With the development of new energy vehicles and energy storage market, large monoblock lithium batteries, as a high-performance, high-energy density power source, are receiving more and more attention in the fields of electric vehicles, energy storage and aviation. In the manufacture of large monoblock lithium batteries, welding is a critical step. This article will provide you with a detailed introduction to the characteristics of large monomer lithium batteries, welding methods and future development trends.

Large single lithium battery welding

The characteristics of large single lithium batteries

Large-cell lithium-ion batteries mainly refers to the capacity of more than 100Ah single-cell lithium-ion batteries, with the following characteristics.

High energy density: compared with other types of batteries, large single-cell lithium batteries have a higher energy density, which can provide more durable power support.

Good safety: large single lithium battery development has relatively high safety technology performance, using a variety of information security management measures to avoid battery short circuit, overcharge, overdischarge and other issues.

Long cycle life: Large monomer lithium battery has a long life and can be recycled thousands of times, which greatly reduces the cost of battery replacement.

Production Difficulty:Due to the large size, heavy weight and internal complexity, large monoblock lithium batteries are difficult to produce and require advanced production equipment and technology.

Welding method of large single lithium battery

The welding method of large single lithium battery is slightly different from the ordinary lithium battery,battery pilot machine the common welding methods are as follows.

Spot welding method

Spot welding is a traditional Chinese welding method, and is also the most widely used welding technology in China. It adopts the principle of resistance heating, through the different current and resistance can promote each other's role, making our welding structure material heating and melting, forming a solid connection. Spot welding method is suitable for the manufacture of some large battery components, such as electric vehicle batteries, energy storage batteries.

Gas Shielded Arc Welding

Melting electrode gas shielded arc welding is a welding method that uses an inert gas to protect the surface of the metal being welded. The invention can avoid the effects of contaminants such as oxidation on the weld, thereby improving the quality and stability of the weld.battery laser welding machine This melting electrode gas shielded arc welding welding method is suitable for welding of large single lithium batteries, and can effectively improve the welding quality.

Third, the future development trend of large single lithium battery welding

With the growing market demand for large single lithium batteries, large single lithium battery welding technology is also constantly innovating and developing. In the future, the welding of large single lithium batteries will be developed in the following areas.
