Advanced Materials for Energy Storage

Since the discovery of mechanically exfoliated graphene in 2004, research on ultrathin two-dimensional (2D) nanomaterials has grown exponentially in the fields of condensed matter physics, material science, chemistry, and nanotechnology. Highlighting their compelling physical, chemical, electronic, and optical properties, as well as their various potential applications, in this Review, we summarize the state-of-art progress on the ultrathin 2D nanomaterials with a particular emphasis on their recent advances. First, we introduce the unique advances on ultrathin 2D nanomaterials, followed by the description of their composition and crystal structures. The assortments of their synthetic methods are then summarized, including insights on their advantages and limitations, alongside some recommendations on suitable characterization techniques. We also discuss in detail the utilization of these ultrathin 2D nanomaterials for wide ranges of potential applications among the electronics/optoelectronics, electrocat...

Rational Design of a P2-Type Spherical Layered Oxide Cathode for High-Performance Sodium-Ion Batteries

Li metal anode is deemed the most promising candidate anode for high-energy battery systems such as Li-sulfur and Li-fluoride batteries. However, some severe challenges, for example, facile formation and growth of Li dendrites, large volume evolution of hostless Li ,and low Coulombic efficiency of Li plating/stripping, still hinder the commercialization of Li-metal batteries (LMBs). Herein, a free-standing and highly flexible 3D current collector made of carbon nanofibers (CNFs) conformally coated by continuous Sn layer is synthesized by electrospinning method. Sn layer enables a lithiophilic and alloyable carbon skeleton surface and provides uniform and continuous Li nucleation sites, leading to unusual conformal Li plating behavior and effective inhibition of Li dendrites. The spatial confinement of Li plating mitigates the volume expansion and network distortion of CNFs. The electric contact reinforced by Sn interlayer achieves highly reversible Li stripping for more than 850 h for CNF-Sn@Li symmetric ...

Unusual Conformal Li Plating on Alloyable Nanofiber Frameworks to Enable Dendrite Suppression of Li Metal Anode

Progress and Perspective of Metal- and Covalent-Organic Frameworks and their Derivatives for Lithium-Ion Batteries

Nanostructured SnO 2 and SnO 2 -graphite composites were prepared by microemulsion synthesis using Tergitol 15-S-5 as the surfactant. The size of the SnO 2 nanoparticles was typically between 15 and 20 nm. The graphite-SnO 2 composite containing 9.8 wt % SnO 2 showed a high reversible Li + storage capacity of 384 mAh/g which decreased by only 4% in 30 cycles. The substantial cyclability improvement relative to unsupported SnO 2 is believed to be due to the uniform dispersion of the SnO 2 nanoparticles on the graphite surface, which reduces particle aggregation during Li + insertion and extraction reactions.
