in the first half of 2024, global sales of new energy vehicles exceeded 7 million units. chinese brands performed impressively, not only occupying 12 seats in the top 20, but also 6 companies among the top ten, with an overall market share of 69%.

when it comes to new energy, lithium battery is undoubtedly the most dazzling pearl. in the first half of 2024, the total installed capacity of power batteries in the world reached 364.6 gwh, a year-on-year increase of 22.3%; among them, six chinese companies ranked among the top ten in the world with a market share of 64.9%. leading companies such as catl and byd are leading the development direction of the global lithium battery industry with their outstanding technical strength and market share.

the collective rise of catl and others is due to my country's complete industrial chain and cost-tech advantages, as well as the "group fight" of many scientific and technological teams and enterprises behind the new energy industry chain. the technological innovation of these industry chain segmented enterprises has provided a driving force for the continuous progress of new energy development, and they are the core driving force for the high-quality development of china's energy industry.

in the catl smart factory, i found a modern battery slurry conveying and cleaning system, which is mainly responsible for the conveying and cleaning of high-value lithium battery slurry. the system comes from a company in guangdong province, guangzhou shaxi mechanical and electrical engineering technology co., ltd., which is a technology-innovative company focusing on fluid conveying and cleaning system solutions, and is committed to providing users with continuous innovative solutions in the battery new energy industry.

speaking of the pigging system, it was originally used in the daily chemical industry, mainly using pigging balls and control systems to recover high-value cosmetics in pipelines. its working principle is that when the pigging ball is pushed by compressed air, it quickly passes through the pipeline, thereby achieving the goals of filling and recovering high-value raw materials in the pipeline. because it makes a long and sharp sound when working, people also call the pigging ball "pig head".

in 2016, guangzhou shaxi mechanical and electrical engineering technology co., ltd. introduced the pipe cleaning ball system into the battery new energy industry for the first time through scientific research and technological innovation, and it was successfully applied in catl (patent number: 2l201720995156.7); in 2021, the company once again independently innovated the design, successfully developed and launched an automatic two-way reciprocating pipe cleaning system, ushering in the global pipe cleaning ball system 2.0 era.

what value can a small cleaning ball system achieve? first, the equipment has the function of recycling anode and cathode slurry, which reduces the waste of raw materials and increases the company's profits; at the same time, the equipment reduces the overflow of dry slurry microparticles and metals, greatly improving the company's product quality; third, it can reduce cross-contamination between different raw material formulas, improve the level of equipment automation, and reduce labor costs; finally, it reduces the wastewater and waste nmp from cleaning pipelines, playing a role in protecting the environment.

china has tens of thousands of small and micro science and technology enterprises. at present, they are constantly accelerating the transformation of scientific research results and continuously promoting the transformation of major scientific and technological achievements into real productive forces. the huge new productivity hidden behind small science and technology teams is constantly helping to improve the technical level in the new energy field, helping leading enterprises to actively cultivate new technologies, new industries and new business formats, and provide power for the iterative upgrading of engineering applications.

in fact, china's new energy industry chain covers multiple related sub-sectors, forming a complete and highly competitive ecosystem, from upstream raw materials and key components, including rare earths, lithium, battery materials, etc., to midstream equipment manufacturing and system integration, including battery packs and bms systems, energy storage system integration, etc., to downstream applications and services, such as new energy vehicles, energy storage power stations, etc., each link is crucial. the reason why china's new energy can stand at the top of the world is inseparable from the balanced development of the entire industry chain, and more importantly, it is inseparable from the product technology innovation and successful scientific research transformation of specialized and new scientific and technological enterprises such as guangzhou shaxi company.

industrial chain supply is the lifeblood of the industrial economy. only with a complete new energy industry chain supply chain can we provide strong support for the country's green energy development.contribute chinese wisdom and solutions to the global new energy revolution.
