LMFP：一种有前景的下一代锂离子电池正极材料，专利申请趋势正在迅速扩展和变化。

在电动车（EV）和大规模能源储存系统（ESS）普及的推动下，全球对高效环保储能解决方案的需求激增，使得锂离子电池（LIB）先进正极材料的研发成为关键。具有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备受青睐。然而，其相对较低的工作电压（通常在3.4 V (Li/Li+) 左右）限制了其能量密度，使其无法满足高性能应用日益增长的需求。透过在橄榄石结构中以锰取代部分铁而开发的锰铁磷酸锂（LMFP）正成为极具前景的替代方案。这种材料继承了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高出10%至20%。儘管锂金属燃料电池（LMFP）具有这些优势，但它们也存在一些固有的挑战，包括电子和离子电导率低、锂离子扩散速率慢、锰溶解问题以及与Mn³⁺诱导的姜-柜员效应相关的容量劣化。因此，在过去十年中，人们进行了​​大量研究，并积极申请专利。

在此背景下，本报告旨在对与锂锰铁磷酸盐（LMFP）相关的专利趋势进行全面分析，涵盖从材料到电池的各个方面。 Knowmade分析师筛选并分析了7,800多项与LMFP相关的专利系列（发明）。

本报告的主要目标如下：

• 识别并绘製参与企业。
• 评估专利系列的地理分布和当前的专利法律环境，帮助相关人员了解其策略定位并掌握竞争格局。
• 了解整个价值链中的关键和最新专利概况。

这些策略见解将为不断发展的锂离子电池领域的研究与开发、投资和政策制定提供支援。

了解主要趋势、主要参与企业的智慧财产权状况及其智慧财产权策略。

智慧财产权（IP）竞争分析应反映每家公司进入LMFP锂离子电池市场并制定企业发展策略的愿景。在本报告中，Knowmade分析师全面概述了该领域的竞争格局和最新技术趋势。报告重点介绍了智慧财产权领域的领导企业、最活跃的专利申请人和新参与企业，同时也关注了该领域中知名度较低的企业和新参与企业。报告涵盖了专利申请、专利持有人、申请国家以及重要技术领域（前驱物、正极活性材料、正极、电池单元等）的智慧财产权趋势和关键发展动态。报告也特别设立章节，重点介绍各国主要企业的专利组合。

识别知识产权领域的新进入者

自2023年以来，中国企业已成为LMFP专利领域的主导新晋力量。自2023年以来，已有超过410家新的智慧财产权参与企业进入LMFP专利领域，其中约80%来自中国。超过20家新晋企业是来自中国以外的Start-Ups。中国参与企业主要为材料製造商和电池製造商，而其他亚洲新晋企业则主要为研发机构和材料製造商。美国新晋企业既包括Start-Ups公司也包括成熟企业，而其他非亚洲新晋企业则主要由研发机构、电池製造商和材料供应商组成。本报告的专门章节将重点介绍各国新进入该领域的智慧财产权企业的专利组合。

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.

Deep dive into key and recent patents across LMFP value chain

All patents selected for this study have been categorized by supply chain segment (precursor, cathode material, cathode, battery cells).

For each supply chain segment, this report includes a time-evolution of patent applications, main and key patent assignees, and a description of key and recently patented technologies. An understanding of the current technical challenges addressed in the patents is also presented.

Useful Excel patent database

This report also includes an extensive Excel database with all patents analyzed in this study, including patent information (numbers, dates, assignees, title, abstract, etc.), hyperlinks to an updated online database (original documents, legal status, etc.), and supply chain segments (precursors, cathode active materials, cathodes, battery cells).

Interactive dashboard (optional)

Optional add-on: One-year access to the interactive dashboard for unlimited authorized users within your organization.

An interactive dashboard can be provided with this report, transforming the analysis into a true decision-support tool that puts you in control. It enables you to explore the patent landscape dynamically by applicant, technology, geography, publication period, or legal status, and to drill down instantly into key insights, from high-level trends to individual players and patents.

Tailored to the specific needs of R&D, IP, strategy, and business development teams, the dashboard delivers immediate visual answers to critical questions, enabling faster and more informed strategic decision-making across your organization.
