In February 2022, GAC Aean sold 8,526 vehicles, with a year-on-year growth of 163%; Ideal Automobile delivered 8,414 units, up 265.8% year on year; Nezha delivered 7,117 vehicles, up 255% year on year; Xiaopeng Motor delivered 6,225 units, up 180% year-on-year; Nio delivered 6,131 smart electric vehicles, up 9.9% year on year; Zerorun delivered 3,435 vehicles, up 447% year on year; Krypton delivered 2,916 units, with a cumulative delivery of 12,453 units. Through the above series of data, we can draw a conclusion: in general, since the rise of the new force of car manufacturing in 2015, 2017, has made great progress, the order volume is constantly rising.

According to the battery packaging, can be divided into three categories: cylindrical type, square type, soft package type. Cylinder, square, soft package of these three packaging methods, domestic and foreign manufacturers of cylindrical type, square type, soft package are very different. Japanese manufacturers mainly use cylindrical batteries. Panasonic's 18650 cylindrical battery has been widely assembled in electronic products around the world, while Tesla is also moving towards providing cylindrical batteries for electric vehicles. Chinese companies such as Ningde Times and BYD follow a square path.

As we all know, the core of new energy vehicles is battery, and lithium is the core metal element of battery. No matter it is ternary lithium battery, or lithium iron phosphate battery, or solid-state battery in the future, lithium is indispensable. As the production of new energy vehicles increases, so does the production of lithium batteries. Thus set off a "have" lithium "all over the world" upsurge. So why does it happen? There are two main reasons.

Recently, oil prices rose again at 24:00 on March 17. From the end of last year to March this year, oil prices have risen six times, and the price of finished products has skyrocketed to the 9 yuan level. The sharp rise in oil prices has given fuel car owners mixed feelings about buying an electric car. In general, the average use cost of electric vehicles is lower. If the cost is calculated only in terms of fuel consumption and power consumption, electric vehicles are undoubtedly a more suitable choice. Fuel cars run on fuel consumption, while electric cars run on rechargeable batteries. Battery is used to store electricity, electric vehicle battery is a power battery, is also a kind of energy storage battery. The skyrocketing oil price has brought the new energy industry to a new height, and the energy storage industry is one of the important links.

After several generations of technical innovation, laser welding machine is more and more widely used. There are many manufacturers of lithium battery laser welding machine on the market, and the quality is uneven, so that some customers don't know how to start. How to choose cost-effective lithium battery laser welding machine?

With the development of industry, traditional electric welding and argon arc welding have been gradually replaced by more convenient laser welding. At present, the two most important laser welding machines and hand-held laser welding machines are the most widely used in the market. The reason why it can win the recognition of the majority of the market is that it breaks through the restrictions of the workbench and is flexible and convenient to use. And the welding effect is good and high efficiency, does not need too much technology, ordinary female workers can also easily operate.

This is a trillion-level industry. According to the research report of brokerages, the market size of energy storage is estimated to be tens of billions from the power generation side, and the energy storage market is estimated to be hundreds of billions from the power grid side. If measured from the user side, the market will reach trillion-level. In the face of such a huge cake, a number of listed companies have already carried out depth layout.
