Commercial applications of electrochemical cells

Electrochemical cells can be used as a commercial source of electrical energy. Cells can be non-rechargeable (irreversible), rechargeable or fuel cells. The simplified electrode reactions in a lithium cell: Positive electrode:  Li+ + CoO2 + e– → Li+[CoO2]– Negative electrode: Li → Li+ + e– Students should be able to: • use given electrode data to deduce the reactions occurring in non-rechargeable and rechargeable cells and

Electrode potentials and cells

IUPAC convention for writing half-equations for electrode reactions. The conventional representation of cells. Cells are used to measure electrode potentials by reference to the standard hydrogen electrode. The importance of the conditions when measuring the electrode potential, E (Nernst equation not required). Standard electrode potential, EƟ, refers to conditions of 298 K, 100 kPa and 1.00 mol dm-3 solution of ions. Standard electrode potentials
