Lithium iodide reaction at cathode
WebHere, we present fabrication of a reduced graphene oxide (rGO)/LiI composite cathode, enabling for the first time the use of LiI as the Li-ion battery cathode. LiI was coated on … WebIn this practical, students get the chance to practise doing electrolysis with a range of solutions, identifying the products that form at the electrodes. They should be able to link their practical experience with theory and learn how to construct simple ionic equations. The class experiment is best done by students working in pairs or threes.
