“…by rationally employing lamellar reverse micelles (Figure 1). [98][99][100][101][102] Later, Xiao et al developed another strategy to synthesize 2D metal oxide nanosheets from solution by using the surfaces of water-soluble salt crystals as growth substrates or templates. In the synthesis, inverse lamellar micelles of Pluronic P123 polymer with a cosurfactant were used to confine the growth of the metal oxide along the thickness dimension and resulted in an atomic-level thickness of the obtained nanosheets.…”

The exponential increase in research focused on two-dimensional (2D) metal oxides has offered an unprecedented opportunity for their use in energy conversion and storage devices, especially for promising next-generation rechargeable batteries, such as lithium-ion batteries (LIBs) and sodium-ion batteries (NIBs), as well as some post-lithium batteries, including lithium-sulfur batteries, lithium-air batteries, etc. The introduction of well-designed 2D metal oxide nanomaterials into next-generation rechargeable batteries has significantly enhanced the performance of these energy-storage devices by providing higher chemically active interfaces, shortened ion-diffusion lengths, and improved in-plane carrier-/charge-transport kinetics, which have greatly promoted the development of nanotechnology and the practical application of rechargeable batteries. Here, the recent progress in the application of 2D metal oxide nanomaterials in a series of rechargeable LIBs, NIBs, and other post lithium-ion batteries is reviewed relatively comprehensively. Current opportunities and future challenges for the application of 2D nanomaterials in energy-storage devices to achieve high energy density, high power density, stable cyclability, etc. are summarized and outlined. It is believed that the integration of 2D metal oxide nanomaterials in these clean energy devices offers great opportunities to address challenges driven by increasing global energy demands.

“…For SOC-3, the initial discharge and charge capacities were 1650 and 1050 mA h g À1 , respectively, all the three materials revealed initial coulombic efficiency of less than 70%, due to the incomplete conversion involved in the formation of the solid electrolyte interphase (SEI) and the decomposition of the electrolyte. 18,51,52 From the second cycle, the coulombic efficiencies were all nearly 99%, demonstrating good reversible electrochemical property. Aer 150 cycles at a current of 100 mA g À1 , these materials exhibited steady performances of 585, 823 and 1058 mA h g À1 for SOC-1, SOC-2 and SOC-3, respectively (Fig.…”

“…One is to assemble active materials into different nanostructures, such as nanowires, nanobers, nanococoons, hollow spheres and so on. [11][12][13][14][15][16][17][18] The low dimensional nanostructures can effectively accommodate the structure strain, and the large exposed surface can shorten the diffusion distance of lithium ion, which is benecial to high rate capability. The second one is to combine carbon structure with SnO 2 .…”

N-Doped-carbon-coated 2-4 nm SnO 2 nanoparticles were synthesized via a facile metal-organic framework (MOF) coating process followed by a calcination of the SnO 2 @MOF composite. The asprepared SnO 2 nanoparticles are well dispersed and coated with a uniform nitrogenous carbon structure, which can effectively prevent volume expansion during discharge and charge processes. Benefiting from the advantages of a synergistic effect of SnO 2 nanoparticles and carbon structure, these materials exhibit excellent electrochemical performance. For the optimized material SOC-3, a reversible specific capacity of 1032 mA h g À1 was maintained at 100 mA g À1 after 150 cycles with a coulombic efficiency of 99%.When the current was increased to 500 mA g À1 , a capacity of 600 mA h g À1 was still attained.

“…The rapid development of lithium ion batteries (LIBs) offers an unprecedented opportunity to meet the increasing requirements for the various electric/electronic devices. The limited energy density of LIBs (≈400 Wh kg −1 ) and their unsatisfying safety, unfortunately, are the major challenges for further expanding their practical application in the various potential fields, such as electric vehicles (EVs) with a long driving range . Even though the energy density can be considerably enhanced by replacing the current Li‐ion configuration into a Li–O 2 configuration that directly utilizes lithium metal and oxygen gas as the anode and cathode active species, there is still no doubt that the safety and cost issues can hardly be overcome due to the unavoidable involvement of scarce metallic lithium in these Li‐based battery chemistries .…”

The success of Li–air/O2 batteries has brought extensive attention to the development of various promising non‐Li metal–O2 batteries, such as Zn–O2, Al–O2, Mg–O2 batteries, etc., which have exhibited unique advantages, such as low production cost, high energy density, and much enhanced safety. The versatile non‐Li metal–O2 batteries provide a better opportunity for meeting the practical requirements for sustainable energy supplies in various applications. A high‐performance cathode in non‐Li metal–O2 batteries that can effectively trigger both oxygen reduction and evolution reactions and thus boost the overall battery performance is of great research interest. In this article, a comprehensive review on the development of Li‐free metal–O2 batteries and particularly focusing on the oxygen catalytic cathodes for both primary and secondary non‐Li metal–O2 batteries is carefully performed. The current challenges and potential solutions are also outlined and proposed. Through carefully selecting and rationally designing promising catalytic cathodes, a series of non‐Li metal–oxygen batteries toward practical energy storage applications are highly anticipated.
