Recycling and dismantling method of lithium iron phosphate power battery

Abstract

The invention discloses a recycling and dismantling method of a lithium iron phosphate power battery. The method comprises a recycling and dismantling device, wherein the recycling and dismantling device comprises a battery feeding bin, a battery dismantling bin and a helium gas storage tank; the battery feeding bin is provided with a feeding hole and a charging hole; the battery dismantling bin is provided with a dismantled material outlet; a positioning and pressing roller, a cutting and pressing roller and a pressing and dismantling region are arranged between the dismantled material outlet and the charging hole; and the method comprises the following steps of: vacuumizing the battery feeding bin and the battery dismantling bin; making the helium gas storage tank communicate with the battery dismantling bin, adding the lithium iron phosphate power battery to the battery feeding bin and vacuumizing the battery feeding bin; entering the lithium iron phosphate power battery into the battery dismantling bin through the charging hole and separating an electrolyte from a solid assembly; and discharging the dismantled electrolyte and the solid assembly out of the battery dismantling bin. The recycling and dismantling operations of the lithium iron phosphate power battery can be automatically finished.

Description

technical field [0001] The invention relates to the technical field of new energy power lithium batteries, in particular to a method for recycling and dismantling lithium iron phosphate power batteries. Background technique [0002] New energy refers to various energy forms other than traditional energy that have just begun to be developed and utilized or are being actively researched and yet to be promoted. New energy can effectively deal with oil crises and environmental pollution, such as solar energy, geothermal energy, and wind energy. , ocean energy, biomass energy and nuclear fusion energy, etc.; the storage, transfer and utilization of new energy is a key link in the promotion of new energy, and it is also a technical problem of key public relations. The storage of new energy mainly uses certain technologies to convert new energy into chemical energy, Potential energy, kinetic energy, electromagnetic energy and other forms make the converted energy have the character...

Problems solved by technology

In the prior art, professional lithium-ion traction battery recycling equipment has not been disclosed. Due to the wide variety of models and varieties of lithium-ion traction batteries in China, most of them manually disassemble lithium-ion traction batteries. The above dismantling methods are not only for materials The recycling rate is low and the work efficiency is low; in addition, the operator may come into contact with the battery waste liquid during the manual dismantling of the lithium-ion power battery, which will endanger the health of the workers; thirdly, the waste lithium-ion power battery still has High chemical activity, active metals may cause explosion after contact with air or oxidizing gas, which will endanger the personal safety of operators
