According to the way of battery packaging, battery can be divided into three types, namely cylindrical battery, square battery and soft-pack battery. The unit energy density, dead weight, internal resistance, cycle life, safety performance and other aspects of soft-pack battery are far superior to the other three kinds of battery. Even if there are safety problems, soft-pack battery only expands and cracks, and will not explode because of the use of metal shell. But because of poor consistency, high cost, high production process, lithium battery laser welding machine manufacturer Xinde laser analysis most of the domestic battery manufacturers will choose the lower cost of the square battery when entering the market. Data show that in 2021, square battery market share reached 86.4%, soft pack battery is 7.4%.

PACK of new energy lithium batteries usually refers to packaging, packaging and assembly. For example, two batteries, depending on the user's needs, are combined into a special shape, which is the PACK. PACK is an important link in the production, design and application of the new energy lithium battery system, which is an important link linking the upstream production of batteries with the downstream automotive applications.

Curb carbon emissions, build a better home, new energy revolution is the general trend. In this context, many enterprises are transforming to green and new energy. Lithium-ion batteries for new energy vehicles and energy storage batteries have become the industrial focus of entrepreneurs.

In order to improve production capacity and accelerate market penetration, in recent years, domestic battery manufacturers have been trying their best, from land to factories, and then to tens of billions of private additions, all because of the rapid development of the new energy vehicle industry. However, at the industrial level, the crazy expansion of major battery enterprises is not only limited to the field of new energy, but also to the rapidly growing field of energy storage.

Why do lithium batteries use aluminum for their positive terminals and nickel for their negative terminals

Laser welding machine is a very popular welding equipment in recent years. In terms of materials, laser welding machines can be used to weld various metal plates of the same material, such as aluminum, iron, stainless steel and copper plates. And aluminum copper, stainless steel copper and other materials mixed welding. It covers far more areas than traditional welding methods.
