Core Viewpoint - CATL has unveiled several new products including the second-generation Shensheng fast-charging battery, second-generation sodium-ion battery, and the Xiaoyao dual-core battery architecture, which are expected to drive demand for negative electrode materials and related supply chains [2][8]. Group 1: Product Launches - The second-generation Shensheng battery features a peak charging rate of 12C, enabling a 75 km range in just 30 seconds and 520 km in 5 minutes, making it the world's first lithium iron phosphate fast-charging battery with such specifications [3]. - The second-generation sodium battery, branded as "Sodium New," maintains over 90% energy efficiency at -40°C, with an energy density of 175 Wh/kg, and is set for mass production in June 2025 [4]. - The Xiaoyao dual-core battery utilizes a self-generating negative electrode technology, which enhances energy density by 60% in volume and 50% in mass, while being compatible with various battery systems [5][6]. Group 2: Material Impact - The negative electrode materials, particularly graphite and coating materials, are expected to benefit from the deployment of fast-charging products [3]. - The hard carbon segment is anticipated to see increased demand as the sodium battery production approaches [4]. - The self-generating negative electrode technology is projected to have a limited impact on existing negative electrode systems, such as graphite [5][6].
