The latter depends on successful developments of new materials, battery units and battery system optimization. This calls for radical changes in the methodology from the currently commonly used trial-and-error to rational designs based upon fundamental understanding of underlying physics and chemistry. This series papers will discuss various aspects including thermodynamic, kinetic, interfacial, materials, battery units and systems, and characterization techniques. This will hopefully shed some light on the research and development of new chemical energy storage technologies particularly batteries. This is the first paper in the series and will discuss the energy densities of bat
