The batteries can be charged and discharged. This relies on the movement of lithium ions in the electrolyte through a semipermeable barrier and electrons in an external circuit. Over time, the battery performance decreases from repeated insertion of lithium ions into the graphite structure.
Over time, the battery performance decreases from repeated insertion of lithium ions into the graphite structure. The questions may be used at the end of the topic, either in class or as homework, to reinforce understanding of electrochemical cells and identify misconceptions. Hints are provided for some questions to aid differentiation.
It’s so easy, get started today. The cathode in a lithium-ion cell is made of lithium cobalt oxide (LiCoO 2) and the anode is made of graphite (C). Oxidation always occurs at the anode (AN OX) and reduction at the cathode (RED CAT). The batteries can be charged and discharged.
