Abstract Rechargeable aluminum‐ion batteries have drawn considerable attention as a new energy storage system, but their applications are still significantly impeded by critical issues such low density and the lack of excellent electrolytes. Herein, high‐energy aluminum‐manganese battery is fabricated using Birnessite MnO 2 cathode, which can be greatly optimized divalence manganese ions (Mn 2+ ) electrolyte pre‐addition strategy. The exhibits remarkable 620 Wh kg −1 (based on material)...
Using lithium as the anode material to achieve high energy density lithium-ion/metal batteries is ultimate goal of storage technology. A recent development solid state electrolytes (SSEs) with ionic conductivity holds great promise for enabling practical applications metal (SSLMBs), mechanical strength SSEs can be harnessed suppress dendrite growth. However, application SSLMBs hampered by new multifold problems from solid–solid contact dendrites deleterious interfacial reactions between and...
S-rich MoS2–NCNF hybrid nanomaterials exhibiting extraordinary HER activity, with a very low onset potential of 30 mV and small Tafel slope 38 per decade, were successfully fabricated by combining N-doped carbon nanofibers single-layered MoS2 nanostructures abundant edge active sites.
Nanocrystalline (NC) metals are stronger and more radiation-tolerant than their coarse-grained (CG) counterparts, but they often suffer from poor thermal stability as nanograins coarsen significantly when heated to 0.3 0.5 of melting temperature (Tm). Here, we report an NC austenitic stainless steel (NC-SS) containing 1 at% lanthanum with average grain size 45 nm ultrahigh yield strength ~2.5 GPa that exhibits exceptional up 1000 °C (0.75 Tm). In-situ irradiation 40 dpa at 450 ex-situ 108...
Triangular W(Se<sub>x</sub>S<sub>1−x</sub>)<sub>2</sub> nanoflakes uniformly dispersed on the surface of electrospun carbon nanofiber mats were synthesized. The hybrid catalyst directly used as hydrogen evolution cathodes and exhibit excellent HER performances.
PtCo/CNFs exhibit extraordinary catalytic activity and durability for hydrogen evolution reaction, even approaching the performance of commercial Pt/C catalyst, which can be attributed to alloy structure encapsulation PtCo nanoparticles in CNFs.
The two biggest promises of solid-state lithium (Li) metal batteries (SSLMBs) are the suppression Li dendrites by electrolyte (SSE) and realization a high-energy-density anode. However, LMBs have not met their expectations due to dendrite growth causing short-circuiting. In fact, grow even more easily in SSE than liquid electrolyte, but reason for this remains unclear. Here we report situ transmission electron microscopy observations penetration through "dead" formation dynamics SSLMBs. We...
There remain significant challenges in developing fast-charging materials for lithium-ion batteries (LIBs) due to sluggish ion diffusion kinetics and unfavorable electrolyte mass transportation battery electrodes. In this work, a mesoporous single-crystalline lithium titanate (MSC-LTO) microrod that can realize exceptional fast charge/discharge performance excellent long-term stability LIBs is reported. The MSC-LTO microrods are featured with structure interconnected pores inside the entire...

Nevertheless, elevated cut‐off voltage complex interface interactions have presented significant challenges that can lead to material degradation. Specifically, inevitable release of lattice oxygen highly reactive interface‐driven irreversible migration transition metal (TM) ions in LRO make construction a robust extremely...
Rose-petal-shaped MoS2 hierarchical nanostructures were designed and constructed using carbonized electrospun nanofibers as a template, which exhibit highly structure-sensitive properties for the hydrogen evolution reaction (HER). We first synthesized carbon nanofiber (CNF) mats by combining electrospinning carbonization processes, then CNF used substrate direct growth of nanocrystals via CVD method. By controlling morphology at nanoscale, we evolutions in structures preferentially exposed...
Layered cathode materials are commonly used in lithium and sodium ion batteries, but they prone to degradation under electrochemical cycling during battery operation. Here we report a new type of mechanism through the electrochemically induced mechanical buckling delamination cracking intercalation layers P2 Na0.7-Ni0.3Mn0.6Co0.1O2 (Na-NMC) material. Kinks form delaminated due severe local bending, each kink consists vertical array dislocations, resulting from an easy slip between transition...
