Lithium battery R&D and production is China’s strong advantage. Even the United States cannot compare with China. Currently, more than half of the world’s lithium batteries are produced in my country. The technology is relatively mature, but some key links also require strong technical expertise. Technical requirements, such as: battery sealing and welding, which play a great role in the safety of the battery!

Due to actual application needs, the requirements for battery production processes are getting higher and higher. Batteries are getting thinner and smaller, and their electrical energy capacity will increase accordingly. Therefore, the technical difficulty of sealing welding becomes more and more difficult. Taller.

During battery welding, we must take into account the characteristics of the battery material, such as password welding strength, metal corrosion resistance and fatigue resistance, which are the main safety factors that affect the battery. This is something that needs to be considered when welding the battery. The major parts of the battery welding include Cover sealing welding; tab welding, and battery module welding and other parts, there are some special ones such as: tab welding is nickel to aluminum material welding, which is more difficult.

Batteries are made of a variety of materials, and battery laser welding machines often face welding processes between these different materials, such as zinc, aluminum, copper, nickel, titanium and other alloy materials. The welding of these materials can only be welded by laser welding machines. Other traditional welding methods cannot do it. Battery laser welding machines are the only choice for welding all parts of the battery. In this regard, SHINHOP laser welding the performance of the device is particularly outstanding!
