Lithium ion battery electrolyte recycling device and method

Abstract

The invention discloses a lithium ion battery electrolyte recycling device which comprises a conduit, a vacuuming device, a condensation recycling device, a heating device, a main controller and a temperature sensor, wherein the main controller is connected with the temperature sensor, the heating device and the vacuuming device respectively; the controller is used for controlling a lithium ion battery at a constant temperature state to recycle electrolyte through the heating device in the recycling process; the temperature sensor is arranged on the outer surface of the lithium ion battery; the heating device is adhered to the lithium ion battery; the vacuuming device is connected with the lithium ion battery and the condensation recycling device through the conduit respectively. By adopting the recycling device disclosed by the invention, the problems that lithium ion battery electrolyte is hard to recycle, security accidents can be easily caused in the recycling process, and the like, can be solved.

Description

technical field [0001] The invention relates to the field of recovery of lithium ion batteries, in particular to a recovery device and method for electrolyte solution of lithium ion batteries. Background technique [0002] At present, there is no method and device for recycling lithium-ion batteries with safety valves on the premise of ensuring safety, reducing the degree of battery cell damage, and reducing environmental pollution. The only electrolyte recovery method needs to realize the recovery after dismantling the lithium-ion battery, and its disadvantages are: 1. The dismantling of the lithium-ion battery and the recovery of the electrolyte consume a lot of manpower and material resources. 2. After the lithium-ion battery is dismantled, part of the electrolyte volatilizes into the dismantling environment, pollutes the dismantling equipment, and cannot be recycled. 3. The dismantling process is likely to cause a short circuit of the lithium-ion battery, which poses a ...

[0002] At present, there is no method and device for recycling lithium-ion batteries with safety valves on the premise of ensuring safety, reducing battery cell damage, and reducing environmental pollution.

The only electrolyte recovery method needs to realize the recovery after dismantling the lithium-ion battery. The disadvantages are: 1. The disassembly of the lithium-ion battery and the recovery of the electrolyte consume a lot of manpower and material resources

2. After the lithium-ion battery is dismantled, part of the electrolyte volatilizes into the dismantling environment, pollutes the dismantling equipment, and cannot be recycled

3. The dismantling process is likely to cause a short circuit of the lithium-ion battery, which poses a safety hazard and induces a safety accident
