Summary The company specializes in the production and sale of lithium batteries, including ternary lithium, lithium iron phosphate, and lithium titanate batteries, which are used in various applications such as power systems and energy storage. With 43 automated production lines, the facility is highly efficient, and the company expects its annual battery capacity to reach 1 billion watt-hours by 2017. This expansion reflects the company's strong market position and technological capabilities. To promote technological innovation and enhance brand value, the company participated in the 2017 Golden Engineering Golden Globe Awards, a recognition that highlights the achievements of Chinese lithium battery enterprises. Shilian Changyi Huai'an Technology Co., Ltd. was one of the key participants, showcasing its progress and contributions to the industry. As a national high-tech enterprise, the company has a strong focus on research and development, with 78 R&D teams comprising 2 doctors and 2 returning experts, making up 18% of the workforce. Its technology leader, Zhang Guiping, has been at the forefront of China’s lithium battery industry since the early days, working alongside companies like BYD. He has led several significant military battery projects, such as those for stealth fighters and patrol vehicles, demonstrating the company's advanced technical expertise and innovation capability. Annual Innovations/Bestsellers: Cylindrical Lithium-Ion Battery The solid-state lithium battery power solution features high energy density, excellent safety performance, high assembly efficiency, and low cost—equivalent to more than 20 small-capacity batteries in one. It also offers efficient battery pack management. With international patents under its name, this product is well-positioned to compete with global leaders, helping to expand the company's international footprint and elevate the overall competitiveness of China's power battery industry. Compared to large-scale products like the 18650 and 21700 cells produced abroad, the company’s cylindrical battery offers superior performance and strong market competitiveness. The surface junction structure is an innovative battery design developed by the company, holding invention patents in both Japan and the U.S. This breakthrough has broken the intellectual property monopoly held by Japanese and South Korean companies, marking a major milestone in China’s battery industry. It has significantly contributed to closing the technological gap between China and leading battery nations. The cylindrical lithium battery using the face junction structure offers three main advantages: The inventive battery junction structure involves a unique process where copper or aluminum foil with uncoated active material (light foil area) is formed at both ends of a cylindrical winding body through continuous oscillation. The ultrasonic high-frequency oscillation head shapes and pressurizes the foil body, allowing them to intertwine and make close contact, forming a "face junction" structure. This design ensures high safety; even in extreme cases, the surface junction can block air from entering the active material when the casing is damaged, greatly enhancing battery safety, as shown in the image below: The battery junction structure allows full utilization of the current collector's heat dissipation, effectively reducing internal resistance by about 20% compared to other similar batteries. This results in lower temperature rise during discharge (less than 10°C at 2C, less than 5°C at 1C), offering fast charging and high-rate discharging performance. The design also simplifies the production process by avoiding complex steps such as gap coating and multiple pole welding. The close contact between positive and negative electrodes and the separator improves consistency and efficiency. With a high level of automation, it supports the transition to Industry 4.0 smart manufacturing and has been recognized as a model intelligent workshop in Jiangsu Province. The use of pole through holes and plugs eliminates the need for drying rooms, enhancing production safety and lowering costs.
