With the rapid development of world economy, new energy has already been the mainstream of the world, with the rapid development of the industry of our country, energy storage and new energy automobile, the demand for lithium battery will continue to climb. Meanwhile, with the rapid development of mobile phones, electric vehicles, photovoltaic solar energy, power tools, digital cameras, household energy storage and so on, the demand for lithium battery will continue to grow. The lithium battery concept is promising.

Lithium-ion batteries can be divided into consumer, power and energy storage types, depending on their use. For now, the development prospects of lithium batteries are mainly focused on power batteries and energy storage batteries, mainly used in electric vehicles and energy storage. Energy storage batteries and power batteries are not much different in technical principle, but in practical application, their performance and service life are also different.

Applications for power batteries include electric vehicles, electric bicycles and other power tools; Power lithium battery is a kind of mobile power supply with high energy density and high power density, and its service life can reach 1000-2000 times.

The application range of energy storage battery includes peak regulation, frequency modulation, renewable energy grid connection, micro grid and so on. Most energy storage devices do not need movement, so they do not need energy density and power density. Different energy storage schemes have different requirements for energy density. In battery materials, attention should be paid to the expansion rate of materials, energy density, the uniformity of electrode material performance, in order to achieve better service life and lower prices.

According to the shape of the product, power and energy storage system can be divided into cells, modules and components. The cell is the core component of the power battery, which can be assembled into a complete battery pack and finally applied to the new energy vehicle.

Power battery and energy storage battery are the most common battery types on the market at present, and with the progress of The Times, laser welding machine has become the first choice of major battery manufacturers, Xinde laser welding equipment because of its high-quality product quality, has been recognized by most professionals. Xinde Laser laser welding machine has various styles, whether it is power battery, energy storage battery, or square shell battery, there are welding equipment can be welded, but also a multi-purpose laser welding machine.
