硫磺冲上4000元，磷酸铁锂又迎成本压力？

Core Viewpoint - The recent surge in sulfur prices, which have increased by over 300% since mid-2024, is expected to raise the costs of lithium iron phosphate (LFP) and other related materials, potentially impacting the overall cost structure of the lithium battery industry [2][3]. Group 1: Sulfur Price Dynamics - Domestic solid sulfur prices have risen from approximately 915 yuan/ton to around 4100 yuan/ton, with some forecasts predicting prices could reach 6000 yuan/ton [3]. - The price increase is driven by a supply-demand imbalance, with rising contract prices in the Middle East and decreasing domestic port inventories, alongside growing demand from downstream sectors such as phosphate fertilizers and lithium batteries [3][4]. Group 2: Cost Implications for Phosphate Fertilizers - For phosphate fertilizers, a 100 yuan increase in sulfur prices leads to an approximate 50 yuan increase in production costs [6]. - Current estimates suggest that the cost of producing monoammonium phosphate has exceeded 4200 yuan/ton, while the selling price is around 3650 yuan/ton, indicating a loss of nearly 600 yuan per ton [6]. Group 3: Impact on Lithium Iron Phosphate Production - The production of one ton of lithium iron phosphate requires about 0.23 tons of sulfur, translating to a cost increase from approximately 210 yuan to 940 yuan per ton of LFP as sulfur prices rise [10]. - The overall cost structure of LFP shows that raw materials account for over 80% of total costs, with lithium sources and iron phosphate being significant components [11]. Group 4: Market Reactions and Future Considerations - The increase in sulfur costs is seen as a pressure point for LFP producers, who are already facing thin margins due to prolonged price declines and industry losses [16][17]. - The market is currently witnessing a rebound in processing fees for LFP, but the fundamental issues of profitability remain unresolved [16]. - The industry must focus on managing costs and pricing strategies, particularly in light of potential further increases in sulfur prices and their implications for overall production costs [24].
