“…2D graphene has been widely used to hybridizing with a variety of electrode materials for different energy storage systems, including Li‐ion batteries, supercapacitors, as well as ZIBs. [ 4 ] However, most of the previously‐reported graphene‐based materials, such as MnO 2 /graphene [ 34,35 ] and VO x /graphene [ 36,37 ] in ZIBs, are of powder nature, which demands for a slurry‐coating method. It should be noted that the conventional slurry paste using insulating binders and conductive additives in these studies may aggravate the weight problem and degrade the capacity delivery.…”

Batteries powering next‐generation flexible and wearable electronic devices require superior mechanical bendability and foldability. Herein, a self‐standing hybrid nanoarchitecture constructed by ultralong MnO2 nanowires and graphene nanosheets as an advanced and lightweight cathodes for flexible and foldable zinc‐ion batteries (ZIBs) is designed and fabricated. The new‐designed batteries exhibit not only a high energy density of 436 Wh kg−1 based on the total cathode mass but also good 2000‐cycling durability. More importantly, the shape‐deformable ZIBs can be operated without any capacity loss under both bent and folded circumstances. The foldable ZIBs with high energy density and long lifetime hold great promise for smart and wearable electronics.

“…The research on energy storage and conversion has widely focused on sustainable energy technologies such as water electrolysis, fuel cells, solar power panels, metal–air/ion batteries, and wind power. [ 1–5 ] Among diverse renewable energy devices, fuel cells, especially liquid alcohol fuel cells (AFCs), have received much attention due to their high energy density, minimal environmental hazards, compact design, quick start‐up time, low operating temperature, and ease of handling. [ 6–7 ] Significant research has been focused primarily on the commercialization of direct methanol (C1) fuel cells (DMFCs) due to their high energy density, rich supply, renewability, and easy affordability.…”

The development of efficient and highly durable materials for renewable energy conversion devices is crucial to the future of clean energy demand. Herein, cage‐like quasihexagonal structured platinum nanodendrites decorated over the transition metal chalcogenide core (CoS2)‐N‐doped graphene oxide (PtNDs@CoS2‐NrGO) through optimized shape engineering and structural control technology are fabricated. The prepared electrocatalyst of PtNDs@CoS2‐NrGO is effectively used as anodic catalyst for alcohol oxidation in direct liquid alcohol fuel cells. Notably, the prepared PtNDs@CoS2‐NrGO exhibits superior electrocatalytic performance toward alcohol oxidation with higher oxidation peak current densities of 491.31, 440.25, and 438.12 mA mgpt–1 for (methanol) C1, (ethylene glycol) C2, and (glycerol) C3 fuel electrolytes, respectively, as compared to state‐of‐the‐art Pt‐C in acidic medium. The electro‐oxidation durability of PtNDs@CoS2‐NrGO is investigated through cyclic voltammetry and chronoamperometry tests, which demonstrate excellent stability of the electrocatalyst toward various alcohols. Furthermore, the surface and adsorption energies of PtNDs and CoS2 are calculated using density functional theory along with the detailed bonding analysis. Overall, the obtained results emphasize the advances in effective precious material utilization and fabricating techniques of active electrocatalysts for direct alcohol oxidation fuel cell applications.

“…[36,224,[236][237][238][239] On the other hand, according to the number of composite phases, the composite materials can be divided into two-phase composite and multiphase composite. Besides, from the view of functional phase component in composite, the highly conductive component is usually indispensable such as carbon cloth, [240] graphene, [241] CNTs, [242,243] and reduced graphene oxide (rGO). [244,245] Among them, the carbon-based materials can perform multifunctions as follows: 1) act as conductive network to provide more conductive pathway, and greatly boost the interface electron transport kinetics; 2) act as robust substrate to effectively alleviate the self-stacking or aggregation of active materials, and improve the utilization of active materials; 3) act as buffer structure to inhibit the volume variation of active materials during cycling.…”

have also greatly aroused the positive exploration of alternative LIB technologies in recent years. [44] In contrast to the flammable organic electrolyte in LIBs, the aqueous one exhibits lower cost, higher safety, and especially the superior ionic conductivity, which is generally two orders of magnitude higher than that of the organic system. [9,10] All those unparalleled advantages would make the aqueous battery technologies to be the promising candidates in the future. [11] Rechargeable aqueous zinc-ion batteries (AZIBs), which is mainly composed of zinc metal anode, zinc salt-based aqueous electrolyte, and Zn 2+ host cathode, hold the great promise for energy storage applications in very recent years. [12,13] Compared with nonaqueous alkali-ion batteries, the use of cheap and high ambient stable zinc metal anode and inexpensive aqueous electrolyte with superior ionic conductivity (Figure 1a) would make such type of battery to be one of the most promising commercial candidates in the future market. [14-17] To date, extensive studies have been reported for AZIBs, and relating publications have dramatically increased especially in these two years, as shown in Figure 1b. However, the insufficient energy density seems to become the bottleneck that hinder their practical applications at current status. [4,5,18] Such issue could be ascribed to the narrow operating voltage of aqueous electrolyte, insufficient electrochemical performance of cathode materials, and Zn anode. [13,19,20] Besides, the influence of other components such as separator and collector also should be considered to some extent. [20,21] Among them, the studies of widening operating voltage of electrolyte and the optimization of other components only received less attention, which still remain at the early stage. [22,23] On the contrary, more attentions were paid to the electrochemical performance tuning of electrode materials. [24-26] Besides, considering the fixed operating voltage of Zn metal anode, the modification of cathode materials seems to provide more possibilities to effectively improve the energy density of AZIBs, owing to their rich material systems. [20,26,27] Under these considerations, the rational design of advanced cathodes is expected to be a preferential task to develop. Up to now, many types of materials have been exploited as cathode candidates and applied for AZIBs, however, those Rechargeable aqueous zinc-ion batteries (AZIBs) have attracted extensive attention and are considered to be promising energy storage devices, owing to their low cost, eco-friendliness, and high security. However, insufficient energy density has become the bottleneck for practical applications, which is greatly influenced by their cathodes and makes the exploration of high-performance cathodes still a great challenge. This review underscores the recent advances in the rational design of advanced cathodes for AZIBs. The review starts with a brief summary and evaluation of cathode material systems, as well as the introduction of proposed storage mechani...
