“…In aqueous electrolytes, supercapatteries show smaller specific energy because of the smaller operational cell voltage, but they are advantageous in terms of specific power. Table 1 summarises various combinations of capacitive and faradaic electrode materials, and lists the reported performance of the electrochemical energy storage devices, including the supercapacitors [15][16][17][18][19][20], supercapatteries [5,8,[17][18][19][20][21][22] and batteries [23]. Recent progress on the high energy capacity electrode materials is also discussed.…”

Redox electrode materials, including transition metal oxides and electronically conducting polymers, are capable of faradaic charge transfer reactions, and play important roles in most electrochemical energy storage devices, such as supercapacitor, battery and supercapattery. Batteries are often based on redox materials with low power capability and safety concerns in some cases. Supercapacitors, particularly those based on redox inactive materials, e.g. activated carbon, can offer high power output, but have relatively low energy capacity. Combining the merits of supercapacitor and battery into a hybrid, the supercapattery can possess energy as much as the battery and output a power almost as high as the supercapacitor. Redox electrode materials are essential in the supercapattery design. However, it is hard to utilise these materials easily because of their intrinsic characteristics, such as the low conductivity of metal oxides and the poor mechanical strength of conducting polymers. This article offers a brief introduction of redox electrode materials, the basics of supercapattery and its relationship with pseudocapacitors, and reviews selectively some recent progresses in the relevant research and development.

“…As shown in Figure 3c, Klankowski et al proposed a novel battery-pseudocapacitor system composed of a silicon-coated aligned carbon nanofiber (ACNF) anode and a titanium oxide coated ACNF cathode. [43] The aligned structure and the coreshell structure of the electrodes provided good electrical connection and fast lithium ion transport, leading to a remarkable high rate performance. The battery-pseudocapacitor had a high energy density of 103 Wh kg −1 at a current density of 74 mA g −1 and an excellent power density of 56 kW kg −1 at 7.4 A g −1 , which is comparable to batteries at low current rates and supercapacitors at high current rates.…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smll.202007676. Fast-charging batteries have attracted great attention, and are anticipated to charge electrical vehicles and consumer electronics to full-capacity in several minutes. However, commercial electrode materials in batteries generally have a limited rate performance and are difficult to be used in fast-charging batteries. Designing electrodes with an aligned structure is an effective way to shorten the ion transport path and improve the rate performance of a battery. The excellent electronic conductivity of carbon-based electrodes is another key factor for increasing the rate capability of rechargeable batteries. Therefore, aligned carbon-based electrodes (ACBEs) can significantly improve the power density by combining the advantages of an aligned structure and carbon-based materials. In this review, the mechanism, advantages, and challenges of ACBEs for fast-charging batteries are evaluated, and then the design and preparation methods of ACBEs based on their different dimensions are summarized, and their applications in different batteries are illustrated. Finally, the future development of ACBEs for fast-charging batteries is considered.

“…It is well known that systems containing battery electrodes are completely degraded before 1200 cycles [34]. Different hybrid supercapacitors published in the literature are evaluated in about 1000 cycles and they never reach the same performance of the electrochemical capacitors with purely electrostatic mechanism [33][34][35][36]. For this reason, the cycling performance for CNT|1M H 2 SO 4 , 1M VOSO 4 |||EAN|MES can be considered acceptable.…”

A novel strategy for the development of high energy density supercapacitors (SC) is explored. The new devices contain two electrolytes that are different in nature, an aqueous electrolyte in one half-cell and an ionic liquid in the other. These systems, referred to as biliquid SCs, make it possible to combine the best electrode/electrolyte in terms of individual electrode capacitance and cathodic/anodic stability limits.Furthermore, other asymmetries that combine different electrodes, electrolytes and storage mechanisms can be incorporated. Synchronous cyclic chronopotenciometry was used to monitor the performance of these novel complex systems. It is expected that this approach will help scientists working in this field to develop new devices that overcome the energy density limitations of current SCs, thereby extending the scope of their application.
