Development trend of lithium battery equipment manufacturing industry

The lithium battery equipment industry provides downstream lithium battery manufacturers with professional production equipment and services that meet technical standards. https://www.aceymachinery.com/ integrates multidisciplinary technologies such as machinery, electronic power, automatic control, chemical materials, and information technology. It is technology-intensive, capital-intensive, and professional. Strong, high degree of customization features.Lithium battery equipment has an important impact on the production process, product consistency, performance stability and quality of lithium batteries. The improvement of the technical level of lithium battery equipment is an important basis for the improvement of downstream lithium battery technology and performance. Lithium battery equipment manufacturing industry is the lithium battery industry chain important parts of.

Lithium battery production process and equipment

The basic structure of the current mainstream lithium battery is cell-module-battery pack, in which the cell is the smallest energy unit. Lithium battery manufacturing is mainly composed of three core production and assembly links of batteries, modules and PACK. Among them, cell manufacturing is the most critical and most valuable link in the lithium battery production process. The battery cell is assembled from positive electrode material, negative electrode material, electrolyte and separator, the battery cell is the core component of PACK. The production process of lithium batteries in different forms (such as soft pack batteries, square batteries and cylindrical batteries, etc.) is roughly the same. It can be divided into three stages: the front process (electrode production), the middle process (cell assembly) and the back process (cell activation). Corresponding to the corresponding process, the cell production equipment can also be divided into front-end equipment, middle-end equipment and back-end equipment. After the latter process is completed, the batteries are ready for use, and then the batteries are assembled into finished battery packs through the module and PACK production lines. From the perspective of value distribution, the value of front-end, middle-end, back-end equipment and module PACK assembly lines accounted for about 35%, 30%, 25% and 10% respectively. In recent years, downstream terminal products have increasingly higher requirements on the energy density, safety and stability of lithium batteries, resulting in accelerated iterations of lithium battery technology updates. At present, the development of lithium battery technology focuses on improving specific energy and optimizes products from two directions: lithium battery materials and production processes. On the one hand, lithium battery materials undergo gradual innovation, and lithium batteries evolve from liquid, semi-solid to all-solid. On the other hand, start with process improvement, optimize the manufacturing process, and optimize the battery system. In order to adapt to the new materials and new process changes of lithium batteries, lithium battery equipment needs to be adjusted and improved accordingly, which promotes the increasing demand for lithium battery equipment updates and brings greater development space for the lithium battery equipment manufacturing industry.

With the rapid development of the new energy vehicle industry, large-scale manufacturing of lithium batteries and insufficient high-quality manufacturing capabilities have become bottlenecks restricting the development of the lithium battery industry and electric vehicles. It has an adverse impact on the position of lithium batteries in the new energy vehicle industry. In recent years, under the background of large-scale expansion of lithium battery production, intelligent manufacturing equipment and production lines have become an important guarantee for high-efficiency, high-precision, high-quality and stable production of lithium battery manufacturers. At the same time, the competition in the lithium battery manufacturing industry is intensifying, and is being squeezed by the rising price of raw materials on the supply side and the reduction of subsidies from OEMs on the client side. Improving efficiency and reducing costs have become urgent needs for battery manufacturers. Cost control and quality improvement have led more and more lithium battery manufacturers to carry out intelligent transformation and upgrading of traditional production lines, and the demand for intelligent manufacturing equipment and production lines continues to increase.

From the perspective of future development trends, on the one hand, the deep integration of lithium battery equipment with information technology, automation control, artificial intelligence and big data technologies will continue to improve the automation and intelligence level of the production process. On the other hand, the equipment in each link of lithium battery will show a trend of integration, such as die-cutting and laminating integrated machine, rolling and slitting integrated machine and drying and liquid injection integrated machine, etc., by integrating several production links into one equipment to complete, improve processing The level of automation and continuity of the process. In addition, the transformation of lithium battery equipment from stand-alone sales to segmented integration and then to whole-line integration helps downstream customers shorten the production line construction cycle and improve the synergy, compatibility, consistency and overall efficiency of the production line. As an important basis for helping companies in the battery manufacturing industry improve production and maintenance efficiency, reduce production costs and improve product quality. In the future, the market capacity of intelligent, integrated and integrated lithium battery equipment will maintain a continuous growth trend, and the competitive advantages of lithium battery equipment manufacturers with corresponding equipment supply capabilities will be highlighted
