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 [2][3]. Group 1: Solid-State Battery Development - CATL acknowledges the theoretical feasibility of solid-state batteries but emphasizes the need for breakthroughs in materials, cost control, and production consistency before mass production can occur [4]. - The company plans to achieve small-scale trial production of solid-state batteries by 2027 and aims for large-scale production and commercial application around 2030 [3]. Group 2: Other Battery Innovations - Despite the delay in solid-state battery production, CATL continues to innovate in other battery technologies, including the Tectrans battery system designed for heavy-duty trucks, with a single cell capacity of 1000 kWh, set to launch in November 2024 [5]. - In September 2025, CATL announced that its sodium-ion battery, Naxtra, has reached readiness for mass production, with an energy density of approximately 175 Wh/kg and a range of up to 500 km, expected to be produced in 2026 [5]. - CATL introduced the NP3.0 technology platform, the highest safety level in the battery field, along with the release of the Shenhung Pro lithium iron phosphate battery product in September 2025 [6]. Group 3: High-Nickel Battery Strategy - CATL plans to launch a new 8-series high-nickel ternary battery in 2026, aiming to regain technological and market advantages in the ternary battery sector [7]. - The 8-series high-nickel battery, which contains approximately 80% nickel, was previously a star product but faced challenges due to safety concerns. CATL emphasizes the importance of this technology for high-end markets [7]. Group 4: Multi-Route Innovation Strategy - CATL's innovation strategy is not solely focused on solid-state batteries but involves parallel advancements in high energy density lithium-ion systems, sodium-ion alternatives, and various electrochemical systems tailored for different applications, including passenger vehicles, commercial vehicles, and aviation [8].
