Core Viewpoint - The launch of the 21700-6.0Ah ultra-earless cylindrical cell by Jiangsu Ruien New Energy Technology represents a significant breakthrough in energy density, exceeding 300Wh/kg, and aims to redefine battery performance and applications in various sectors [1][4][16]. Product Features - The newly released INR21700-RH60 and RS60 models utilize an industry-leading "ultra-earless design" that significantly reduces internal resistance, enhancing energy density and cycle life [4]. - The battery features a "9-series ultra-high nickel positive electrode + silicon-carbon composite negative electrode" system, achieving energy density above 300Wh/kg, suitable for long-lasting and high-power applications [4][9]. - 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 [7][8]. Application Scope - The batteries can be widely applied in various fields, including two-wheelers, electric tools, garden tools, household appliances, portable energy storage, robotics, low-altitude aircraft, and engineering machinery [5]. Performance Metrics - INR21700-RH60 maintains a capacity retention rate of ≥80% after 1000 cycles at 1C charge/2C discharge under 25°C and 100% SOC, and 1500 cycles at 90% SOC [11]. - INR21700-RS60 retains ≥80% capacity after 600 cycles at 2.5C charge/5C discharge under 25°C and 100% SOC, and 1000 cycles at 90% SOC [12]. - The batteries are designed to operate in extreme temperatures, supporting charging from -20°C to 60°C and discharging from -40°C to 80°C, broadening their application scenarios [10]. Quality Assurance - The manufacturing process ensures high consistency, with overall CPK >1.33 and critical process CPK >1.67, guaranteeing stable performance in harsh conditions [13]. Strategic Collaboration - Following the product launch, Ruien New Energy signed a strategic cooperation agreement with Carl Zeiss (Shanghai) to establish a battery quality innovation laboratory, focusing on quality control throughout the battery lifecycle [19]. - This collaboration aims to leverage Zeiss's expertise in precision testing and Ruien's innovations in the new energy sector to enhance battery development and production [19][20]. Future Outlook - The company emphasizes that achieving 300Wh/kg is just the beginning, with aspirations to drive global energy transition through innovation and collaboration with partners [23].
