The main properties of energy storage materials, especially those of batteries, are capacity, electric potential, rate, and reversibility. They are determined by structures defined by the above-mentioned fundamental degrees of freedom, as shown in Figure 1.
Researchers developing the next generation of energy storage systems are challenged to understand and analyze the different charge storage mechanisms, and subsequently use this understanding to design and control materials and devices that bridge the gap between high specific energy and power at a target cycle life.
Electrochemical charge storage in a confined space is often interpreted as either electrostatic adsorption or Faradaic intercalation. Here the authors propose that the storage mechanism is a continuous transition between the two phenomena depending on the extent of ion solvation and ion–host interaction.
This perspective can be used as a guide to quantitatively disentangle and correctly identify charge storage mechanisms and to design electrochemical interfaces and materials with targeted performance metrics for a multitude of electrochemical devices.
From the perspective of orbital structure, 4f and 5d element-incorporated materials and oxygen redox are definitely promising topics in the energy storage material community. 72, 73 As for the characterization method for orbital structures, DPC, 4D-STEM, and CBED are powerful methods to detect the charge distribution.
Since the first commercialized lithium-ion battery was developed in 1990, many researchers and companies have focused on the study of energy storage materials. 1 Different kinds of materials such as oxide electrodes, silicon anodes, solid-state electrolytes, lithium-air batteries, and different kinds of cells and package designs have been studied.
