Abstract Sodium metal batteries (NMBs) have attracted increasing attention as next‐generation rechargeable batteries. How to improve their cycling stability and safety under limited sodium excess conditions, ideally zero (i.e., anode‐free architecture), is highly desired yet remains challenging. Herein, it demonstrated that formate (HCOONa), one component of the solid electrolyte interphase (SEI) naturally formed on anode, a promising candidate for designing high‐performance artificial SEI...
A titanium–oxo cluster-reinforced gel polymer electrolyte is developed to improve the performance of high-sulfur-loading lithium–sulfur batteries under lean conditions.
A cake making strategy is developed to prepare reduced graphene oxide wrapped plant fiber sponges for high-efficiency solar steam generation.
Abstract Designing copper (Cu) current collectors is a convenient way to stabilize lithium (Li) metal anodes. However, Cu and their derived Li/Cu anodes still face several obstacles, including lithiophobic oxidizable surface, cumbersome anode fabrication process, low Li utilization. Here, formate‐treatment strategy presented reconstruct with passivation layer covered Cu(110) surface. This method can easily be generalized increase the lithiophilicity oxidation resistibility of collectors....
Room-temperature sodium-sulfur (RT-Na-S) batteries are attracting increased attention due to their high theoretical energy density and low-cost. However, the traditional RT-Na-S assembled with glass fiber (GF) separators still hindered by polysulfide shuttle effect sodium dendrite growth, limiting battery's capacity cycling stability. Here, a facile effective method toward commercial polyolefin for constructing stable is presented. By coating polypropylene membrane core-shell structured...
A hybrid micromotor is an active colloid powered by more than one power source, often exhibiting expanded functionality and controllability those of a singular energy source. However, these sources are applied orthogonally, leading to stacked propulsion that just sum two independent mechanisms. Here, we report TiO2–Pt Janus micromotors, when subject both UV light AC electric fields, move up 90% faster simply adding the speed either This unexpected synergy between propose, arises from fact...
The metallic sodium (Na) is characterized by high theoretical specific capacity, low electrode potential and abundant resources, its advantages manifests itself as a promising candidate anode of metal batteries (SMBs). However, the vaporization during plating/stripping or uncontrolled growth dendrites in anodes (SMAs) has posed major challenges to practical applications. To address this issue, here, SnO2 /Ti3 C2 Tx composite rationally fabricated, which sodiophilic nanoparticles are situ...
Sodium metal, with its high theoretical capacity, low redox potential, and cost-effectiveness, presents a promising anode candidate for next-generation high-energy-density batteries. However, the development of Na metal anodes is significantly challenged by issues such as uncontrolled dendrite growth, volume expansion, associated safety concerns. Designing developing advanced materials to enhance conductivity sodium promote uniform ion deposition are urgent importance. Herein, MXene-based...

We report nonintrusive optical microscopy measurements of single micrometer-sized silica and polystyrene colloids in inhomogeneous AC electric fields as a function field amplitude frequency. By using Boltzmann inversion the time-averaged sampling particles within fields, we sensitively measure induced dipole-field interactions on kT energy scale fN force scale. Measurements are reported for frequencies when particle polarizability is greater less than medium, well crossover between these...

Carbon-coated silicon micro- and nanostructures have been widely used as composite anodes for lithium-ion batteries combining the benefits of high theoretical capacity Si better conductivity carbon. To optimize structures that allow volume expansion without losing electrical connection, a detailed carbon protection mechanism is desired. We fabricate network interconnected sandwich branches with thin film encapsulated between porous 3-dimensional graphene foam drapes (so-called ensemble)....
