Core Viewpoint - The article discusses the emerging trend of lithium battery technology, particularly focusing on manganese iron phosphate (LMFP) as an upgraded version of lithium iron phosphate (LFP), highlighting its advantages, challenges, and industrial application progress [2][5][6]. Summary by Sections Advantages of LMFP - LMFP offers a combination of high energy density and safety, with a theoretical mass energy density of 697 Wh/kg, which is 20% higher than LFP [6][8]. - It has a higher voltage platform of 4.1V compared to LFP's 3.4V, and better low-temperature performance, maintaining 77-80% capacity at -20°C, compared to LFP's 45-60% [8]. - The cost structure is favorable, with raw material costs for LMFP at approximately 73.7%, and it is cheaper than NCM622 and NCM811 by 7,000-8,000 yuan per ton [8]. Challenges Facing LMFP - Technical barriers exist, such as the uniformity of manganese and iron distribution, which affects performance due to multiple side reactions [9]. - LMFP has low electrical conductivity and slow lithium ion diffusion rates, making it less efficient compared to LFP [9]. - The Jahn-Teller effect from manganese can lead to structural distortion, and the presence of an abnormal lithium intercalation platform can reduce energy density and consistency across batches [10]. Technological Solutions by Times Rhyme - The company has developed two main solutions to address the challenges of LMFP: 1. "1+1" Core Technology: This includes co-precipitation precursor technology for precise control of manganese and iron ratios, and nanocrystal design to enhance lithium ion migration [23][24]. 2. "3+2" Technology Matrix: This involves multi-ion doping to suppress the Jahn-Teller effect, lithium fast ion conductor layers for high-rate charging, and surface modification techniques to improve efficiency [25][26]. Industrialization and Production Capacity - Times Rhyme has established a production capacity of 20,000 tons per year, with the first phase of LMFP production starting in April 2025 [30][32]. - The company is positioned to meet the demand across various applications, including electric vehicles and consumer electronics, with a focus on enhancing safety and performance [31][32]. Market Position and Future Outlook - With advancements in technology and production capabilities, Times Rhyme is expected to rapidly increase its market share as the application of LMFP accelerates [32].
