The Recycling of Lithium-Ion Batteries LiCoO2 Cathode: Balancing Sustainability and Efficiency
We are all users of lithium-ion batteries (LIBs), the electrochemical energy storage devices that revolutionized our life, making the diffusion of portable and wearable devices possible and now driving the switch from a combustion engine to electric vehicles in the transportation sector. These positive trends are however leading to two whiplash effects: the issue related to management of LIBs when they reach the end of their life (EoL-LIBs) and the supply of the critical raw materials (CRMs) needed to produce the essential LIBs’ components. Recycling of EoL-LIBs is the answer to these two problems, addressing the aspects of waste management while providing a secondary source of CRMs needed to produce new LIBs, in a closed-loop circular economy scheme. The proposed laboratory activity is specifically focused on the recycling of LiCoO2, the most diffused cathode material and also the one containing the highest amount of CRMs. The students will be called to analyze the degradation procedure through acidic leaching, comparing the method today mostly exploited at industrial level (using inorganic acid) and the method recently proposed in the scientific literature (exploiting organic acids). Students will be called to consider not only quantitative chemical indicators (yields of degradation and recovery of CRMs) but also the cost, safety, and disposal of the procedure. The aim of this experience is to drive the students to critically consider all aspects related to sustainability, to present them the tools to quantitatively assess it, and to create awareness regarding a technology involved in our everyday life.
期刊介绍:
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
