Core Viewpoint - The maturity of sodium-ion batteries is significant as it will accelerate the arrival of a multi-core system in the battery industry, allowing for customizable battery solutions that prioritize user needs over mere specifications [2][6]. Group 1: Product Launch and Features - On April 21, CATL launched three major products at its first Tech Day, including the sodium-ion battery, the Xiaoyao dual-core battery, and the second-generation Shenxing ultra-fast charging battery [2]. - The sodium-ion battery is the world's first mass-produced automotive-grade sodium battery, capable of achieving "saw-cut non-flammability," peak 5C fast charging, and maintaining 90% energy retention at -40°C [2][3]. - The sodium-ion battery will officially enter mass production by December 2025, with the first application in a chocolate battery swap model [2][4]. Group 2: Market Position and Strategic Importance - Sodium is abundant and cost-effective, providing a strategic energy solution that is less susceptible to geopolitical risks compared to lithium, which is concentrated in limited regions [3]. - The sodium-ion battery can significantly reduce carbon emissions throughout its lifecycle, with carbon emissions from sodium battery cells being 30% to 60% lower than those from lithium battery cells [3]. Group 3: Performance and Applications - The sodium-ion battery features an energy density of 175Wh/kg, enabling over 500 kilometers of pure electric range and over 200 kilometers of hybrid range, with a cycle life exceeding 10,000 times [3][4]. - The high-voltage sodium battery addresses the needs of private cars and commercial vehicles in northern regions, ensuring performance even in extreme cold [4]. Group 4: Future Outlook and Industry Impact - The sodium-ion battery has the potential to replace half of the market share currently held by lithium iron phosphate batteries in the medium to long term [5]. - The integration of sodium batteries with lithium-ion technologies will solidify the foundation of the new energy industry and promote global electrification [5][6]. - The multi-core technology will enable battery customization, allowing consumers to meet their specific needs without compromise, thus shifting the industry focus from price competition to value creation [7].
