Band 7, Heft 1

Self-discharge as an omnipresent and unwelcome feature of electrochemical storage devices driven by fundamental forces is briefly introduced and put into perspective. Causes and observed effects as well as possible consequences and modifications in support of a therapy of these effects are described. Care is taken to consider observed phenomena with respect to different types of supercapacitors and different classes of electrode materials and additives inside a cell. Modeling and further theoretical approaches are presented. Recommendations for reporting and data presentation are provided.

The suitability of three electrochemical methods commonly used for the assessment of efficiency of corrosion inhibitors in practical applications has been examined by a direct comparison of relevant results with an aromatic corrosion inhibitor as example. Discrepancies between results are discussed, practical approaches taking inherent weaknesses of the methods are indicated.
