    摘要： 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.
