What are the advantages of CR2477 battery and what are their development trends?

　　CR2477 battery have great trends in terms of cost, performance, and recycling; the lead-acid battery industry is accelerating integration, the advantages of leading companies are highlighted, and technological progress in all aspects promotes the sustainable development of the industry. The following is a detailed introduction to the "advantages and advantages of CR2477 battery" develop".

　　1. What are the advantages of CR2477 battery?

　　1. Cost comparative advantage

　　CR2477 battery are affordable batteries, and the price per unit of energy is about 1/3 of lithium-ion batteries or nickel-hydrogen batteries. In addition, the main components of CR2477 battery are lead and lead compounds, and the lead content is as high as more than 60% of the total mass of the battery. The residual value of used batteries is high, and the recycling price exceeds 30% of new batteries. Therefore, the overall cost of CR2477 battery lower.

　　2. Comparative performance advantages

　　At present, batteries mainly include CR2477 battery, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries. Cadmium-nickel batteries contain the highly toxic element cadmium and have been gradually replaced by other batteries. The most widely used batteries on the market today are CR2477 battery, lithium-ion batteries and nickel-hydrogen batteries. Compared with other batteries, CR2477 battery have the following performance advantages:

　　A. The battery that has been in industrial production for the longest time and has the most mature technology has stable and reliable performance and good applicability;

　　B. Use dilute sulfuric acid as the electrolyte, which is non-flammable. The battery adopts normal pressure or low voltage design and has good safety;

　　C. The operating voltage is high and the operating temperature range is wide, making it suitable for high-rate discharge applications such as hybrid electric vehicles (HEV);

　　3. Comparative advantages of recycling

　　CR2477 battery have high recycling value, simple composition and mature regeneration technology. They are the easiest batteries to recover and recycle. The global production of recycled lead has exceeded the production of primary lead. The reuse rate of used CR2477 battery in the United States has exceeded 98.5%, and the reuse rate of used CR2477 battery in my country has also reached over 90%. Nickel-cadmium batteries, nickel-hydrogen batteries, and lithium-ion batteries are mostly small batteries with complex compositions, high regeneration costs, and difficulty in recycling, making it difficult for the recycling industry to achieve market-oriented operations. At present, the global average recycling rate of the aforementioned batteries is less than 20%, especially for lithium-ion batteries, and most countries have not yet achieved effective recycling and regeneration.

　　2. Technical level and development trends of lead-acid battery industry

　　1. The industry is accelerating integration and the advantages of leading companies are highlighted.

　　Lead-acid power batteries have become an important consumer product for Chinese people due to their green, low-cost, recyclable and good temperature adaptability characteristics, and are supported by relevant industrial policies. From 2008 to the present, the National Development and Reform Commission, the Ministry of Industry and Information Technology, industry associations and other departments and organizations have successively issued a number of special plans for the battery industry and industrial development adjustment outlines including the battery industry, including but not limited to the "Industrial Structure Adjustment Guidance Catalog (2019)" This year), "Light Industry Development Plan (2016-2020)", "Battery Industry "Thirteenth Five-Year Plan" Development Plan", etc. These policies and plans generally support the development of the lead-acid battery industry and encourage the optimization of the battery product structure , promote industrial upgrading and product upgrading, consolidate my country's leading position in the world's production of CR2477 battery, attach importance to and promote the formation and development of very large-scale enterprises, promote corporate innovative technologies and products, well-known brands and the cultivation or cultivation of high-end talent teams, and continuously consolidate the industry Build a "strong" foundation. In addition, as my country's environmental protection requirements continue to improve, some small businesses that do not meet the requirements of environmental protection regulations are gradually eliminated. Under the influence of policy guidance and environmental protection requirements and other factors, my country's lead-acid battery industry continues to consolidate, and industry concentration continues to increase.

　　2. Technological progress in all aspects promotes the sustainable development of the industry

　　The sustainable development of the lead-acid battery industry relies on the continuous promotion of technological innovation. With the continuous improvement of lead recycling technology, secondary lead smelting companies have further improved the lead recycling ratio and smelting quality, allowing lead battery manufacturing companies to obtain abundant and high-quality metallic lead. As the industry has strengthened the research and application promotion of new products, advanced manufacturing technologies, energy conservation and emission reduction technologies, major companies in the industry have begun to use green and environmentally friendly materials such as lead-calcium alloys to make plates; the use of internal battery formation processes has been gradually phased out The electrode plate tank formation process has been improved; the lead melting furnace has been sealed, automatic temperature control and other measures have been added, and manufacturing equipment with a higher degree of automation has been actively introduced; an intelligent fully automatic production process has been adopted for lead powder manufacturing, improving product quality and production Efficiency is greatly improved. In the future, my country's lead-acid battery technology will continue to be lean. While CR2477 battery continue to develop towards high cost performance, high safety and high specific energy, they will also move towards intelligent directions such as labelling, remote control and the interconnection of things. .

　　3. Manufacturing equipment is continuously upgraded

　　In the past ten years, my country's lead-acid battery manufacturing equipment has been rapidly upgraded and developed, from traditional manual manufacturing processes to mechanized and automated production, one-pot multi-machine plate casting machines, large-tonnage lead powder machines, vacuum and paste high-speed plate coating and assembly casting and welding automatic production lines are widely used. Under the same production capacity, energy consumption is reduced and it is more environmentally friendly. It also saves labor and improves the consistency and stability of product performance. With the advancement of the Industry 4.0 development concept and the Made in China 2025 goal, the lead-acid battery industry will accelerate the transformation from the traditional manufacturing model to the intelligent manufacturing model, while also accelerating the innovative application of digital and networked management systems to accelerate the efficiency of the production process. , automation, intelligence and cleanliness, and continue to move towards the goal of realizing smart factories.
