A Simple Method for Identifying the Thermodynamic Limits to the Specific Energy of Electrochemical Energy Storage Systems

Abstract

<p></p><p>This article outlines a simple method for identifying the thermodynamic limits to electrochemical reversible energy storage systems based on the Nernst equation and previous results obtained from work on reversible chemical hydrogen sorption. The model is successfully validated for seven reversible battery cell examples. The findings of this work substantiate the idea of a general thermodynamic principle limiting reversible chemical energy storage and suggest a change of paradigm towards a global understanding of the matter.</p><br><p></p>
