In October 2022, Jiangsu Reliance Energy Tech. Co., Ltd. settled in Changzhou, Jiangsu—the “Capital of New Energy”—and launched the first phase of its high-rate lithium-ion battery cell R&D and manufacturing project in Changzhou Binjiang Economic Development Zone. The company is dedicated to the research, production, and sales of high-rate, high-energy-density, tabless, and large cylindrical lithium batteries.
With over a decade of deep expertise in high-rate, high-energy-density cylindrical batteries, Reliance Energy’s top management possesses comprehensive insights into markets, products, and technology, charting a clear course for the company’s growth. Its technical team combines a top-tier R&D group led by “world-class scientists” with a Japanese-style engineering team, achieving industry-leading capabilities in core areas such as materials, mechanisms, platform research, product design, process development, and equipment innovation. This ensures thoroughness and depth in product system planning. Embracing the Japanese philosophy of “extreme manufacturing,” Reliance Energy’s operational system excels in production management, equipment maintenance, engineering, and supply chain management, guaranteeing “zero tolerance” in manufacturing consistency.
Reliance Energy has successfully developed and begun small-batch production of the world-leading tabless cylindrical 21700 battery cell. This product breaks through the limitations of conventional tab structures, delivering exceptional performance. Compared to conventional designs, the tabless structure reduces internal resistance by 70% (2-4mΩ), enabling higher-rate discharge while lowering operating temperature rise by 30%. While conventional cells release only 50% of their designed capacity under 40A discharge due to overheating, Reliance Energy’s tabless cells achieve 100% discharge, boosting lifetime energy throughput by 80%. In extreme discharge tests, the cell sustains over 100A continuous discharge, providing robust power support for high-demand applications. With ultra-low impedance supporting ≥3C charging rates without compromising cycle life, the cell also achieves a “super-fast charge” from 0% to 80% capacity in just 10 minutes. Combining safety, endurance, rapid charging, longevity, and cost-effectiveness, this cell is poised to disrupt the market.
Reliance Energy’s vision—”Earning Global Respect Through Products”—aligns perfectly with high-end clients’ demand for premium solutions. Leading domestic and international partners, including Dartek, a top-tier power tool manufacturer, have collaborated with Reliance Energy to develop cutting-edge products. At a recent launch event witnessed by over 6,000 online and offline attendees, Dartek showcased tools powered by Reliance Energy’s cells, demonstrating the 10-minute “super-fast charge” to industry acclaim. On March 21st, Reliance Energy and Dartek solidified a strategic partnership based on “mutual benefit, stability, and efficiency.” Concurrently, international clients are actively evaluating Reliance Energy’s cells and developing platform systems tailored to tabless technology, fostering shared growth across the supply chain. Reliance Energy predicts that 2024 will mark the dawn of DC tools fully replacing AC tools, driven by tabless innovation.
Guided by reverence for markets, clients, and products, Reliance Energy is committed to empowering partners, delivering reliable solutions, and advancing sustainable development for a greener future.
