a phosphoric acid-based compound, is provided.

Abstract: Provided are a reuse method of electrode scrap and a method of fabricating a recycled electrode using the same. The reuse method of electrode scrap of the present disclosure includes (a) dry milling electrode scrap remaining after punching an electrode sheet including an active material layer on a current collector to obtain milled products; and (b) screening active material layer flakes from current collector fragments in the milled products by sieving the milled products, and collecting the screened active material layer flakes to obtain reusable particles.

Abstract: The present technology relates to a manufacturing method for an electrode binder, comprising a step of dissolving pelletized polyvinylidene fluoride (PVDF) in a solvent; and an electrode assembly comprising the electrode binder. The present invention may provide an electrode assembly which has a low content of impurities in a binder solution, is capable of increasing dispersibility of an electrode active material, and exhibits excellent binding force.
