Embodiment 1
[0023] This embodiment adopts 6-DZM-20 lead-acid batteries for electric mopeds to recycle and reuse processing technology: first, for scrapped lead-acid batteries (batteries with a capacity lower than the standard or thermal runaway after charging) in the reserved 1 / 2 pole In the case of group busbars, saw the slot cover, use a multimeter with a DC voltage range of 0-20V to measure the open circuit voltage of each monomer, remove the monomers with a voltage difference lower than 1.0V, and remove the monomers with a voltage difference lower than 1.0V. direct smelting and recycling. Select waste lead-acid batteries with normal voltage as recyclable batteries.
[0024] Take out the pole group of the waste lead-acid battery with normal voltage, discard the separator between the positive and negative plates, and place the positive and negative pole groups respectively in plastic containers resistant to corrosion and high temperature of 80-100°C. Dry at 70°C until the water content...

Abstract
The invention discloses a processing technique for the recycling and reusing of waste lead acid accumulators, which realizes reusing by proper treatment to positive plates and negative plates in the waste lead acid accumulators. The positive plates are dried first after the waste lead acid accumulators are detached to separate active materials from grids; active materials are separated from a plate grid, and after grinding and sieving, the active materials which is taken as additives can be applied for the manufacturing of the anodes of the new batteries. The negative plates, after charging and reduction in dilute sulfuric acid, receive oxidation-resistant treatment and drying, and can be independently added or blended into the cathode groups of the new batteries so as to realize twice use or repeated use many times. The processing technique for the recycling and reusing of the waste lead acid accumulators can carry out the recycling and processing of the waste lead acid accumulators, and realize reusing in the newly assembled lead acid accumulators which can be delivered out of the factory in the form of dry charged battery attached with acidizing fluid or in the form of wet charged battery according to the general techniques, and put into normal operation. With good performance, the reused lead acid accumulators are provided with same functions with newly-manufactured batteries; meanwhile, the production cost is reduced.
Description
technical field [0001] The invention relates to a process for recycling waste lead-acid batteries. Background technique [0002] With the development of the national economy, the advancement of science and technology and the improvement of people's lives, the application of lead-acid batteries is becoming more and more extensive, and the environmental pollution caused by waste lead-acid batteries is getting more and more attention. Heavy weight, short life and high cost of use, so recycling has become the best way to deal with waste lead-acid batteries. Contents of the invention [0003] The purpose of the present invention is to provide a process for recycling and reusing waste lead-acid batteries. In the present invention, waste lead-acid batteries can be used in newly assembled lead-acid batteries after being recycled and processed, and can be used in dry-charged batteries according to the normal process. Batteries are shipped with acid or wet-charge batteries and put ...
