Recycling device of waste lithium battery electrolyte lithium hexafluorophosphate and application method of recycling device

Abstract

The invention discloses a recycling device of a waste lithium battery electrolyte lithium hexafluorophosphate, and relates to the technical field of a lithium battery. The recycling device comprises aheating box, wherein a heat preservation layer is fixedly connected to the heating box, a processing box communicates with the top of the heating box, a case is fixedly connected with the bottom of the heating box, an air blower and a heater are sequentially and fixedly connected to the case from left to right, and an air outlet of the air blower communicates with an air blowing pipe. According to the recycling device of the waste lithium battery electrolyte lithium hexafluorophosphate and an application method of the recycling device, a medicine can be discharged to a right side of a processing plate by matching of a water pump and a water outlet pipe, the medicine mixed with waste gas can reflow to a medicine at a left side of a first partition plate by slope of the processing plate, the waste gas which is not mixed can be introduced to the medicine again for thorough dissolving by arranging a reflow pipe, and the waste gas can be thoroughly removed; and by processing for two times,the problem that the waste gas is not thoroughly dissolved for one time is prevented, and the air quality is ensured.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a recycling device and a use method for lithium hexafluorophosphate electrolyte solution of waste lithium batteries. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, are superior to lithium-ion batteries in terms of safety, specific capacity, self-discharge rate and performance-price ratio. Due to its own high technical requirements, only companies in a few countries are currently producing such lithium metal batteries. Lithium metal batteries are generally batteries that use ma...
