摘要： Battery separators are provided that include nanoalumina crystals and/or fibers, and a fiber blend including organic fibers. In one or more embodiments, the organic fibers can have a negative zeta potential in water prior to formation of the separator such that electrostatic adsorption of the nano-alumina crystals and/or fibers can occur. The battery separators are free of coatings and exhibit low shrinkage after one hour at temperatures up to 230°C, minimal pore sizes, a BET surface area greater than 10 m2/g. Also disclosed is a wet laid process for forming the battery separators.

摘要： A method for manufacturing a storage device (100) disclosed herein includes a winding step (S3) of winding a positive electrode (22) and a negative electrode (24) with a separator (26) interposed therebetween to manufacture a wound body (20A), and a pressing step (S4) of pressing the wound body (20A) to form the wound body (20A) into a flat wound electrode body (20a). In the winding step (S3), a separator (26) including an adhesion layer (6) arranged in a shape of a plurality of dots is used. Each of the dots of the adhesion layer (6) includes an adhesion layer non-formed region (E) in a central portion thereof when viewed from top. In the pressing step (S4), an area of the adhesion layer non-formed region (E) when viewed from top is reduced to 1/2 or less.

摘要： There is provided a power storage device separator binder aqueous solution, where the power storage device separator binder aqueous solution contains a water soluble polymer (1) or contains a water soluble polymer (2) and a hydrazide. The water soluble polymer (1) contains 20% by mole to 80% by mole of an N,N-dialkyl (meth)acrylamide unit and 10% by mole to 80% by mole of a (meth)acrylamide unit. The water soluble polymer (2) contains 0.2% by mole to 10% by mole of a keto group-containing ethylenically unsaturated monomer unit and 65% by mole to 99.7% by mole of a (meth)acrylamide group-containing compound unit. The hydrazide has two or more hydrazide groups.
