Electrochemical energy storage is a process in which energy is stored in chemical bonds through the conversion of electrical energy into chemical energy. Electric vehicle applications require batteries with high energy density and fast-charging capabilities. This chapter describes the basic principles of electrochemical energy storage and discusses three important types of system: rechargeable batteries, fuel cells and. . The different storage technologies can be classified on the basis of the different methodologies utilized: electrochemical (lead-, nickel-, high temperature salts-, redox-batteries, hydrogen. electrical (capacitors, supercapacitors). Although some storage technologies could work for several. .
