鋰離子電池用錳鐵磷酸鹽（LMFP）專利模式分析（2026）

LMFP：下一代鋰離子電池極具潛力的正極材料，專利活動快速成長且變化顯著

全球對高效能環保儲能解決方案的需求快速成長，這主要得益於電動車（EV）和大規模儲能系統（ESS）的廣泛應用，使得鋰離子電池（LIB）先進正極材料的研發成為關注的焦點。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廣受認可，但其相對較低的工作電壓（通常約為3.4 V/Li/Li+）和有限的能量密度使其無法滿足高性能應用日益增長的需求。為了因應這項挑戰，錳鐵磷酸鹽鋰（LMFP）應運而生，它以錳部分取代橄欖石結構中的鐵，成為極具潛力的替代方案。這種複合材料繼承了磷酸鐵鋰（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增加了10-20%。儘管有這些優勢，鋰金屬磷酸鐵鋰（LMFP）也面臨著自身的挑戰。這些挑戰包括電子和離子電導率低、鋰離子擴散緩慢、錳的浸出以及與Mn³⁺的Jahn-Teller效應相關的容量衰減。過去十年，這促使人們開展了廣泛的研究，並獲得了強勁的專利活動的支持。

辨識新的智慧財產權進入者

自2023年以來，中國企業已成為LMFP專利領域的主要新進者。自2023年以來，已有超過410家新的智慧財產權公司進入LMFP專利領域，其中約80%為中國公司。超過20家新進者為非中國新創企業。中國公司主要為材料和電池製造商，其他亞洲公司則主要為研發機構和材料製造商。來自美國的新進業者既包括新創企業，也包括成熟公司。其他非亞洲公司主要由研發機構、電池製造商和材料供應商組成。

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.
