「极耳无界 能量登峰」：睿恩21700-6Ah电池全球首发，携手蔡司共绘质量新篇章

Core Viewpoint - Jiangsu Ruien New Energy Technology has launched a groundbreaking product, the 21700-6.0Ah earless cylindrical cell, achieving an energy density exceeding 300Wh/kg, marking a significant milestone in the battery industry [1][3][10]. Product Features - The newly released INR21700-RH60 and RS60 models utilize an industry-leading "earless design," significantly reducing internal resistance and enhancing energy density and cycle life [3][4]. - The battery design incorporates a "high nickel positive electrode + silicon-carbon composite negative electrode" system, pushing energy density above 300Wh/kg, suitable for various applications including electric tools and low-altitude aircraft [3][5]. - INR21700-RH60 supports ≥20A continuous discharge and ≥15C pulse discharge, while INR21700-RS60 supports ≥50A continuous discharge and ≥30C pulse discharge, catering to high energy and power density requirements [4]. Performance and Longevity - INR21700-RH60 maintains a capacity retention rate of ≥80% after 1000 cycles at 1C charge/2C discharge under 25°C and 100% SOC [6][8]. - INR21700-RS60 retains ≥80% capacity after 600 cycles at 2.5C charge/5C discharge under 25°C and 100% SOC [7][8]. - The batteries are designed for a wide temperature range of -40°C to 80°C, supporting charging at -20°C to 60°C and discharging at -40°C to 80°C, broadening their application scenarios [5]. Strategic Collaborations - Following the product launch, Ruien New Energy signed a strategic cooperation agreement with Carl Zeiss (Shanghai) to establish a battery quality innovation laboratory, enhancing quality control throughout the battery lifecycle [14]. - This collaboration aims to leverage Zeiss's precision testing expertise and Ruien's innovation in new energy, promoting high-quality development in the global new energy sector [14]. Future Outlook - The launch of the 21700-6.0Ah battery and the partnership with Zeiss signify Ruien's commitment to driving global energy transformation through "technology + quality" dual strategies [17]. - The company views the achievement of 300Wh/kg as a starting point for further advancements in battery technology [17].
