“…Very recently, Huang et al reported the construction of nanoporous densely stacked graphene films derived from 3D graphene aerogels (3D GAs), prepared by the self‐propagating combustion reduction of GO aerogels in seconds, which were used as a high‐capacity, ultrafast, and binder‐free cathode for AIBs (Figure 16e). [ 318 ] The obtained films showed high SSA, an expanded interlayer spacing, nanoporous structure, and excellent flexibility, delivering a high capacity of 245 mAh g −1 at 1 A g −1 , exceptional cycling stability, superior rate capability, and stable operation over a wide temperature range. Importantly, these AIBs showed both surface adsorption charge storage and ion intercalation mechanisms, because the high SSA provided efficient adsorption sites for AlCl 4 − , and the large interlayer spacing obtained by the thermal reduction favored ion intercalation.…”

Graphene and graphene oxide (GO), as wonder materials, have penetrated nearly every field of research. One of their most attractive features is the functionality and assembly of graphene or GO, in which they can be considered to be chemically functionalized building blocks for creating unconventional porous graphene materials (PGMs) that not only combine the merits of both porous materials and graphene, but also have major advantages over other porous carbons for specific applications. The chemistry and approaches for functionalizing graphene and GO are first introduced, and typical procedures for pore creation (e.g., in-plane pores, 2D laminar pores, and 3D interconnected pore assemblies), self-assembly, and tailoring mechanisms for PGMs to highlight the significance of precise control over the pore morphology and pore size are summarized. Because of their unique pore structures, with different morphologies and intriguing properties, PGMs serve as key components in a variety of applications such as energy storage, electrocatalysis, and molecular separation. Finally, the challenges relating to PGMs from the understanding of chemical self-assembly to specific applications are discussed, and promising solutions on how to tackle them are presented. This provides an insightful outlook for the future development of the chemistry and applications of PGMs.

“…[49] Subsequently, 250 mg of rGO aerogel was immersed into 2 m KOH (100 mL) for 24 h. The resultant dispersion was then filtrated by vacuum deposition, and the collected black slurry was dried in a vacuum oven at 45 °C for 48 h. Subsequently, the obtained black powder at a horizontal tube furnace was heated to 800 °C for 1 h with an argon flow of 50 mL min −1 . Typically, GO solution (6 mg mL −1 ) was freeze-dried to form GO aerogel.…”

With the relentless development of smart and miniaturized electronics, the worldwide thirst for microscale electrochemical energy storage devices with form factors is launching a new era of competition. Herein, the first prototype planar sodium‐ion microcapacitors (NIMCs) are constructed based on the interdigital microelectrodes of urchin‐like sodium titanate as faradaic anode and nanoporous activated graphene as non‐faradaic cathode along with high‐voltage ionogel electrolyte on a single flexible substrate. By effectively coupling with battery‐type anode and capacitor‐type cathode, the resultant all‐solid‐state NIMCs working at 3.5 V exhibit a high volumetric energy density of 37.1 mWh cm−3 and an ultralow self‐discharge rate of 44 h from V max to 0.6 V max, both of which surpass most reported hybrid micro‐supercapacitors. Through tuning graphene layer covered on the top surface of interdigital microelectrodes, the NIMCs unveil remarkably enhanced power density, owing to the establishment of favorable multidirectional fast ion diffusion pathways that significantly reduce the charge transfer resistance. Meanwhile, the as‐fabricated NIMCs present excellent mechanical flexibility without capacitance fade under repeated deformation, and electrochemical stability at a high temperature of 80 °C because of using nonflammable ionogel electrolyte and in‐plane geometry. Therefore, these flexible planar NIMCs with multidirectional ion diffusion pathways hold tremendous potential for microelectronics.

In this paper, we designed a novel rechargeable Al−Ni battery. Nickel foil was firstly used as a cathode material for aluminum batteries and realized a reversible electrode reaction in a weak Lewis acidic electrolyte. Al−Ni battery can provide a high discharge capacity of more than 0.4 mA h cm−2 and exhibit excellent stability. Furthermore, the electrode reaction mechanism and proposed reasonable reaction equations of Al−Ni battery was studied deeply. We also explored the failure process of Al−Ni batteries and obtained the composition of side reaction products. This Al−Ni battery could offer a high reversible capacity of 0.66 mA h at a current density of 0.5 mA cm−2. Even at 1 mA cm−2, it still delivers a capacity of 0.415 mA h (0.27 mA h cm−2) after 100 cycles.
