On July 9, power battery newcomer Honeycomb Energy will hold a stacking era strategic planning and product launch conference in Baoding with the theme of "Leading the Stacking Era and Protecting Core Safety" to release a series of power battery products based on high-speed stacking technology to the industry. For electric vehicles, power batteries are the key and the focus of attention from all walks of life. Power batteries directly affect the safety performance, cruising range, charging time, cycle life and cost of electric vehicles. Since April this year, spontaneous combustion accidents of electric vehicles have occurred frequently, causing public doubts about the safety of electric vehicles and triggering heated discussions in the industry. The power battery market calls for changes in production processes. Currently, there are two main types of battery production processes on the market: lamination and winding. Traditional lamination process batteries are mainly soft-packed cells. The lamination efficiency has been at a low level due to equipment and other reasons. The production efficiency of the winding process is higher. However, in the face of the large-scale development of electric vehicles, limitations are becoming more and more The more obvious it is, there are problems such as poor internal interface uniformity, pole piece wrinkles during circulation, and high expansion force, which intensify the safety risks of electric vehicles. Therefore, the market urgently needs the emergence of new battery production processes to break this situation. In order to launch more cost-effective and safer batteries, major battery manufacturing factories are investing money and manpower in developing new technologies. As a battery manufacturer with the DNA of a car company, Honeycomb Energy has outstanding advantages in automotive battery research and development. A large number of core talents have backgrounds in the automotive industry, allowing Honeycomb Energy to understand cars better than manufacturers that started out with pure battery technology since its birth. Demand, the product platform is also designed according to the needs of automobiles in different application scenarios. Honeycomb Energy has in-depth cooperation with the technical teams of top European car companies and built China's first factory in Jintan, Jiangsu in accordance with world-class standards. This is the world's first intelligent battery cell manufacturing factory that adopts "high-speed lamination technology" on square aluminum shell batteries. It integrates intelligent systems such as intelligent distribution, digital signage and analysis, quality traceability and analysis, and digital quality inspection. The factory covers an area of 800 acres, with an investment of 10 billion yuan and an output value of 20 billion yuan. It mainly produces aluminum-cased square batteries. The factory was constructed in two phases, with a total planned production capacity of 20GWh. High-speed lamination process empowers square lamination batteries. The high-speed lamination process is Honeycomb Energy's innovative change in the traditional lamination process, which greatly improves production efficiency. At this stage, Honeycomb Energy has applied this process to square aluminum shell batteries. The efficiency of the traditional lamination process is 1S per piece in a single station. The first phase of the Honeycomb production line has been improved to 0.6S. The second phase can achieve 0.45S high-speed lamination. And an ultra-high-speed lamination process of 0.25S in a single station is being developed, which is expected to It perfectly solves the efficiency problem of the lamination process and even surpasses the efficiency of the winding process. Compared with traditional winding process batteries, high-speed lamination process batteries have multiple advantages: higher space utilization at corners, energy density can be increased by 5%; lower deformation and expansion throughout the life cycle, and cycle life increased by more than 10%; The edge structure is simpler, the structure adaptability is better, and the battery safety is higher. Square stacked batteries based on high-speed stacking technology have more advantages in space efficiency and safety, and are expected to become a mainstream demand product for the large-scale development of electric vehicles. This new era of power battery development based on the new S3 standard of Full Cell Energy is called the "stack era" by the industry. The future has come and power batteries have entered the stacking era. Looking back at the development of lithium batteries, it is not difficult to find that the 1.0 era of lithium batteries was created by Sony Corporation of Japan. Its winding process lithium batteries are widely used in 3C consumer electronics such as mobile phones, cameras, and laptops. field. The lithium battery 2.0 era is the era of traditional coiled batteries. This battery has made great progress compared to the Sony era and has begun to be used in cars, but it is essentially an improved version of 3C lithium batteries. Next, power batteries will enter the 3.0 era, which is the power battery stack era - a new lithium battery era characterized by the application of high-speed lamination technology. Compared with batteries in the 1.0 and 2.0 eras, batteries in the 3.0 era have the "three highs" advantages of high safety, high energy density, and high cycle life. At the same time, they can meet the clear needs of electric vehicles for large size and large capacity batteries, and have "three highs". "Next generation power battery". At the 6th China (Qingdao) Lithium Battery New Energy Industry International Summit Forum held in November 2018, Dr. Ma Zhonglong, deputy general manager of Honeycomb Energy, revealed, “We have made significant achievements in high-nickel cathodes, silicon-carbon anodes, and cobalt-free cathodes. Progress and technical roadmap are progressing steadily. At the same time, we have also made sufficient technical reserves for forward-looking battery technologies such as lithium-rich cathodes, all-solid electrolytes, lithium metal anodes, lithium-sulfur, and lithium-air batteries to ensure long-term product competitiveness." It is also understood that Honeycomb Energy has also planned Super-i super integrated modules and other highly integrated, lightweight Pack designs and BMS designs in terms of system integration to meet the needs of price-sensitive models. According to Honeycomb Energy's plan, by 2025, the company will contribute 100GWh of production capacity to the world, including 60GWh of production capacity to China. It has the ability to stably supply domestic and foreign mainstream OEMs, and is determined to join the global high-end OEM supporting system and become A world-class provider of power and energy storage battery systems.
