Recently, electrode materials with both battery-type and capacitive charge storage are significantly promising in achieving high energy and high power densities, perfectly fulfilling the rigorous requirements of metal-ion batteries and electrochemical capacitors as the next generation of energy storage devices.
More specifically, electrode materials with both battery-type and capacitive charge storage are traditional electrode materials for metal ion batteries in their bulk states, and the capacitive charge storage is apparent only with rationally engineering the architectures of electrode materials.
Until now, nano-structuration, hetero-interface, and surface doping are the most widely used three strategies to combine battery-type and capacitive charge storage in electrode materials.
In this technology, charge storage is achieved through a reversible redox reaction within the electrode surface [ 17, 63, 70 ]. Metal oxides, such as RuO 2 [ 71] and MnO 2 [ 72 ], and conducting polymers are the main class of electrode materials used for charge storage in pseudocapacitors [ 73, 74 ].
Only when the cost drops and the active material loading increases to the degree of commercialization, it is very likely that the electrochemical energy storage device based on these electrode materials will become an important supplement or even replacement to the existing LIBs and ECs.
Synthesizing and fabricating carbon electrode materials to their full potential is crucial for their effective use in electrochemical applications. Researchers employ a wide range of techniques to alter carbon compounds' structure, content, and characteristics to make them more effective energy storage devices.
