Abstract

The invention discloses a lead-acid storage battery plate grid of a staircase structure. The plate grid comprises a plate grid body, the plate grid body is composed of an upper frame, a lower frame and a side frame, and transverse ribs and vertical ribs are arranged in the plate grid body. The plate grid is characterized in that trapezoidal gaps are formed in the side frame, the length of the trapezoidal gaps is smaller than the spacing distance between every two adjacent transverse ribs of the plate grid, and the depth of the trapezoidal gaps is smaller than one half of the thickness of the plate grid; each trapezoidal gap is distributed between every two adjacent transverse ribs of the plate grid body, and the trapezoidal gaps are evenly distributed in an array mode. By improving the plate grid frame and designing the plate grid frame to be of the staircase structure, the lead-acid storage battery plate grid has the advantages that the original thickness of the plate grid keeps invariable, therefore, the void volume of plate grid filling lead paste is guaranteed, and the paste stacking phenomenon is avoided; the specific surface area of the lead paste is increased, and the high-current performance of a lead-acid storage battery is improved; the using amount of rare earth-silver alloy is decreased, and therefore the material cost is reduced.

Description

technical field [0001] The invention relates to the technical field of battery grids, in particular to a lead-acid battery ladder structure grid, pole plates and a manufacturing process for the pole plates. Background technique [0002] China's electric vehicle was born in 1985 and began to develop rapidly in 2003. After five years of speed-up, the industry scale and production and sales have maintained an annual growth of more than 50%. Especially in the two years of 2005 and 2006, the development of the electric vehicle industry has entered Blowout period. [0003] Lead-acid batteries are stacked with positive and negative plates interleaved in the battery box, and the positive and negative plates are separated by insulating separators. When the electrolyte is filled into the battery box, the electrolyte reacts chemically with the lead paste on the positive and negative plates. When the battery is charged, the lead paste on the positive plate is converted into lead dioxid...
