12月2日，一份调价通知书在锂电行业引发关注。调价通知书显示，某隔膜行业一梯队企业宣布对其湿法隔膜产品售价进行调整，上调幅度达 30%。 上海证券报记者从接近该企业的人士处获悉，确有向部分客户发出调价通知书。鑫椤锂电分析师陈雷雨对上海证券报记者表示，预计本轮锂电隔 膜整体涨价幅度可达20%以上，有望带动隔膜企业业绩由亏损或盈亏打平转为盈利。 多家隔膜企业筹划涨价 上海证券报记者从接近该企业的人士处获悉，确有向部分客户发出调价通知书。 另有从业者对上海证券报记者表示，目前其所在的公司产能利用率饱满，已对部分客户的隔膜订单价格进行上调，未来价格的走向还需视供求关 系来确定。 高工锂电方面2日称，一周前已有隔膜企业发函对湿法隔膜（基膜及涂覆隔膜）产品上调价格。而2日消息更为明确显示，多家头部隔膜企业已确 定上调隔膜产品价格。 鑫椤锂电方面分析，8月末湿法隔膜行业的反内卷会议促成了第一轮涨价行情。本次调价通知书引发湿法隔膜厂商同步跟进涨价，引发第二轮涨价 行情。目前第二轮涨价仍然在持续落地中。陈雷雨预计，本轮锂电隔膜整体涨价幅度可达20%以上。 就涨价动力，陈雷雨认为，下游需求的超预期表现，以及供需结构的改善甚至进一 ...

Summary of Conference Call on Lithium Battery Separator Industry Industry Overview - The separator industry is expected to enter a new round of price increases, with existing price hikes already affecting customers and a second round anticipated soon. New prices are effective immediately [1][2] - The lithium battery sector's inventory cycle is projected to bottom out in Q1 2024, indicating a recovery phase. If inventory trends upward, it will signal a proactive restocking phase, marking the beginning of a prosperous period for the lithium battery industry [1][4] Key Points on Price Trends - Separator products have experienced a rapid price increase of approximately 10% since August, ending a three-year deflationary cycle. This price reversal follows four major rounds of price declines due to increased competition and raw material price drops [1][5] - The separator segment is expected to face shortages starting in the second half of 2026, with price increases potentially continuing until 2027 due to long expansion cycles and limited new capacity [2][8] Supply and Demand Dynamics - The separator industry is currently in a passive destocking phase, with revenue growth occurring alongside declining inventory levels. This trend is expected to continue into 2025 [4][20] - The demand for wet-process separators is growing at 30%, driven by energy storage needs, while dry-process separator growth has slowed to 18% [1][7] Production Capacity and Market Concentration - Major suppliers like Enjie and Xingyuan are expanding conservatively, with new capacity expected to be available no earlier than 2027. This cautious approach is a significant factor in the sustainability of current price increases [1][8] - The market concentration has increased, with the top three companies holding 60% of the market share, indicating a slight recovery in their competitive positions [6][10] Technological Developments - The 5-micron wet-process separator is gaining attention for its higher energy density and safety, with prices approximately 30% higher than standard products. Its adoption is expected to rise significantly, with major clients like CATL increasing their usage [1][14] Challenges and Opportunities - The separator industry faces low profitability levels despite significant growth in shipment volumes. The operational rate is expected to reach 80% next year, enhancing the likelihood of price increases during peak seasons [20] - The industry is undergoing consolidation, with companies like Foshan Technology acquiring smaller firms to strengthen their market position [11] Future Profit Expectations - Companies like Enjie and New Source Material are projected to see significant profit increases if prices rise by an additional 0.05 to 0.1 yuan per square meter in the coming years, indicating strong growth potential as they navigate the current price increase cycle [17][19] Conclusion - The separator industry is at a pivotal moment, with potential price increases, a recovering inventory cycle, and significant technological advancements. However, challenges such as low profitability and cautious expansion plans remain critical factors to monitor in the coming years [20][21][22]
