Description

Cylindrical lithium ion battery shell convenient to disassemble

Technical Field

The invention relates to the field of cylindrical battery components, in particular to a cylindrical lithium ion battery shell convenient to disassemble.

Background

The cylindrical battery is divided into different systems of lithium iron phosphate, lithium cobaltate, lithium manganate and cobalt manganese mixture and ternary materials, the shell is divided into a steel shell and a polymer, and the batteries with different material systems have different advantages. The cylinder mainly takes a steel shell cylindrical lithium iron phosphate battery as a main part, and the lithium iron battery has the advantages of high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, capability of discharging with large current, electrochemical stability, safety in use, wide working temperature range and environmental friendliness. The cylindrical battery is widely applied to electric tools, backup energy sources, toy models, notebook computers and new energy automobiles.

China is one of the biggest lithium ion battery production and consumption countries in the world, the increase of the lithium ion battery output inevitably brings the increase of the lithium ion battery scrap quantity, and the full and reasonable resource utilization of the waste lithium ion battery has important economic value for reducing the cost of the lithium ion battery. Not only can reduce the preparation cost and the environmental pollution, but also can relieve the situation that the lithium resource is increasingly reduced, and has important social and economic values.

The existing battery recovery technology mainly adopts pyrogenic calcination extraction or wet chemical extraction, but the battery is required to be disassembled or crushed and then further refined by both pyrogenic method and wet method. However, since the case of the cylindrical battery is difficult to be disassembled, the entire battery is generally crushed together without peeling the case and then crushing the battery. This just leads to shell and electric core to mix together, and the later stage must still separate the screening through modes such as magnetic separation, retrieves for the battery and refines difficulty and cost increase.

In the prior art, a special shell stripping machine is provided, but batteries have a plurality of models, and a plurality of waste batteries are deformed, so that the problems that a card machine and a battery core are damaged and stripped together and the like are often caused when the shell stripping machine is used in actual operation. The cylindrical shell which is not easy to detach is not arranged in the prior art, the cylindrical shell is integrally formed and is inconvenient to detach, so that the cylindrical battery shell which is easy to detach is urgently needed, and the whole shell can be easily peeled off in the later-stage recovery process.

Disclosure of Invention

The invention aims to provide a cylindrical lithium ion battery shell convenient to disassemble, which is mainly used for solving the problem that the shell of a cylindrical battery is inconvenient to disassemble due to integral forming.

The technical problem of the invention is mainly solved by the following technical scheme: including metal casing, the inboard of shell is equipped with the die-cut trace, the die-cut trace does not have the die-cut penetrating of shell casing, the outside of shell be equipped with the corresponding mar in die-cut trace position, the shell is in the one end of die-cut trace is equipped with tears the hand, the top of shell is packaged with the hood, the centre of hood is equipped with the male terminal post.

Preferably, two longitudinal die-cutting marks are arranged on the inner side of the outer shell, and a longitudinal tearing hand is arranged at the top end of each die-cutting mark of the outer shell.

Preferably, two transverse die cuts are formed in the inner side of the outer shell, and a transverse tearing hand is arranged at one end of each die cut on the outer shell.

Preferably, the inner side of the shell is provided with two longitudinal punching marks, the inner side of the shell is also provided with two transverse punching marks on two sides of the longitudinal punching marks, transverse tearing hands are arranged on the outer sides of the punching marks on two sides, and the transverse tearing positions are staggered.

The invention has the beneficial effects that: be equipped with the die-cut trace in cylindrical battery's inboard, be equipped with the mar in cylindrical battery's the outside, form an easily torn region, can come cylindrical battery easily to unpack apart through tearing the hand at the dismantlement in-process, improve battery dismantlement efficiency, make things convenient for the battery to retrieve, improve battery recovery efficiency. And the process is simple, and the upgrading cost of the existing process is low.
