“…[152] Going one step further, the method to prepare Si trapped in gelatin-derived carbon was proposed by Wang et al The Si trapped in gelatin-derived carbon was directly assembled into lithium-ion capacitor without the addition of binder and conductive agent, which achieved predominant areal capacity of 2.81 mAh cm À2 at 0.18 mA cm À2 , comparable with that of the commercial lithium-ion battery (LIB) and good rate stability. [153] Since the exploitation of Si and its derivatives as potential electrode materials, the same concept has been used to probe the electrochemical property of Sn-based materials. It was demonstrated that Co 2 P/Sn encapsulated with nitrogen-doped carbon nanobox was a promising anode material for sodium-ion capacitor (Figure 8).…”

High power density supercapacitors that use reversible ion adsorption to store charge at the electrode/electrolyte interface remain functional after hundreds of charge/discharge cycles. [1][2][3] A series of carbonaceous materials such as activated carbon, graphite, fullerenes, graphene, and mesoporous carbon have been proposed to boost the performance of supercapacitors. [4,5] Among them, activated carbons with large specific surface area (%3000 m 2 g À1 ) are favored in supercapacitor designs by forming an electric double layer, thus ensuring the long-term stability. [6] Nevertheless, they offer a relatively low energy density. The capacity of supercapacitors is far from meeting the requirements for powering a variety of ubiquitous portable and flexible electronic devices. Limited gravimetric and volumetric energy densities remain serious issues for the commercialization of supercapacitor. Apart from supercapacitor, battery is another important component of energy storage system. Compared with the performance of supercapacitor, battery shows a low power density because the chemical reactions occur within the electrode material. Considering these limitations, research focus has been desperately put on the metal-ion hybrid capacitor (MHC) combining the merits of battery and supercapacitor. The setup of MHC is composed of capacitor-type and battery-type electrode materials. [41][42][43][44][45] A large part of the advantage of MHCs is due to their higher energy density than supercapacitors and higher power density than batteries without sacrificing cycling stability. [46][47][48][49][50] Using the concept of MHC is to both store and deliver large amounts of energy in devices. Therefore, MHCs have been extensively investigated. However, the high reactivity of alkali metals and the rising cost of scarce lithium resources have driven us to develop multivalent MHCs. Multivalent MHCs possess the merits of abundant resources, high safety, and high energy density owing to their multielectron energy storage process. Few studies have focused on describing a comprehensive review of MHCs, including Li, Na, K, Zn, Mg, Ca, and Al ion capacitors. Therefore, this review is concerned with research activities on electrode materials for MHC and provides a perspective on the future development of electrochemical energy storage technology.

“…Likewise, the use of Si can be improved through the engineering of other components of electrodes such as binders. For instance, the use of gelatin-derived carbon as a binder and as conductive additive substantially improved the performance of LICs primarily due to the provided elasticity which delivered more structural stability to the Si-based electrode [83].…”

Advanced and Emerging Negative Electrodes for Li-Ion Capacitors: Pragmatism vs. Performance

Li-ion capacitors (LICs) are designed to achieve high power and energy densities using a carbon-based material as a positive electrode coupled with a negative electrode often adopted from Li-ion batteries. However, such adoption cannot be direct and requires additional materials optimization. Furthermore, for the desired device’s performance, a proper design of the electrodes is necessary to balance the different charge storage mechanisms. The negative electrode with an intercalation or alloying active material must provide the high rate performance and long-term cycling ability necessary for LIC functionality—a primary challenge for the design of these energy-storage devices. In addition, the search for new active materials must also consider the need for environmentally friendly chemistry and the sustainable availability of key elements. With these factors in mind, this review evaluates advanced and emerging materials used as high-rate anodes in LICs from the perspective of their practical implementation.

A porous and fluffy Si@C‐network electrode, in which the Si nanoparticles contact with the carbon conductive network, is prepared by an in‐situ carbonization method on a copper collector. Si nanoparticles are uniformly embedded in the 3‐dimensional fluffy carbon network, which could suppress the capacity decay resulting from the Si volume expansion during the cycling process. The Si@C‐network electrode with a high ratio (83.4 wt %) of active Si exhibits long‐term cycling stability (capacity retention of 765 mAh g−1 after 700 cycles at 2100 mA g−1) and good rate performance. The superior electrochemical performance is attributed to the continuous conductive network, which improves the conductivity of electrode and maintains the electrode structure well after 100 cycles.
