对永续供应链日益增长的兴趣和需求，正在推动创新者加入锂离子电池正极活性材料回收的专利竞争电池。

随着电动车 (EV)、再生能源储存系统和便携式电子产品的迅速普及，锂离子电池的需求呈指数级增长。为了建立更永续的供应链，并增强对材料匮乏国家关键矿产供应商的独立性，人们对锂、钴、镍和锰等关键原料的兴趣日益浓厚。这种供应集中，加上环境问题和不断变化的监管框架，正在推动对永续报废管理策略的需求，特别是报废锂离子电池及其正极材料的回收利用。

正极材料是锂离子电池中最有价值且资源密集的组成部分。这些材料包括层状氧化物，如 NMC（LiNiMnCoO2）、NCA（LiNiCoAlO2）和 LCO（LiCoO2），多阴离子材料，如 LFP（LiFePO4）和 LMFP（LiMnFePO4），以及尖晶石，如 LMO（LiMn2O4）。每种化学品的回收和再利用都面临独特的课题和机会。高效率的回收不仅可以减少对原始采矿的依赖，还可以降低电池製造的环境足迹，并有助于实现政府和产业设定的循环经济目标。

为此，本报告旨在全面分析与锂离子电池正极活性材料 (CAM) 回收相关的专利模式。

Who are the key players and newcomers in the global IP race for Li-ion batteries cathode active materials recycling?

Key features:

• PDF>120 slides
• Excel database containing all patents analyzed in the report (>3,900 patent families), including patent segmentations and hyperlinks to an updated online database.
• Global patenting trends, including time evolution of patent publications, countries of patent filings, etc.
• Main patent assignees and IP newcomers grouped by geographical area.
• Focus on selected key IP players' portfolios
• Patents categorized by type of cathode active material (Li Ternary Oxides, Li Phosphates, Other CAM, Li & Li Precursors).

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, legal status of patent applications, helping 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, Knowmade's 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 Mining 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, KnowMade's 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 patents applications, patent assignees, filing countries, and technological segment 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).
