电新-锂电隔膜专家交流

Summary of Conference Call Notes Industry Overview - The conference call primarily discusses the lithium battery separator industry, focusing on pricing trends, supply chain dynamics, and key suppliers in the market [1][3][10]. Key Points and Arguments Pricing Trends - Starting January 2026, the price of 7μm base film is expected to increase to 0.9 CNY per square meter, representing a nearly 20% increase. However, market acceptance and the overall profitability of the separator industry will impact price stability [1]. - The current market price for lithium battery separators is 0.75 CNY as of December 2025, showing no change compared to July and August [3]. - The separator industry has been struggling with profitability, necessitating price increases to maintain supply [3]. Supply Chain and Procurement - The company procures 270 million square meters of separators monthly, with 70 million square meters being 5μm and 200 million square meters being 7μm, maintaining a ratio of approximately 2:3 [1][5]. - Key suppliers include Jinli and Lanketu, with Jinli being prioritized due to higher profit margins, while Lanketu is bound by strategic partnerships despite underperforming in capacity expansion [1][8]. - The expected demand for separators in 2026 is between 450 million to 500 million square meters, with plans to introduce new suppliers and increase Jinli's share to meet this demand [10]. Supplier Performance and Challenges - Jinli's current monthly output is 600 million square meters, with 300 million square meters supplied to the company [11]. - Lanketu's total capacity is 50 million square meters, with plans to expand to 100 million square meters, but actual output has only reached 20 million square meters due to quality issues [9]. - Enjie has not passed the verification for its 5μm products, which may lead to limited procurement in 2027 due to strategic considerations and existing conflicts with suppliers [12][13]. Industry Risks and Future Outlook - The separator industry faces certain risks, but large-scale bankruptcies are unlikely. Companies are cautious about expansion due to the potential decrease in demand for traditional separators with the advancement of solid-state battery technology [20]. - The industry is expected to stabilize in the short term, but long-term impacts from technological changes need to be monitored [20]. Additional Insights - The processing fee for coating films is approximately 0.5 CNY per square meter, with a profit margin of about 20% [16]. - The main suppliers in the separator market include Anji, Enjie, Zhongcai, and Housheng, with a significant portion of supply concentrated among a few large manufacturers to ensure stable supply [17]. - The development of sodium-ion batteries is hindered by low energy density and high costs, making them less competitive compared to lithium-ion technologies [23]. Conclusion - The lithium battery separator industry is experiencing price increases and supply chain adjustments in response to market dynamics. Key suppliers are being closely monitored for performance and strategic alignment, while the industry remains cautious about future technological shifts and their potential impacts on demand.
