Li-ion Battery Cathode Active Material Recycling Patent Landscape Analysis 2025

Who are the Key Players and Newcomers in the Global IP Race For Li-Ion Batteries Cathode Active Materials Recycling?

The growing interest in, and need for, a sustainable supply chain has driven innovators into an IP race in Li-ion battery CAM recycling.

The rapid adoption of electric vehicles (EVs), renewable energy storage systems, and portable electronics has fueled an exponential increase in the demand for Lithium-ion batteries. The interest in critical raw materials such as lithium, cobalt, nickel, and manganese, increased, to instate a more sustainable supply chain and increase the independence of materials-scarce countries from critical minerals suppliers. This concentration of supply, coupled with environmental concerns and evolving regulatory frameworks, has intensified the need for sustainable end-of-life management strategies, particularly the recycling of spent Li-ion batteries and their cathode materials.

Cathode materials represent the most valuable and resource-intensive components of Li-ion batteries. These include layered oxides like NMC (LiNiMnCoO₂), NCA (LiNiCoAlO₂), and LCO (LiCoO₂); polyanion materials such as LFP (LiFePO₄) and LMFP (LiMnFePO₄); and spinels like LMO (LiMn₂O₄). Each chemistry presents unique challenges and opportunities for recovery and reuse. Efficient recycling not only reduces reliance on virgin mining but also lowers the environmental footprint of battery production, contributing to the circular economy goals set by governments and industries.

In this context, the present report aims to provide a comprehensive analysis of the patent landscape related to the recycling of cathode active materials (CAM) from Li-ion batteries. 

The General Objectives of the Present Report are:

• To identify and map the key IP players in each chosen technological segment (Li & Li precursors, Li ternary oxides, Li phosphates, other cathode materials).
• To assess the geographical distribution of patent families, the legal status of patent applications, and help stakeholders understand strategic positioning and navigate their competitive environment.
• This insight will support R&D, investment, and policy decisions in the evolving field of Li-ion battery recycling.

A Dynamic IP Landscape

In this report, the analysts have selected and analyzed over 6,100 patents and patent applications from more than 3,900 patent families (inventions) related to Li-ion battery cathode active materials recycling. This significant rise clearly demonstrates a strong interest in the technology from various entities, including large companies, start-ups, and R&D labs. Early entrants in this space, such as Umicore, Eneos, and Sumitomo Metal Mini, were followed over the years by other patent applicants (e.g., LG Chem/LGES, GEM, Brunp Recycling Technology), and they are now competing with more recent new entrants in the patent landscape, such as Asaka Riken, EcoPro, and Blue Solutions.

Revealing Main Trends and Key Players’ IP Position

IP competition analysis should reflect the vision of players with a strategy to enter and develop their business in the Li-ion battery CAM recycling field. In this report, the analysts provide a comprehensive overview of the competitive IP landscape and the main players involved. The report covers IP dynamics and key trends in terms of patent applications, patent assignees, filing countries, and technological segments of interest (Li & Li precursors, Li ternary oxides, Li phosphates, etc.). It also identifies the IP leaders, most active patent applicants, and new entrants in the IP landscape. The report also sheds light on under-the-radar companies and new players in this field.

Entry of New Patent Applicants

Since 2023, Chinese entities have established themselves as dominant newcomers in the Li-ion battery CAM recycling patent landscape. BJR, CP Lighting, and Chengtun Mining Group are leading the field, while other East Asian IP players such as Orta Materials and Korea Zinc from South Korea, and JFE and Kawasaki Heavy Industries from Japan are following closely behind. Dedicated sections of the report focus on the patent portfolios of key players and IP new entrants from various countries.

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.) and hyperlinks to an updated online database (original documents, legal status, etc.), and affiliation segments (Li & Li precursors, Li ternary oxides, Li phosphates, other cathode materials).
