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.
