锂离子电池用锰铁磷酸盐（LMFP）专利模式分析（2026）

LMFP：下一代锂离子电池极具潜力的正极材料，专利活动快速成长且变化显着

全球对高效能环保储能解决方案的需求快速成长，这主要得益于电动车（EV）和大规模储能系统（ESS）的广泛应用，使得锂离子电池（LIB）先进正极材料的研发成为关注的焦点。橄榄石结构的磷酸铁锂（LFP）因其高安全性、稳定性、低成本和环境友善性而广受认可，但其相对较低的工作电压（通常约为3.4 V/Li/Li+）和有限的能量密度使其无法满足高性能应用日益增长的需求。为了因应这项挑战，锰铁磷酸盐锂（LMFP）应运而生，它以锰部分取代橄榄石结构中的铁，成为极具潜力的替代方案。这种复合材料继承了磷酸铁锂（LFP）的高热稳定性和成本效益，同时利用锰的高氧化还原电位，使其能量密度比LFP增加了10-20%。儘管有这些优势，锂金属磷酸铁锂（LMFP）也面临着自身的挑战。这些挑战包括电子和离子电导率低、锂离子扩散缓慢、锰的浸出以及与Mn³⁺的Jahn-Teller效应相关的容量衰减。过去十年，这促使人们开展了广泛的研究，并获得了强劲的专利活动的支持。

辨识新的智慧财产权进入者

自2023年以来，中国企业已成为LMFP专利领域的主要新进者。自2023年以来，已有超过410家新的智慧财产权公司进入LMFP专利领域，其中约80%为中国公司。超过20家新进者为非中国新创企业。中国公司主要为材料和电池製造商，其他亚洲公司则主要为研发机构和材料製造商。来自美国的新进业者既包括新创企业，也包括成熟公司。其他非亚洲公司主要由研发机构、电池製造商和材料供应商组成。

LMFP: A promising cathode material for next-generation Li-ion batteries witnessing a fast-growing and shifting patenting activity

The burgeoning global demand for highly efficient and environmentally friendly energy storage solutions, driven primarily by the widespread adoption of electric vehicles (EVs) and large-scale energy storage systems (ESS), has made the development of advanced lithium-ion battery (LIB) cathode materials a critical focus. While the olivine-structured lithium iron phosphate (LFP) is widely valued for its high safety, stability, low cost, and environmental friendliness, its relatively low operating voltage, typically around 3.4 V (vs. Li/Li+), limits its energy density and falls short of the increasing requirements for high-performance applications. Lithium manganese iron phosphate (LMFP), developed by partially substituting iron with manganese in the olivine structure, has emerged as a promising alternative. This composition incorporates the high thermal stability and cost-effectiveness of LFP while leveraging the higher redox potential of manganese, resulting in a 10% to 20% higher energy density than LFP. Despite these advantages, LMFP faces intrinsic challenges notably poor electronic and ionic conductivity, sluggish lithium-ion diffusion kinetics, manganese dissolution issues, and capacity degradation related to the Jahn-Teller effect induced by Mn3+. Consequently, extensive research, supported by robust patent activity, has been performed for the last ten years.

In this context, the present report aims to provide a comprehensive analysis of the patent landscape related to the lithium manganese iron phosphate, from materials to battery cells. Knowmade's analysts have selected and analyzed more than 7,800+ patent families (inventions) related to LMFP.

The general objectives of the present report are:

• to identify and map the key IP players in each chosen technological segment (precursors, cathode active materials, cathodes, battery cells).
• to assess the geographical distribution of patent families, current legal status of patents, helping stakeholders understand strategic positioning and navigate their competitive environment.
• to get an overview of key and recent patents across the value chain.

These strategic insights will support R&D, investment, and policy decisions in the evolving field of Li-ion battery.

Understanding the main trends, the key players' IP position and IP strategy

IP competition analysis should reflect the vision of players with a strategy to enter and develop their business in the LMFP Li-ion battery market. In this report, Knowmade's analysts provide a comprehensive overview of the competitive IP landscape and latest technological developments in this field. The report identifies the IP leaders, most active patent applicants, and new entrants in the IP landscape. It also sheds light on under-the-radar companies and new players in this field. The report covers IP dynamics and key trends in terms of patents applications, patent assignees, filing countries, and technological segment of interest (precursors, cathode active materials, cathode, battery cells, etc.). Dedicated sections of the report focus on the patent portfolios of key players from various countries.

Identify the IP newcomers

Since 2023, Chinese entities have established themselves as dominant newcomers in the LMFP patent landscape. Over 410 new IP players have entered the LMFP patent landscape since 2023, with around 80% coming from China. More than 20 newcomers are non-Chinese start-ups. The main Chinese entrants are material and battery manufacturers, while other Asian newcomers are primarily R&D institutes and material producers. American newcomers include both start-ups and established companies, whereas other non-Asian entrants consist mainly of R&D organizations, battery manufacturers, and material suppliers. Dedicated sections of the report focus on the patent portfolios of IP new entrants from various countries.
