NOVELTY - Manufacture of an electrode involves continuously applying a battery electrode slurry composition comprising electrochemically active material comprising a positive battery electrode active material or a negative battery electrode active material, an organic medium comprising trialkyl phosphate, and a binder comprising a fluoropolymer comprising the residue of vinylidene fluoride, and one or more (meth) acrylic polymers comprising constitutional units comprising the residue of (i) 40-80 wt.% alkyl ester of (meth) acrylic acid containing 1-3 carbon atoms in alkyl group, (ii) 18-48 wt.% alkyl ester of (meth) acrylic acid containing 4-18 carbon atoms in alkyl group, (iii) 0.1-10 wt.% hydroxyalkyl ester, (iv) 0-10 wt.% α , β -ethylenically unsaturated carboxylic acid and (v) 0-20 wt.% ethylenically unsaturated monomer comprising heterocyclic group with respect to the total monomer weight that comprise one or more (meth) acrylic polymers and optionally electrically conductive agent. USE - Manufacture of electrode for electrical storage device e.g. cell, battery pack, secondary battery, capacitor and supercapacitor (all claimed). ADVANTAGE - The method provides a battery having excellent battery performance at low temperature. DETAILED DESCRIPTION - Manufacture of an electrode using a continuous coating line for applying an electrode coating layer on a substrate surface of a substrate, the continuous coating line comprising a coating apparatus comprising a coating head and a coating fluid supply system, and at least one oven comprising a heating element, and a substrate carrier for carrying the substrate, involves continuously carrying the substrate through the continuous coating line using the substrate carrier, continuously applying a battery electrode slurry composition from the coating head to the substrate surface to form a wet coated substrate, continuously feeding the battery electrode slurry composition into the coating head by the coating fluid supply system and heating the wet coated substrate in the oven to form a dried coating on the substrate. The battery electrode slurry composition comprises an electrochemically active material comprising a positive battery electrode active material or a negative battery electrode active material, an organic medium comprising trialkyl phosphate and a binder comprising (a) a fluoropolymer comprising the residue of vinylidene fluoride and (b) one or more (meth) acrylic polymers comprising constitutional units comprising the residue of (i) 40-80 wt.% alkyl ester of (meth) acrylic acid containing 1-3 carbon atoms in the alkyl group, (ii) 18-48 wt.% alkyl ester of (meth) acrylic acid containing 4-18 carbon atoms in the alkyl group, (iii) 0.1-10 wt.% hydroxyalkyl ester, (iv) 0-10 wt.% α , β -ethylenically unsaturated carboxylic acid and (v) 0-20 wt.% ethylenically unsaturated monomer comprising a heterocyclic group with respect to the total monomer weight that comprise one or more (meth) acrylic polymers and optionally an electrically conductive agent. INDEPENDENT CLAIMS are included for the following: electrode; and electrical storage device, which comprises the electrode, a counter electrode and an electrolyte.
