The method comprises the steps of at least combining an electrode active material, one or more conductive diluents, a binder and a solvent to form an electrode active mixture having a first solvent to powder weight ratio, reducing a solvent to powder weight ratio to form a paste, feeding the paste into a plastic tube; and calendering the plastic tube. A dry cathode mixture is provided. The dry cathode mixture includes a cathode active material, a conductive diluent and a polymeric binder. A solvent is mixed with the dry mixture to form a slurry. Solvent is removed from the slurry to form a doughy composition. The doughy composition is calender sheeted to form a sheet. The sheet is baked at a temperature of 30° C. to 120° C. for 15 minutes to 6 hours to form a dry sheet. The dry sheet is cut into coupons. The coupons are pressed to form a pressed coupon.Type: GrantFiled: September 18, 2017Date of Patent: November 24, 2020Assignee: Pacesetter, Inc.Inventors: Xiaofei Jiang, Russell Bruch, Joseph Beauvais

Patent number: 10468706Abstract: A REDOX flow battery or fuel battery includes a reactant storing and collecting unit for preventing leakage of a reactant. The battery includes two end plates and a stack that is disposed between the end plates and includes one or more unit cells. The reactant storing and collecting unit for preventing leakage of a reactant is disposed inside or outside the stack. According to the present invention, sealing reliability of the REDOX battery or fuel battery is dramatically improved. In addition, although a reactant or a product leaks from the stack, the reactant or the product may not leak to an outside of the battery but is collected before leaking to the outside. Therefore, the battery according to the present invention has an advantage of easy maintenance.Type: GrantFiled: December 31, 2014Date of Patent: November 5, 2019Assignee: STANDARD ENERGY CO., LTD.Inventors: Bu Gi Kim, Da Young Kim
