“…When combined with rGO, the MnO 2 @rGO core-shell nanowires show an increased reversible capacity of 242 mA h g −1 and enhanced rate performance. [63] Chong et al synthesized a K-ion intercalated α-MnO 2 (KMO) nanorod material, where the K-ions located in the 2 × 2 channels (inset of Figure 4g). To increase the electrochemical conductivity of KMO, the material was combined with carbon nanotube (CNT) (30 wt%), forming a KMO/CNT-30 hybrid material.…”

etc., is essentially crucial to help combat these hazards and build a sustainable society. Among them, rechargeable battery has been regarded as a key technology. In the past decade, we have witnessed that the prevailing lithium-ion batteries (LIBs) made our society more portable, intelligent, and cleaner. [17][18][19] Nevertheless, the limited lithium resources and rising cost hinder their applications in the long run, especially in the field of large-scale stationary energy storage for renewable energy resources (e.g., solar, tide, and wind power). Thus, it is a huge stimulus for researchers to explore more sustainable rechargeable battery systems, which are expected to involve abundant and nontoxic metals to reduce the cost and impacts on environment.Diversified rechargeable batteries such as, the monovalent sodium-ion batteries (SIBs), [20][21][22][23][24] potassium-ion batteries (PIBs), [25][26][27] bivalent zinc-ion batteries (ZIBs), [28][29][30][31] magnesium-ion batteries (MIBs), [32][33][34][35] calcium-ion batteries (CIBs), [36][37][38][39] and trivalent aluminum-ion batteries (AIBs), [40][41][42] have emerged and shown great energy storage promise. As depicted in Figure 1a, those nonlithium metals are much more abundant than Li, especially Al, Ca, Na, K, and Mg, all of which rank the top-8 abundant elements in earth crust. For SIBs and PIBs, since Al would not form alloys with Na and K, Al foil can be used as anode collector, which further lowers the prices of SIBs and PIBs. On the other hand, the higher standard potential of Na/Na + (−2.71 V vs standard hydrogen electrode, SHE) and K/K + (−2.93 V) and their heavier atomic weights make energy densities of SIBs and PIBs intrinsically lower than that of LIBs. For multivalent-ion batteries, the multielectron transfer enables their volumetric capacities (e.g., 5857 and 8056 mA h cm −3 for Zn and Al, respectively) higher than that of Li (2042 mA h cm −3 ). [43,44] Additionally, the small cation radius of Zn 2+ (0.74 Å), Mg 2+ (0.72 Å), and Al 3+ (0.54 Å) indicate that many intercalation electrode materials typical in LIBs may be also potential hosts for reversible intercalation of these multivalent ions. Combining all the above merits, one can anticipate that these emerging rechargeable batteries would be considered as promising alternatives to LIBs.In quest of safe, cost-effective, and high-performance rechargeable batteries, two technical routes have been

“…In addition, TMO-based heterostructures were also prepared as electrode materials for PIBs. [58,126] For example, the hierarchical TiO 2 /C tubular heterostructures were synthesized as anodes for PIBs. [58] DFT calculations and density of state data indicated that the TiO 2 /C heterostructures had a lower energy barrier for potassium storage and a higher conductivity than those of TiO 2 ÀC hybrids.…”

Owing to the cost-effectiveness, Earth abundance, and suitable redox potential, potassium-ion batteries (PIBs) stand out as one of the best candidates for largescale energy storage systems. However, the large radius of K þ and the unsatisfied specific capacity are the main challenges for their commercial applications. To address these challenges, constructing heterostructures by selecting and integrating 2D materials as host and other materials as guest are proposed as an emerging strategy to obtain electrode materials with high capacity and long lifespan, thus improving the energy storage capability of PIBs. Recently, numerous studies are devoted to developing 2D-based heterostructures as electrode materials for PIBs, and significant progress is achieved. However, there is a lack of a review article for systematically summarizing the recent advances and profoundly understanding the relationship between heterostructure electrodes and their performance. In this sense, it is essential to outline the promising advanced features, to summarize the electrochemical properties and performances, and to discuss future research focuses about 2D-based heterostructures in PIBs.

“…However, as mentioned above, they also suffer from low electronic conductivity in addition to fast capacity fading, which originates from substantial volume change during the conversion reaction. Their performances have been improved through the addition of various carbonaceous materials and their use is not limited to LICs [72]. More promising within this class are functional structures of BMTOs, like NiCo 2 O 4 , which have shown a good specific capacitance at high rate, paving the way for high power density LICs.…”

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.
