Charge storage mechanisms for electric energy storage (EES) devices and the types of EES devices with their characteristic electrochemical behavior. (A) Schematic descriptions of the four major mechanisms: the electrical double-layer formation, the bulk redox reaction, the surface near redox reaction, and the redox activity of the electrolyte.
Over recent decades, a new type of electric energy storage system has emerged with the principle that the electric charge can be stored not only at the interface between the electrode and the electrolyte but also in the bulk electrolyte by redox activities of the electrolyte itself.
... Electrochemical energy storage (EES) devices, such as rechargeable batteries and supercapacitors, are attracting much attention because of their high efficiency, durability and the abilities to power a wide range of mobile and stationary applications from large-scale energy storage to miniaturized sensors.
All-solid-state battery has attracted significant attention as a promising next-generation energy storage. However, interfacial resistance of ion transport between the positive electrode and solid electrolyte is still a crucial issue for the all-solid-state battery commercialization.
Difference between the redox potentials of the PE and anode corresponds to the cell voltage, and the electrochemical window of the electrolyte material is crucial for battery safety. On the other hand, the electrode active materials are typically semiconductors (or semimetals), and the SEs have electronic insulating characters.
There have been several experimental findings for the interface resistance. Ohta et al 10, 11, Takada et al 12, 13, and Takada found that charging starts at a lower voltage than that for the PE material in sulfide SE cases, and introduction of an oxide buffer layer at the interface remedies this behavior.
