As electrical autos and vitality storage methods (ESS) change into more and more widespread, the administration and recycling of spent lithium-ion batteries has emerged as a urgent world problem. Conventional recycling strategies, corresponding to energy-intensive smelting or chemically aggressive moist processes, require important vitality and pose environmental dangers.
A analysis staff led by Dr. Yosep Han on the Korea Institute of Geoscience and Mineral Assets (KIGAM) has efficiently developed an eco-friendly electrochemical course of to upcycle lithium manganese oxide (LiMn₂O₄, LMO), a typical cathode materials in spent lithium-ion batteries. This course of was immediately built-in right into a zinc–manganese redox circulation battery (Zn–Mn RFB), a promising next-generation vitality storage system, demonstrating its sensible feasibility.
The paper is revealed within the journal Small.
In contrast to standard recycling that focuses on metallic restoration, this technique electrochemically converts LMO into manganese ions (Mn²⁺), that are then used as electrolytes for redox circulation batteries. The staff’s innovation represents a considerable shift towards value-added…
