Introduction
At The Battery Show Europe 2025, held from June 3-5 in Stuttgart, Germany, Yantai Leawat-Power Technologies CO., Ltd. captured the attention of industry leaders and enthusiasts alike. As a frontrunner in large cylindrical battery technology, Leawat showcased its latest advancements in battery design, particularly emphasizing its revolutionary 46-series large cylindrical batteries. This new battery line not only demonstrates remarkable improvements in charging speed, safety, and adaptability but also reinforces Leawat's significant role in the expanding global energy storage and electric mobility sectors.
Innovative Technology on Display
Leawat's presentation featured its groundbreaking "full-current-path" and "tab-less" design concepts. This innovative approach eliminates traditional welding points, reducing internal resistance by an impressive 20%. Such a design breakthrough allows for ultra-fast charging, which is crucial for electric vehicle (EV) users globally, who often cite long charging times as a primary concern.
Additionally, the batteries incorporate a sophisticated thermal-electrical decoupling system equipped with a single-side exhaust valve positioned at the bottom. This function ensures efficient heat dissipation and a consistent temperature distribution across the cell, reducing thermal risks. The design also integrates advanced micro-arc suppression technology to lower the chances of thermal runaway, fully complying with international safety standards like IEC62619.
Exceptional Performance Features
The 46-series batteries are characterized by their "Four High" attributes:
1.
High Energy Density: The unique "One-Unit stacking integration" design achieves over a 5% improvement in energy density at the system level.
2.
High Power Output: These batteries can support ultra-high discharge rates of up to 50C, making them suitable for demanding applications such as electric vehicles, drones, and industrial robots.
3.
High Safety Assurance: Innovative assembly techniques and self-gravity-assisted methods help reduce the risk of foreign matter intrusion by 75%, significantly enhancing safety.
4.
High Environmental Adaptability: Thanks to self-developed thermal equilibrium technology, the batteries function effectively in temperatures ranging from -40°C to 60°C, ensuring reliable performance in varied climates.
Global Ambitions and Market Prospects
Leawat's products have already seen an enthusiastic market reaction in China and are drawing attention from European automotive manufacturers and energy storage companies. The firm is poised to provide standardized cylindrical cells as well as tailored system solutions for several sectors, including:
- - Electric Mobility: Applications in high-end electric vehicles, two-wheelers, and electric vertical take-off and landing (eVTOL) aircraft.
- - Energy Storage: Solutions for utility-scale projects, commercial/industrial storage, and residential installations.
- - Smart Equipment: Catering to robotics sectors (like service robots and construction machinery) along with portable power applications.
Plans for Expansion
Leawat is actively engaged in a 25GWh large cylindrical battery project, featuring a 180PPM high-speed production line, which is acknowledged as the fastest in China. The initial phase, with a capacity of 4GWh, has already yielded promising responses in the Chinese market. The company has set an ambitious target to reach full 25GWh capacity by 2027, aiming for annual sales exceeding ¥15 billion (approximately $2.1 billion).
Mr. Feng Zihao, Vice General Manager of Leawat, expressed excitement about their global launch. "We are eager to present our technologies worldwide and collaborate with partners to facilitate the clean energy transition. Our dedication to innovation, safety, and expandability positions Leawat as a vital contributor to the future of the lithium battery industry,” he stated.
Conclusion
In conclusion, the advancements showcased at The Battery Show Europe 2025 not only highlight Yantai Leawat-Power Technologies' commitment to innovation in battery design but also signify a pivotal shift in the industry towards safer, more efficient energy storage solutions.
