Embodiment Construction

[0045] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0046] refer to figure 1 , a recycling method for aluminum-air batteries of the present invention, comprising the following steps:

[0047] Recycling aluminum-air batteries: recycle the discarded aluminum-air batteries after use;

[0048] Recycling and treatment of electrolyte: extract the electrolyte in the recovered aluminum-air battery into the sedimentation tank, add a precipitant, static precipitation, collect the precipitate and supernatant; convert the pretreated electrolyte precipitate into pure Aluminum oxide is recovered; the supernatant produced after electrolyte pretreatment removes free aluminum ions, and aluminum ions are precipitated to obtain recyclable aluminum-air battery electrolyte;

[0049] Dismantling and recycling of the battery body: disassemble the battery body that has drained the elect...

Abstract

The invention discloses an aluminum-air battery recycling method. The method includes the following steps that used waste aluminum-air batteries are recycled; electrolyte in the recycled aluminum-air batteries is pumped into a settling pond, precipitator is added, the mixture is still standing and precipitated, and precipitate and supernate are collected; the pretreated electrolyte precipitate is purified and converted to obtain pure aluminum oxide for recycling; free aluminum ions of the supernate generated after pretreatment of the electrolyte are removed, and after the aluminum ions are subjected to sedimentation treatment, aluminum-air battery electrolyte capable of being recycled is obtained; battery bodies without the electrolyte are detached, plastic shells and metal parts are obtained, plastic is recycled according to the national standard GB/T 30102-2013, and metal is recycled according to corresponding metal national standards to be reused; obtained oxygen catalyst electrodes are processed to obtain a catalyst containing nickel oxide and manganese oxide, and then the obtained catalyst containing nickel oxide and manganese oxide is prepared into new oxygen catalyst electrodes of aluminum-air batteries.

Description

technical field [0001] The invention relates to the technical field of recycling aluminum-air batteries, in particular to a recycling method for aluminum-air batteries. Background technique [0002] With the advancement of science and technology and the rapid development of the economy, people's daily life is filled with all kinds of primary and secondary batteries. The use of batteries brings great convenience to our life, but the waste batteries released such as The pollution of precious metals such as , mercury, cobalt and organic electrolytes to soil and water sources is becoming increasingly prominent. At present, the recycling technology of various types of batteries is relatively lacking, there is no mature commercial company to deal with, and the recycling channels are not smooth. Therefore, the development of a new type of energy with high energy density, environmental friendliness, easy recycling and sustainable development is an important topic of energy developm...
