【基础化工】储能需求强劲，磷酸铁景气改善——基础化工行业周报（20251103-20251107）（赵乃迪/周家诺/胡星月）

Core Viewpoint - The rapid growth of new energy storage installations is driving continuous demand for the lithium iron phosphate (LFP) industry chain, with significant increases in production and investment expected in the coming years [4][5]. Group 1: New Energy Storage Growth - From 2021 to 2024, domestic new energy storage installations are projected to grow from 2.4 GW to 43.8 GW, with a CAGR of approximately 162% [4]. - In the first half of 2025, domestic new energy storage installations reached 23.03 GW, a year-on-year increase of 68%, with May 2025 seeing a record monthly addition of 10.25 GW [4]. - The National Development and Reform Commission and the National Energy Administration expect over 100 million kW of new energy storage capacity to be added nationwide by 2027, driving direct project investments of around 250 billion yuan [4]. Group 2: Supply and Demand Dynamics - The supply-demand balance for lithium iron phosphate is improving, with the industry operating rate reaching 81.6% as of November 7, 2025, an increase of 30.1 percentage points year-on-year [5]. - Domestic lithium iron phosphate inventory has decreased to approximately 24,500 tons as of November 7, 2025, down about 22.1% from the end of June 2025, indicating tightening supply [5]. Group 3: Price and Profitability Trends - Domestic lithium iron phosphate prices have started to stabilize and recover, reaching 10,500 yuan per ton as of November 7, 2025, a rise of about 0.6% since the end of August [6]. - Although the average gross profit margin in the industry remains negative, companies with complete industrial chain layouts, such as Chengheng Co., have shown significant improvement in profitability, with net profit margins improving from -30.7% in 2024 to -7.4% in the first half of 2025 [6]. Group 4: Phosphate Rock Supply and Pricing - Since 2021, domestic phosphate rock prices have been on the rise, maintaining above 1,000 yuan per ton since the end of 2023, with the average selling price for 30% grade phosphate rock at approximately 1,017 yuan per ton as of November 7 [8]. - The high pricing of phosphate rock is attributed to a tight supply of high-grade phosphate rock, limited market circulation, and rising mining costs due to environmental regulations [8]. - The effective production capacity of phosphate rock in China is expected to reach about 122 million tons per year by 2025, with only a modest increase of 2.5 million tons from 2024, indicating limited short-term capacity growth [8].
