Patent number: 9577266Abstract: A method for producing a negative grid for a battery which includes providing a strip of battery grid material and performing a punching operation on the battery grid material to remove material and form a grid. The punching operation produces a negative battery grid having a plurality of grid wires bounded by a frame. The battery grid includes a top frame member. A first side frame member is coupled to the top frame member at a first end thereof. A second side frame member is coupled to the top frame member at a second end thereof. A bottom frame member is spaced apart from the top frame member and coupled to the first side frame member and the second side frame member. The negative grid does not include exposed wire ends that may puncture a polymeric separator when the negative grid is provided within the separator.Type: GrantFiled: February 29, 2008Date of Patent: February 21, 2017Assignee: Johnson Controls Technology CompanyInventors: Jeffrey L. Troxel, Charles J. Schaeffer, Glenn W. Andersen, Michael E. Lacroix, Wen-Hong Kao

Patent number: 8252464Abstract: A method of forming battery grids or plates that includes the step of mechanically reshaping or refinishing battery grid wires to improve adhesion between the battery paste and the grid wires. The method is particularly useful in improving the past adhesion to battery grids formed by a continuous batter grid making process (such as strip expansion, strip stamping, continuous casting) that produces grid wires and nodes with smooth surfaces and rectangular cross-section. In a preferred version of the method, the grid wires of battery grids produced by a stamping process are deformed such that the grid wires have a cross-section other than the rectangular cross-section produced by the stamping process. The method increases the cycle life of a battery.Type: GrantFiled: November 7, 2011Date of Patent: August 28, 2012Assignee: Johnson Controls Technology CompanyInventors: Charles J.
