Abstract

The invention discloses a waste lithium ion battery discharge and hydrogen production integrated system and method. The integrated system comprises a power supply, an electrolytic tank, a controller, a battery appearance detection device and a battery charge and discharge performance testing device, wherein the power supply is obtained by assembling by a plurality of waste lithium ion battery units; the power supply is connected with the electrolytic tank to provide electric energy required by electrolytic reaction for the electrolytic tank; the residual electric quantity of decommissioned batteries is effectively utilized by a process of producing hydrogen by electrolyzing water; and the decommissioned batteries subjected to full discharge can directly enter a recycling disassembly step, so that the residual electric energy is utilized, and a discharge step is omitted.

Description

technical field [0001] The invention belongs to the field of waste battery recycling, and relates to a waste lithium ion battery discharge and hydrogen production integrated system and method. Background technique [0002] With the increase in battery usage, the number of retired batteries has risen sharply. Since the anode and cathode materials, electrolytes and other substances of decommissioned batteries will cause environmental pollution to a certain extent, and at the same time, decommissioned batteries still contain certain valuable metals, waste batteries must be recycled. Since used batteries usually contain a certain amount of residual power, they first need to be discharged in the traditional recycling process. The current discharge process is brine discharge, which not only produces a large amount of high-salt discharge wastewater, but also wastes the remaining energy in the battery. Certain means should be adopted to replace the brine discharge process and real...
