Electrochemical reactions are chemical reactions in which an electron transfer is involved during the chemical changes. As electrons are involved, the electrochemical reactions can produce or convert electricity. This property is used in many applications including sensing, electrolysis, and electrochemical energy storage. Rechargeable batteries and supercapacitors are the primary candidates for Electrical energy storage. Cost, safety, cycle life, energy, and power are the key issues hampering the adoption of these technologies. This tutorial will provide an overview of the basic principles involved in electrochemical energy storage, followed by status of electrode materials for lithium-, sodium-ion batteries and supercapacitors. Particularly, the synthesis approaches, surface modification, electrode architecture, and optimum cell configurations to realize high-performance rechargeable batteries. In addition, a new hybrid Monte Carlo (MC)/molecular dynamics (MD) reaction method, called Red Moon method, will be introduced. This method was recently applied successfully to several secondary batteries and showed high efficiency to simulate the microscopic formation of solid electrolyte interface (SEI) film, including a succession of multiple elementary reaction processes, i.e. complex chemical reactions. Finally, the recent applications of Red Moon method will be presented, revealing the microscopic origin of ambiguous experimental observations as the mystery of additive effect.
