Lithium Battery Disassembly and Fault Analysis during Disk Setting

Lithium Battery Disassembly

Lithium battery disassembly can be done in several ways but what is the purpose behind it? This article has been written to understand the disassembly process of the lithium battery that allows the analysis of the chemical composition of the battery, as well as the analysis of any overvoltage fault that may occur during the disk setting process.

Lithium Battery Disassembly

The disassembly of the battery can be done in several ways, depending on the type of battery, such as a lithium-ion battery or a lead-acid battery. The first step in the disassembly process is to remove the battery cells. This can be done by either removing the top cover of the battery or by removing the cells in the middle of the battery. Once the cells have been removed, they can be examined for any signs of corrosion, rust, or other damage. The next step is to examine the chemical composition of the cells.

This can be done using a combination of X-ray diffraction, electron microscopy, and other analytical techniques. By examining the chemical composition, it is possible to identify any overvoltage faults that may have occurred during the disk setting process. The last step in the disassembly process is to clean the cells and the battery casing.

This involves removing any debris or dirt that may have accumulated during the disk setting process. Once the cells and casing have been cleaned, the battery can then be reassembled and tested for any remaining faults.

Overall, the lithium battery disassembly process is an important step in the analysis of an overvoltage fault during the disk setting process. By examining the chemical composition of the cells and cleaning the casing, it is possible to identify and isolate any faults that may have occurred.

Claw overpressure

Claw overpressure is a phenomenon that occurs in the disassembly of lithium-ion batteries. When a lithium-ion battery is disassembled, the cells within the battery can be exposed to high levels of pressure. This pressure can cause the cells to swell, resulting in a “claw overpressure” effect. This phenomenon can cause the cells to become distorted or even rupture, leading to potential safety hazards. To prevent this, it is important to ensure that the appropriate tools and procedures are used when disassembling lithium-ion batteries and that the cells are handled with care.

Location of the battery, matching of claws and battery position, abnormal claws

The battery is typically located between the battery contacts and the back of the device. The battery contacts should be aligned with the corresponding contacts on the device, otherwise, the battery may not fit properly or may not make a proper connection. If the battery has abnormally shaped claws, they should be carefully removed to ensure that the battery is able to be safely removed from the device.


1. Accuracy deviation of the claw clamping body

The accuracy of the claw clamping body in Lithium Battery Disassembly can range from 0.01-0.1mm. The accuracy deviation depends on the quality of the claw clamping body and the material used in its production. High-quality claw clamps made with high-precision materials can have an accuracy deviation of 0.01mm, while lower-quality claw clamps may have an accuracy deviation of up to 0.1mm.

2. Poor design of the claw itself

The design of the claw in a lithium battery disassembly device is a critical component of the entire system. Poorly designed claws can lead to damage to the battery, as well as a time-consuming and inefficient process. Poorly designed claws can have sharp edges that can cut into the battery, cause it to slip, or have insufficient gripping power. It is important to ensure the claw is designed for the specific size and shape of the lithium battery. It should also be designed with smooth surfaces to reduce the likelihood of damage to the battery. Additionally, the claw should be designed to retain a secure grip on the battery, even when the disassembly process is complete.

Abnormal use process of claws

  • Before starting the disassembly process, safety equipment should be worn and the environment should be checked to ensure it is safe for operation.
  • Insert the claws into the seams of the battery and press them gently to open the battery.
  • Carefully remove the claws from the battery and check for any signs of damage to the battery.
  • If necessary, use a screwdriver to remove any small screws holding the battery in place.
  •  Pull the claws apart to separate the parts of the battery.
  • Place the separated parts in a safe area away from any sources of heat or flame.
  • Dispose of the battery components according to local regulations.


This article concludes a few points before starting the process of claws along with its properties to retain a secure grip on the battery and to reduce the chances of damage to the battery, even when the disassembly process is completed.
