Abstract

The invention discloses a cascade utilization recycle process of an energy storage lithium ion battery. The cascade utilization recycle process comprises the following steps of building a closed disassembly operation space; stacking the lithium ion battery needed to be disassembled in a battery loading bin, sealing the disassembly operation space, and vacuumizing the disassembly operation space; breaking and disassembling the lithium ion battery by extrusion effects of two extrusion rollers so that an electrolyte in the lithium ion battery flows out of a fixed shell of the lithium ion battery; and stacking the lithium ion battery broken by extrusion at the bottom of a battery disassembly bin, enabling to lead out a liquid recycle substance by connecting a liquid discharge pipe at the bottom of the battery disassembly bin, and finally, opening the battery disassembly bin to take out a solid recycle substance in the battery disassembly bin after the disassembly operation is completed. With the cascade utilization recycle process of the energy storage lithium ion battery, provided by the invention, gradual feeding and disassembly operation of the lithium ion battery can be automatically completed.

Description

technical field [0001] The invention relates to the technical field of recycling lithium-ion batteries, in particular to a recycling process for step-by-step energy storage lithium-ion batteries. Background technique [0002] As a green battery, lithium-ion battery has the advantages of high energy density, high working voltage, high safety performance and long service life, so it shows excellent prospects in new energy storage such as portable electronic devices and electric vehicles. According to national standards, if the capacity of the power battery drops to 80% of the rated capacity, it means the end of its life. If the battery is eliminated directly, it will cause a serious waste of resources; therefore, when the power battery is not suitable for continued use on existing vehicles, It can be recycled and reused in the battery energy storage system for cascade utilization, and can be used for peak shaving and valley filling in the power system, thereby improving the st...
