Research BackgroundWith the rapid development of renewable energy, electric vehicles, and portable electronic devices, efficient and fast charge/discharge energy storage devices have become one of the key technological bottlenecks. Dielectric capacitors, with their ultra-fast response speed (~μs) and long cycle life, are ideal for high power density storage systems. However, current high-perfo...

With the rapid evolution of the global electric vehicle (EV) industry towards the 800V high-voltage platform, key electronic components in automotive systems face stringent challenges. Dielectric capacitors, as core components for energy conversion, urgently need to achieve breakthroughs in energy storage density, charge/discharge efficiency, and cyclic stability. To address this critical natio...

Ultra-high-strength metallic materials are urgently required in aerospace and defense applications, where weight reduction and extreme load-bearing performance are critically important. Developing advanced alloys that simultaneously achieve ultra-high yield strength (σy ≈ 2 GPa) and appreciable uniform elongation (εu > 5%) has therefore emerged as a key research focus. To date, only a limite...

Atomic-scale manufacture is a critical technology required for future atomic-scale information devices. Among various techniques, scanning probe microscopy-based tip manipulation plays an essential role in atomic-scale manufacturing, enabling the construction and precise tuning of atomic structures with single-atom accuracy. For materials like graphene and other 2D materials, this technique all...

BackgroundThere is a significant demand for high-energy lithium-ion batteries (LIBs) with long cycle life, especially for electric vehicles. To achieve cell-level energy densities surpassing 400 Wh kg⁻¹, the ideal strategy is to pair high-voltage Ni-rich (NMC811) cathodes with silicon-majority-graphite (SmG, >1500 mAh g−1) anodes. Silicon offers a theoretical capacity far exceeding graphite, ...

Most engineering alloys are crystalline. When crystallization is bypassed by rapid quenching, the resulting alloy—though macroscopically indistinguishable from conventional metals—lacks long-range crystalline order (Fig. 1, left). A wide range of elements and combinations can form amorphous states, including elemental Ta and Au; binary, ternary, and multicomponent systems such as Ni–B, Cu–Z...

In aerospace, nuclear energy, and advanced manufacturing, structural materials must operate reliably from cryogenic to high temperatures. Conventional alloys face a persistent strength–ductility trade-off: strengthening typically comes at the expense of tensile elongation, and high-temperature strength degrades sharply. Refractory high-entropy alloys (RHEAs)—composed of high-melting elements ...

​Under China’s “dual-carbon” goals, photovoltaic and wind power are becoming central to the energy mix, yet their intermittency and volatility impede large-scale grid integration. Aqueous organic redox flow batteries (AORFBs) are an attractive storage solution because of their low cost, intrinsic safety, and decoupled power/energy design. Among anolytes, viologen derivatives are widely used...
