The present invention provides an electrical storage device binder composition that can produce an electrode that achieves improved charge-discharge characteristics. The composition includes a polymer (A) and a liquid medium (B), and further includes particles having a particle size of 10 to 50 micrometers in a number of 1,000 to 100,000 per mL.

Method for producing electrical storage device electrode with binder composition

A binder composition for power storage devices comprising a polymer which contains at least 3 to 40 mass % of a first recurring unit derived from an unsaturated carboxylic acid ester having an alicyclic hydrocarbon group and 1 to 40 mass % of a second recurring unit derived from an &#x3b1;, &#x3b2;-unsaturated nitrile compound based on 100 mass % of the total of all recurring units.

Binder composition for power storage devices

A composition for forming a protective film that is placed between a positive electrode and a negative electrode of an electrical storage device, includes polymer particles (A1), polymer particles (A2), and a liquid medium, the polymer particles (A1) including a repeating unit derived from a compound that includes two or more polymerizable unsaturated groups in an amount of less than 15 parts by mass based on 100 parts by mass of the polymer particles (A1), and the polymer particles (A2) including a repeating unit derived from a compound that includes two or more polymerizable unsaturated groups in an amount of 20 to 100 parts by mass based on 100 parts by mass of the polymer particles (A2).

Composition for producing protective film, protective film, and electrical storage device

An electrical storage device includes a cathode, an anode, a protective film that is provided between the cathode and the anode, and an electrolyte solution, the protective film including a polymer that includes a repeating unit derived from a fluorine-containing monomer, and a repeating unit derived from an unsaturated carboxylic acid.

Protective film and composition for preparing the same, slurry, and electrical storage device

An electrode binder composition that is used to produce an electrode used for an electrical storage device, includes (A) a polymer, (B) a carboxylic acid or a salt thereof, and (C) a liquid medium, and has a concentration of the carboxylic acid or a salt thereof (B) of 20 to 1000 ppm.
