高压实铁锂需求激增，草酸亚铁法抢跑

Core Viewpoint - The article highlights the rapid growth and demand for high-density lithium iron phosphate (LFP) batteries, particularly driven by advancements in fast-charging technology and the limited number of companies capable of producing high-density LFP using the oxalic acid iron preparation method [1][5]. Industry Overview - In Q1 2025, China's lithium battery shipments reached 314 GWh, a year-on-year increase of 55%, with lithium iron phosphate cathode material shipments at 760,000 tons, accounting for 76% of total cathode material shipments and achieving a year-on-year growth of 94% [2]. - High-density LFP products are leading the market in terms of orders and profit margins, primarily used in fast-charging power batteries and large energy storage cells [3][4]. Technological Advancements - The oxalic acid iron preparation method is gaining traction, with only 2-3 companies mastering this technology, which is utilized by CATL in its Shenxing battery [5][6]. - The oxalic acid method allows for a single sintering process, resulting in higher purity and better performance compared to the traditional iron phosphate method, which requires multiple sintering and incurs higher energy costs [6][7]. Company Developments - Pengbo New Materials has initiated a new lithium iron phosphate project in Shanxi, with an annual production capacity of 200,000 tons planned to commence trial production in September 2025 [5]. - The company has developed various high-density LFP products, achieving stable mass production and technological leadership in the field [9][10]. Market Positioning - Pengbo New Materials is positioned strongly in the high-density LFP market, with its products already being used in high-end electric vehicles and commercial energy storage applications [12]. - The company has established production bases in Ningxiang and Yangquan, with a total planned capacity of 100,000 tons per year to meet the growing demand for LFP materials [12]. Upcoming Events - Pengbo New Materials will showcase its products at the CIBF 2025 from May 15-17, 2025, in Shenzhen, highlighting its advancements in LFP and manganese iron lithium materials [11][13].
