LMFP：一種有前景的下一代鋰離子電池正極材料，專利申請趨勢正在迅速擴展和變化。

在電動車（EV）和大規模能源儲存系統（ESS）普及的推動下，全球對高效環保儲能解決方案的需求激增，使得鋰離子電池（LIB）先進正極材料的研發成為關鍵。具有橄欖石結構的磷酸鐵鋰（LFP）因其高安全性、穩定性、低成本和環境友善性而備受青睞。然而，其相對較低的工作電壓（通常在3.4 V (Li/Li+) 左右）限制了其能量密度，使其無法滿足高性能應用日益成長的需求。透過在橄欖石結構中以錳取代部分鐵而開發的錳鐵磷酸鋰（LMFP）正成為極具前景的替代方案。這種材料繼承了LFP的高熱穩定性和成本效益，同時利用錳的高氧化還原電位，使其能量密度比LFP高出10%至20%。儘管鋰金屬燃料電池（LMFP）具有這些優勢，但它們也存在一些固有的挑戰，包括電子和離子電導率低、鋰離子擴散速率慢、錳溶解問題以及與Mn³⁺誘導的薑-櫃員效應相關的容量劣化。因此，在過去十年中，人們進行了​​大量研究，並積極申請專利。

在此背景下，本報告旨在對與鋰錳鐵磷酸鹽（LMFP）相關的專利趨勢進行全面分析，涵蓋從材料到電池的各個方面。 Knowmade分析師篩選並分析了7,800多項與LMFP相關的專利系列（發明）。

本報告的主要目標如下：

• 識別並繪製參與企業。
• 評估專利系列的地理分佈和當前的專利法律環境，幫助相關人員了解其策略定位並掌握競爭格局。
• 了解整個價值鏈中的關鍵和最新專利概況。

這些策略見解將為不斷發展的鋰離子電池領域的研究與開發、投資和政策制定提供支援。

了解主要趨勢、主要參與企業的智慧財產權狀況及其智慧財產權策略。

智慧財產權（IP）競爭分析應反映每家公司進入LMFP鋰離子電池市場並制定企業發展策略的願景。在本報告中，Knowmade分析師全面概述了該領域的競爭格局和最新技術趨勢。報告重點介紹了智慧財產權領域的領導企業、最活躍的專利申請人和新參與企業，同時也關注了該領域中知名度較低的企業和新參與企業。報告涵蓋了專利申請、專利持有人、申請國家以及重要技術領域（前驅物、正極活性材料、正極、電池單元等）的智慧財產權趨勢和關鍵發展動態。報告也特別設立章節，重點介紹各國主要企業的專利組合。

識別知識產權領域的新進入者

自2023年以來，中國企業已成為LMFP專利領域的主導新晉力量。自2023年以來，已有超過410家新的智慧財產權參與企業進入LMFP專利領域，其中約80%來自中國。超過20家新晉企業是來自中國以外的Start-Ups。中國參與企業主要為材料製造商和電池製造商，而其他亞洲新晉企業則主要為研發機構和材料製造商。美國新晉企業既包括Start-Ups公司也包括成熟企業，而其他非亞洲新晉企業則主要由研發機構、電池製造商和材料供應商組成。本報告的專門章節將重點介紹各國新進入該領域的智慧財產權企業的專利組合。

對LMFP價值鏈中的關鍵專利和最新專利進行詳細分析

本研究中選取的所有專利均依供應鏈環節（前驅體、陰極材料、陰極和電池單元）進行分類。

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.
