The design and construction of energy storage systems, such as batteries and supercapacitors, represent one of
the most pioneering research domains in scientific landscape. Consequently, electrolytes assume a pivotal role as
indispensable components, while a profound understanding of electrolyte chemistry and ion transfer pathways
through electrolyte emerges as a potent tool for optimizing storage device design. This field of knowledge, known
as coordination chemistry, elucidates the intricate interplay between ions, solvents, salts, and the electrolyte
matrix, comprising polymer chains and ceramics, thereby providing invaluable insights into potential ion
transport pathways. Thus, this discourse commences with an introduction and classification of electrolytes,
followed by an in-depth exploration of ion transfer pathways in each case. Furthermore, the impact of the matrix,
solvent, and salt on complex formation, ion coordination chemistry, and ionic conductivity is meticulously
examined, thereby enhancing comprehension of these fundamental aspects.
