Patent published on the 2026-10-01 in US under Ref US20260299025 by TATA CONSULTANCY SERVICES LTD [IN] (Imran Mohammad [in], Purushothaman Madhan Mohan [in], Panchumarthi Narasimha Dilip [in], Kumar Anil Arvind [in])
Abstract: A robust circular economy for retired batteries is not just a sustainability goal but an economic and geopolitical necessity. However, conventional methods struggle to accurately identify diverse battery chemistries and degradation levels, limiting reuse potential. The present disclosure addresses the unresolved problems of the conventional methods by providing a system and method for end-of-life (EoL) battery pathway categorization using a multi-criteria decision-making algorithm. The present d[...]
Our summary: The system categorizes end-of-life batteries using a multi-criteria decision-making algorithm. It employs advanced techniques like X-Ray scanning and Electrochemical Impedance Spectroscopy for precise classification. This approach addresses limitations of conventional methods and enhances reuse potential in a circular economy.

Process and system for cathode active material recovery from lithium-ion battery cathode foil
Patent published on the 2026-09-03 in WO under Ref WO2026180943 by LOHUM MAT PRIVATE LIMITED [IN] (Joshi Gururaj [in], Negi Sanjay Singh [in], Tyagi Dushyant [in], Mandan Chidambaram [in], Safvi Syed Gazanfar Abbas [in], Verma Rajat [in])
Abstract: The present disclosure discloses a non-destructive, single-step process for recovering cathode active material (CAM) from spent lithium-ion battery (LIB) cathode foils while preserving the integrity of the aluminum foil. The method involves thermal pre-treatment at 250°C to weaken the binder, followed by immersion in a 3.5%-4.5% oxalic acid solution with 2%-3% hydrogen peroxide at 50°C-70°C under continuous stirring for 10-15 minutes. The reaction facilitates the separation of CAM from the al[...]
Our summary: This disclosure presents a non-destructive method for recovering cathode active material from lithium-ion battery foils. The process involves thermal pre-treatment followed by immersion in an oxalic acid solution, facilitating material separation. It ensures high purity, cost-effectiveness, and sustainability while minimizing environmental impact.
