宁德时代，否认固态电池传闻

Core Viewpoint - CATL (Contemporary Amperex Technology Co., Limited) has denied rumors about mass production of solid-state batteries with a range of 2000 km and energy density of 450 Wh/kg by 2027, stating that commercialization will take more time and is expected to achieve small-scale trial production by 2027 and large-scale production around 2030 [1][2]. Group 1: Solid-State Battery Development - CATL continues to invest in solid-state battery research to maintain its technological advantage, but acknowledges that significant engineering breakthroughs are needed for mass production [1]. - Industry experts agree that while the theoretical feasibility of solid-state batteries has been validated, challenges in material processes, cost control, and production consistency remain [1]. Group 2: Other Battery Technologies - Despite the lack of solid-state battery production, CATL is actively launching new products in other battery technology areas, including the 8-series high-nickel battery, which has a nickel content of about 80% [2]. - The 8-series battery was widely used in various models from automakers like GAC Aion, NIO, and Xpeng, but faced issues with thermal management leading to safety concerns [2]. - CATL emphasizes that abandoning the 8-series would mean giving up on the high-end market, indicating a commitment to ongoing research and development [2]. Group 3: Recent Product Launches - In November 2024, CATL introduced the Tectrans battery system designed for heavy trucks, featuring a single cell capacity of 1000 kWh [3]. - By September 2025, CATL announced that its sodium-ion battery, Naxtra, was ready for mass production, with an energy density of approximately 175 Wh/kg and a range of up to 500 km, set for production in 2026 [3]. - CATL also launched the NP3.0 technology platform, achieving the highest safety level in the battery field, and introduced the Shenhxing Pro lithium iron phosphate battery [3]. - Plans for a new 8-series high-nickel ternary battery to be launched in 2026 were also announced, aiming to regain technological and market advantages in the ternary battery sector [3].
