ELECTROCHEMICAL ENERGY STORAGE
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".
