Core Viewpoint - The lithium battery industry is experiencing a structural transformation characterized by the simultaneous expansion of high-end production and the contraction of low-end capacity, leading to a competitive elimination phase within the industry [3][4][6]. Group 1: Industry Dynamics - As of September, over 20 projects in the lithium battery supply chain have been terminated, suspended, or delayed, with a total investment exceeding 110 billion yuan [2]. - In the first eight months of 2025, 183 new projects were signed or commenced in China's lithium battery industry, with a total investment of approximately 400 billion yuan, focusing on high-end technologies such as high-voltage lithium iron phosphate and high-nickel ternary materials [3]. - The industry is witnessing an accelerated elimination of low-end capacity, particularly in areas with high homogeneity like precursor materials and lithium iron phosphate, due to intensified competition and rising barriers in cost control and environmental regulations [4]. Group 2: Demand and Growth - Demand for energy storage and power batteries remains strong, with energy storage systems accounting for 27% of global battery shipments and over 40% in the lithium iron phosphate segment [6]. - The average battery capacity of pure electric vehicles has increased by 16.4% year-on-year, indicating a release of demand elasticity [6]. - Companies with scale delivery and cost advantages are securing full orders, while those lacking competitiveness may face idle capacity despite being in a high-demand sector [6]. Group 3: Technological Advancements - The focus of capital and capacity expansion is shifting towards high-end technologies such as high-voltage lithium iron phosphate, high-nickel ternary, and solid-state batteries, while investment in low-end routes is declining [7]. - The industry is moving away from merely pursuing scale towards establishing technological barriers and product upgrades to avoid price wars [7]. - However, the termination of solid-state battery projects indicates the high barriers and long cycles associated with these technologies, emphasizing the need to address substantial industrialization challenges [8]. Group 4: International Expansion Risks - There is an increasing risk associated with overseas expansion, with projects in Indonesia, the United States, and South Korea frequently being halted, often involving investments of tens of billions to hundreds of billions of dollars [10]. - Uncertainties related to tariffs, subsidy policies, and localization requirements are significantly narrowing the investment return rates for overseas factories [10]. - The year 2025 is seen as a turning point for international expansion, with geopolitical risks becoming a core consideration in investment decisions [10].
