Core Viewpoint - The article highlights the growing demand for high-density lithium iron phosphate (LFP) batteries, driven by advancements in energy storage and electric vehicle technologies, and discusses the investment plans of Fujilin Precision Engineering in this sector [2][3][4]. Investment and Production Plans - Fujilin Precision Engineering's subsidiary, Jiangxi Shenghua, plans to invest in a new project in Deyang-Abazhou Ecological Economic Industrial Park, aiming for an annual production capacity of 350,000 tons of new high-pressure dense LFP [2][3]. - The project will be constructed in two phases, with the first phase targeting an annual output of 175,000 tons and the second phase also aiming for 175,000 tons [2]. Market Demand - There is a significant market demand for high-pressure dense LFP materials, with a reported monthly shipment exceeding 40,000 tons in the first half of 2025 [3]. - The demand is driven by the need for larger capacity, higher energy density, and fast-charging capabilities in energy storage and power batteries [4]. Technological Advancements - The industry is witnessing a shift towards fast-charging batteries, with many manufacturers announcing 800V high-voltage platform fast-charging models [5]. - Leading companies like CATL are expected to achieve mass production of 587Ah batteries next year, indicating a trend towards higher capacity batteries [6]. Production Techniques - The mainstream production methods for high-pressure dense LFP include the phosphoric acid method and the oxalic acid iron method, with the latter being favored for its efficiency and lower energy consumption [7][8]. - The oxalic acid iron method requires only one sintering process, making it more efficient, although it comes with higher costs [8]. Competitive Landscape - Major companies are rapidly expanding their production capacities for high-pressure dense LFP, with a critical period expected in the fourth quarter of this year and the first half of next year [9]. - Companies such as Fujilin Precision Engineering, Hunan Youneng, Longpan Technology, Defang Nano, and Bangpu are all accelerating their capacity expansion efforts [9].
