PLATE GRID AND MANUFACTURING METHOD THEREFOR, POLAR PLATE, AND LEAD-ACID STORAGE BATTERY
The present invention relates to the field of storage batteries, and disclosed thereby are a plate grid and a manufacturing method therefor, a polar plate, and a lead-acid storage battery; the plate grid comprises a tab, a frame body, and a plurality of conductive ribs that are intersectingly arranged inside of the frame body so as to form a grid structure; the frame body is higher than the grid structure in the thickness direction of the grid structure so that lead paste may fill the interior of the frame body by using the grid structure as a support; the frame body comprises a top beam that is made of a lead alloy material and that is disposed along a side edge of the grid structure, as well as side frames that are connected to two ends of the top beam and that are made by using a plastic material, the side frames and the top frame jointly forming the frame body surrounding the grid structure; and the tab is connected to the top frame. With regard to the plate grid and manufacturing method therefor, polar plate, and lead-acid storage battery provided by the present invention, the plate grid has relatively high strength and strong creep resistance, and does easily deform; moreover, the active substance of lead paste that is filled at the interior of the frame body does not easily fall off or become contaminated, while the weight and volume are relatively small, which is beneficial in reducing costs and improving the usage performance of a product.
A battery box (1); the battery box (1) is electrically connected to a power socket (6), an accumulator inserting slot (1a) is formed in the battery box (1), and a plurality of conductive members (5, 7) are provided on the inner wall thereof. When an accumulator (2) is fitted in the inserting slot, battery terminals (3) of the accumulator (2) matches and abuts conductive terminals (8) of the conductive members at corresponding positions to form an electric connection between the accumulator (2) and the power socket (6), enabling the accumulator (2) to be charged or discharged via the power socket (6). When a plurality of accumulators (2) are mounted in the accumulator inserting slot (1a), the plurality of conductive members except a socket conductive member (5) may also comprise battery conductive members (7), the conductive terminals at two ends thereof being electrically connected on the corresponding battery terminals of the two adjacent accumulators (2) to connect the accumulators (2) in series. Also disclosed is a fast-mounting accumulator system comprising the battery box (1), the system comprising the battery box (1), the accumulator (2) and the power socket (6). Also disclosed is an electric vehicle comprising the fast-mounting accumulator system. The system enables the accumulator to be conveniently and efficiently mounted, thus effectively addressing the problems such as battery leakage and electric energy reduction caused by welding.
Provided is a method for recycling a lead oxide-containing waste material, comprising: (1) contacting the lead oxide-containing waste material with a desulphurizer under desulphurization reaction conditions, and performing a solid-liquid separation on the mixture after contacting to obtain a filtrate and a filtration residue; (2) performing a conversion reaction on the above-mentioned filtration residue at a temperature of 350-750°C so as to convert the lead-containing components in the filtration residue into lead oxide; (3) contacting the product obtained from step (2) with an alkaline solution so as to dissolve the PbO therein, and then performing a solid-liquid separation to obtain a PbO-alkaline solution; and (4) crystallizing the PbO-alkaline solution from step (3) to obtain PbO crystals and an alkaline filtrate. The method can reduce the energy consumption.
Provided is a method for directly recovering lead oxide used for a lead-acid battery cathode from waste lead paste. The method comprises: (1) contacting waste lead paste with a barium-containing desulphurizer under desulphurization reaction conditions, and performing a solid-liquid separation on the mixture after contacting to obtain a filtrate and a filtration residue; and (2) performing a conversion reaction on the above-mentioned filtration residue at a temperature of 350-750°C so as to convert the lead-containing components in the filtration residue into lead oxide. In the method, the direct recovery of a lead oxide raw material applicable to a lead-acid battery cathode from waste lead paste is achieved by quantitatively replenishing a barium sulphate additive in the process of desulphuration, thereby substantially decreasing the recovery cost and energy consumption, and improving the comprehensive utilization of waste lead paste.
