ABSTRACT

This chapter provides insights into “communications” and “co-ordinations” between the basic knowledge pertaining to chemistry, electrochemistry, and materials science, for translating the same into technologies corresponding to electrochemical energy storage (i.e., supercapacitors and batteries) and associated usages of the same at the various levels. Electrochemical energy storage is based on basic electrochemical principles, leading to the storage of energy in the form of electrical charge either on the surface or within the bulk of the electrode material in the charged condition, which can be “harnessed” during discharging. Accordingly, the electrochemical performance of electrode materials depends significantly on, not only the composition and crystal structure, but also on the associated cation co-ordination and basic bonding characteristics, including the crystal field stabilization/splitting energy.
