Aqueous rechargeable zinc‐ion batteries (ARZIBs) are promising energy storage systems owing to their ecofriendliness, safety, and cost‐efficiency. However, the sluggish Zn2+ diffusion kinetics originated from its inherent large atomic mass and high polarization remains an ongoing challenge. To this end, electrodes with 3D architectures and high porosity are highly desired. This work reports a rational...
High‐Ni‐rich layered oxides [e.g., LiNixCoyMnzO2; x > 0.5, x + y + z = 1] are considered one of the most promising cathodes for high‐energy‐density lithium‐ion batteries (LIB). However, extreme electrode–electrolyte reactions, several interfacial issues, and structural instability restrict their practical applicability. Here, a shortened unconventional atomic surface reduction (ASR) technique is...
Achieving facile nucleation of noble metal films through atomic layer deposition (ALD) is extremely challenging. To this end, η4‐2,3‐dimethylbutadiene ruthenium(0) tricarbonyl (Ru(DMBD)(CO)3), a zero‐valent complex, has recently been reported to achieve good nucleation by ALD at relatively low temperatures and mild reaction conditions. The authors study the growth mechanism of this precursor by in...
Miniaturized electronics suffer from a lack of energy autonomy. In that context, the fabrication of lithium‐ion solid‐state microbatteries with high performance is mandatory for powering the next generation of portable electronic devices. Here, the fabrication of a thin film positive electrode for 3D Li‐ion microbatteries made by the atomic layer deposition (ALD) method and in situ lithiation step...
The emerging potassium‐tellurium (K‐Te) battery system is expected to realize fast reaction kinetics and excellent rate performance due to the exceptional electrical conductivity of Te. However, there has been a lack of fundamental knowledge about this new K‐Te system, including the reaction mechanism and cathode structure design. Herein, a two‐step reaction pathway from Te to K2Te3 and ultimately...
Single‐atom catalysts (SACs) can achieve excellent catalytic efficiency at ultralow catalyst consumptions. Herein, platinum (Pt) atoms are fixed on the wall of atomic layer deposition (ALD)‐made molybdenum disulfide nanotube arrays (MoS2‐NTA) for efficient hydrogen evolution reaction (HER). More concretely, MoS2‐NTA with different nanotube diameters and wall thicknesses are fabricated by a sacrificial...
Reported herein is a highly active and durable hydrogen evolution reaction (HER) electrocatalyst, which is constructed following a tandem interface strategy and functional in alkaline and even neutral medium (pH ≈ 7). The ternary composite material, consisting of conductive nickel foam (NF) substrate, Ni3S2‐MoS2 heterostructure, and TiO2 coating, is synthesized by the hydrothermal method and atomic...
Alkali metals are regarded as the most promising candidates for advanced anode for the next‐generation batteries due to their high specific capacity, low electrochemical potential, and lightweight. However, critical problems of the alkali metal anodes, especially dendrite formation and interface stabilization, remain challenging to overcome. The solid electrolyte interphase (SEI) is a key factor affecting...
