Abstract
This review focuses on the extraction of lithium-ions (Li+) from the cathode of spent lithium-ion batteries (SLIB) and application of the delithiated cathode in catalytic reactions. Li+ has been extracted from SLIB through electrochemical and chemical leaching methods. Despite challenges for extraction of Li+, delithiated cathode materials demonstrate substantial catalytic efficiency in water electrolysis, dye photodegradation, and photoelectrochemical applications. This enhanced catalytic performance is attributable to the favorable catalytic properties of the transition metal oxide components and numerous catalytically active defects and oxygen vacancies formed by delithiation. The findings underscore the potential of recycling SLIBs into valuable catalysts for environmental and energy-related applications, emphasizing the transformation of waste into resource through efficient material reutilization.
期刊介绍:
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
