Problems solved by technology

[0002] When the current lead-acid battery industry recycles waste lead paste, it mainly adopts pyrometallurgy, and a small proportion of waste lead paste is recycled and reused through electrolysis. Compared with the recycling and recycling of other components, such as grids, waste acid, and battery shells, the recycling process is technically difficult, polluting, high energy consumption, and high cost

Embodiment 1

[0035] This embodiment relates to the recycling and utilization of lead-acid battery waste lead paste, including separating the lead-acid battery waste lead paste from the damaged battery current collector material, and then, the waste lead paste to be obtained is used as The regenerated lead-acid battery active material is directly coated on the new lead-acid battery grid to manufacture the flat grid electrode of the lead-acid battery, and use the electrode to manufacture the lead-acid battery or battery pack, and then pass this embodiment During the process of using or being used, the lead-acid storage battery or battery pack manufactured by the method carries out or is carried out the positive and negative polarity reversal of the lead-acid storage battery or / and lead-acid storage battery pack and subsequent charging or charging and discharging operations, The total accumulative times of the lead-acid storage battery or the battery pack described in this embodiment performin...

Embodiment 2

[0052] This embodiment relates to the recovery and utilization of waste active materials of lead-acid batteries, including separating the waste active materials from the current collector material of the battery, and then drying the obtained waste active materials, stirring them evenly, and adjusting the apparent density After one or more of these operations, dry powdery particles are formed, and then the formed dry powdery particles are directly applied to the manufacture of tubular lead-acid battery electrodes as regenerated active substances, thereby manufacturing tubular or fully tubular lead-acid storage battery or battery pack, then the tubular or all-tubular lead-acid storage battery or battery pack manufactured by the method of this embodiment is used or used to carry out or be carried out as lead-acid storage battery or / and lead-acid storage battery Polarity reversal of positive and negative poles and subsequent charging or charging and discharging operations. The lead...

Embodiment 3

[0092] This embodiment relates to the recovery and utilization of lead-acid battery waste lead compound paste. The waste lead compound paste in this embodiment mainly includes lead dioxide, lead sulfate, lead monoxide, and metallic lead. The method for reclaiming and reusing the waste lead compound paste of lead-acid batteries in this embodiment includes: heating the waste lead compound paste in this embodiment, adding water, stirring evenly, and adjusting the apparent density to form a Wet powder or paste with a certain humidity, and then the formed wet powder or paste with a certain humidity is directly applied to the electrode of a lead-acid battery as a regenerated active material, thereby manufacturing a lead-acid battery or battery pack, Then, during use or being used, the lead-acid storage battery or / and the lead-acid storage battery positive and negative polarity reversal of the lead-acid storage battery or / and lead-acid storage battery and subsequent For charging or c...

Abstract

The invention discloses a lead-acid storage battery scrap lead plaster recycling method. The lead-acid storage battery scrap lead plaster recycling method is characterized in that scrap lead plaster breaks away from a battery current collector material and then serves as a regenerated lead-acid storage battery active substance which is directly applied to manufacturing of lead-acid storage batteries or battery packs without treatment or only through simpler mechanical, chemical and electrochemical treatment, polarity reversal of positive and negative poles of lead-acid storage batteries and / orlead-acid storage battery packs and follow-up charging or charging-discharging operations are performed in the using or used process of the manufactured lead-acid storage batteries or battery packs,and the total accumulated operating or operated times of the lead-acid storage batteries or battery packs is greater than or equal to 2. The lead-acid storage battery scrap lead plaster recycling method is conductive to great reduction of process complexity, pollution, energy consumption, cost and device requirements of scrap lead plaster recycling.

Description

technical field [0001] The invention relates to a recycling method for a lead-acid storage battery, in particular to a recycling method for waste lead paste of a lead-acid storage battery. Background technique [0002] When the current lead-acid battery industry recycles waste lead paste, it mainly adopts pyrometallurgy, and a small proportion of waste lead paste is recycled and reused through electrolysis. Compared with the recycling and recycling of other components, such as grids, waste acid, and battery shells, the recycling and recycling process is technically difficult, polluting, high in energy consumption, and high in cost. Reducing the process complexity, pollution, energy consumption, and cost level of waste lead paste recycling and recycling has good social and economic benefits, and is conducive to the better development of human beings. Contents of the invention [0003] The problem to be solved by the present invention is to provide a method for recycling wa...
