In the new energy industry, the saying goes, "Without lithium, progress is impossible; with lithium, the world is within reach." A number of battery manufacturers have harnessed their core competencies in technological innovation and intelligent manufacturing to drive breakthroughs in their respective fields. Shenzhen Cham New Energy Co., Ltd. (hereinafter referred to as "Cham New Energy") is one such pioneer.

Recently, Cham New Energy achieved a significant milestone at its Mianyang base by launching the country's first fully automated, high-speed production line for wide-temperature quasi-solid-state large cylindrical batteries. This production line, which embodies over 20 years of Cham New Energy's technical expertise, is capable of producing lithium iron phosphate batteries, sodium-ion batteries, lithium manganese iron phosphate batteries, and quasi-solid-state lithium iron phosphate batteries in various sizes and capacities. This development is set to play a pivotal role in advancing the equipment manufacturing industry in Mianyang and across Sichuan Province.

Cham New Energy's Technological Upgrade Addresses the "Dual Demand" New Normal

Cham New Energy's Mianyang production base represents a significant strategic investment for the company in Southwest China. The base is initially planned to house two production lines: a 32-series line and a 46-series line. These lines, supported by the company's advanced material systems in lithium iron phosphate, sodium-ion, manganese iron phosphate, and quasi-solid-state technologies, will be capable of producing batteries of various sizes and capacities. Once the two production lines in Mianyang reach full capacity within the first year, the annual output is expected to hit 5GWh, with the first phase fully operational at 10GWh. Upon completion, Cham New Energy's products will meet the needs of a wide range of applications, including small electric vehicles, home energy storage, communications, passenger cars, special vehicles, military, and aerospace. In recent years, batteries on the market have struggled to balance performance and cost, with safety incidents drawing significant attention from both the industry and society. Addressing these industry pain points, Cham New Energy's Mianyang production base has enhanced its proprietary research and development systems, aiming to strike a balance between performance, quality, and cost while providing tailored solutions for customers. In the two-wheeler sector, Cham New Energy has developed lithium manganese iron phosphate batteries with several advantages, including high energy density, enhanced safety, and low cost. These batteries boast an energy density of over 200Wh/kg and can pass extreme safety tests such as nail penetration, while their cost per watt-hour is lower than that of traditional lead acid batteries, making them a top choice for cost-conscious customers in the two-wheeler market. In the sodium-ion battery field, Cham New Energy has developed batteries that support 4C fast charging, capable of charging from 10% to 80% in just 15 minutes at 25°C, alleviating users' charging anxiety. Additionally, these sodium-ion batteries can charge at -20°C and discharge at -40°C with a capacity retention rate of over 90%, meeting the demands for outdoor low-temperature usage in high-latitude and high-altitude regions. Cham New Energy's large cylindrical batteries feature full-tab technology, which significantly reduces internal resistance and heat generation, leading to a 90% reduction in internal resistance. These batteries offer uniform heat dissipation, zero expansion, and enhanced safety. To meet industry demands, Cham New Energy is also developing a 120ppm 46-series cylindrical battery production line, with manufacturing costs 20% lower than traditional prismatic batteries. Furthermore, Cham New Energy's quasi-solid-state lithium iron phosphate batteries exhibit remarkable safety performance, with no thermal runaway during nail penetration tests and a peak temperature reduction of 40°C compared to conventional lithium iron phosphate batteries. This makes them ideal for large-capacity batteries and large series-parallel battery packs, offering superior safety.

"Digital Intelligence" Drives Efficiency: Cham New Energy Builds a Transparent Factory

Cham New Energy's Mianyang production base is a fully AI-driven smart factory, equipped with an independent intelligent computing center capable of processing and analyzing over 500 terabytes of product process data. The factory employs an all-optical networking technology, achieving millisecond-level latency and rapid networking, significantly boosting production efficiency. In an increasingly competitive battery industry, quality remains the enduring threshold for customers. Cham New Energy recognizes that achieving smart industrial production and lean manufacturing, surpassing Six Sigma factory standards, is key to maintaining its industry leadership. To this end, Cham New Energy has taken the lead in adopting "high-efficiency slurry preparation" technology in its production process design. By utilizing a rotor-stator dispersion unit, the company improves dispersion effectiveness and accelerates slurry preparation efficiency, reducing process time by 60% and energy consumption by 80%. The core coating process employs a fully automated surface density closed-loop control system, enabling real-time monitoring and adjustment, reducing the likelihood of abnormalities during coating, and improving product consistency and yield. The assembly line features high-speed, stable cam turret mechanical transmission technology, offering high precision and speed. The core full-tab process employs inverted flattening and extreme dust removal technology to ensure high-quality full-tab procedures. The entire production line can track individual battery cells and conduct online automatic quality inspections. With stringent environmental controls and fully digitalized, intelligent monitoring across all processes, Cham New Energy strives to achieve the highest production efficiency in the industry, aiming to increase product yield to 99%. Cham New Energy actively collaborates with internationally renowned companies like Siemens to co-develop digital production line manufacturing solutions. By introducing Siemens' latest MES system, Cham New Energy monitors over 2,500 data points, achieving a 100% online equipment rate and generating vast operational and manufacturing data. This deep integration of IT and OT ensures full traceability of both individual battery cell quality and carbon footprint throughout the entire process. During production, an efficient collaborative ecosystem is formed between personnel, equipment, the cloud, and customers, ensuring product reliability, consistency, and safety.

Cham New Energy Takes Another Leap Forward, Expanding Its Collaborative Landscape

As an early entrant and a leading player in the domestic large cylindrical battery industry, the launch of Cham New Energy's Mianyang base marks another significant step forward in intelligent manufacturing. It also signifies the company's readiness to adapt to new dynamics and embrace the next phase of growth, setting the stage for a transformative "metamorphosis." Cham New Energy recognizes the importance of synergistic growth with both upstream and downstream partners. Amid the global surge in the new energy industry, the company's international collaboration network continues to expand. By forging strong alliances with industry giants like Huawei, Belkin, and BYD, Cham New Energy has built a world-class network of partners with a global reach and profound influence. At the same time, Cham New Energy remains keenly attuned to market demands, demonstrating agility in adjusting its product strategy to meet the diverse needs of both domestic and international customers. Looking ahead, as the global demand for green and efficient energy solutions continues to skyrocket, Cham New Energy's strategic initiatives are poised to attract even more attention, accelerating the company's brand elevation and industry impact.
