Modern human societies, living in the second decade of the 21st century, became strongly dependant on electrochemical energy storage (EES) devices. Looking at the recent past (~ 25 years), energy storage devices like nickel-metal-hydride (NiMH) and early generations of lithium-ion batteries (LIBs) played a pivotal role in enabling a new era
One of the challenges with electrochemical grid-scale storage technologies lies in testing and modeling battery performance and degradation over the relevant timescale of 20+ years.

The storage capability of an electrochemical system is determined by its voltage and the weight of one equivalent (96500 coulombs). If one plots the specific energy (Wh/kg) versus the g-equivalent ( Fig. 9 ), then a family of lines is obtained which makes it possible to select a "Super Battery".
