专家解读新能源电池路线：三元锂与磷酸铁锂需并行发展

Core Viewpoint - The current solid-state battery technology lacks a clear mass production timeline, while the electric vehicle market continues to rely on ternary lithium and lithium iron phosphate batteries. Various domestic automakers and listed companies plan to increase the production of ternary lithium battery models next year to meet consumer demand for long range and high performance [1] Group 1: Technical Characteristics and Market Demand - Ternary lithium and lithium iron phosphate batteries are not mutually exclusive but are chosen based on different technical characteristics and market needs [2] - Ternary lithium batteries have a volumetric energy density exceeding 600 Wh/L, while lithium iron phosphate batteries are below 450 Wh/L, making ternary lithium more suitable for long-range applications [2] - Lithium iron phosphate batteries are considered safer due to better thermal stability, but incidents have occurred with both battery types, indicating that safety cannot be judged solely on battery type [2][3] Group 2: Policy and Industry Development - National policies have consistently encouraged the diversification of battery technology routes, with subsidies favoring high energy density batteries since 2017 [4] - The Chinese ternary lithium battery industry is the largest globally, with leading companies at the forefront of technology, emphasizing the need for continued advancement in ternary lithium technology [4] Group 3: Industry Competition and Collaboration - The current low-price competition in the battery industry has negatively impacted the sustainable development of the industry, necessitating collaboration among stakeholders to establish technical standards and avoid detrimental practices [5] - Experts advocate for a dual approach, leveraging the advantages of both battery types while focusing on technological innovation to enhance product performance and safety [5]
