The ever-increasing environmental/energy crisis as well as the rapid upgrading of mobile devices had stimulated intensive research attention on promising alternative energy storage and conversion devices.Among these devices,alkali metal ion batteries,such as lithium-ion batteries (LIBs) had attracted increas-ing research attention due to its several advantages including,environmental friendliness,high power density,long cycle life and excellent reversibility.It had been widely used in consumer electronics,elec-tric vehicles,and large power grids et ac.Silicon-based (silicon and their oxides,carbides) anodes had been widely studied.Its several advantages including low cost,high theoretical capacity,natural abun-dance,and environmental friendliness,which shows great potential as anodes of LIBs.In this review,we summarized the recently progress in the synthetic method of silicon matrix composites.The empirical method for prelithiation of silicon-based materials were also provided.Further,we also reviewed some novel characterization methods.Finally,the new design,preparation methods and properties of these nano materials were reviewed and compared.We hoped that this review can provide a general overview of recent progress and we briefly highlighted the current challenges and prospects,and will clarify the future trend of silicon anode LIBs research.

Suppressing the nonradiative recombination in the bulk and surface of perovskite film is highly desired to improve the power conversion efficiency (PCE) and stability of halide perovskite solar cells (PSCs).In this study,a benzotriazole derivative (6-chlo
Lithium metal is the ultimate anode material for next-generation high-energy batteries.Yet,the practical application of lithium metal anodes is limited by the formation of Li dendrites and large volume changes.Herein,an effective multi-dimensional hybrid
Doping enables manipulation of both the electrical and optical properties of halide perovskites.Herein,we incorporated Te4+ into Cs2ZrCl6 single crystal,simultaneously preserving the vacancy-ordered struc-ture,to obtain an efficient yellow-emitting perovs
Conversion of levulinic acid and its esters into versatile y-valerolactone (GVL) is a pivotal and challenging step in biorefineries,limited by high catalyst cost,the use of hydrogen atmosphere,or tedious catalyst preparation and recycling process.Here we
Proton exchange membrane fuel cell and direct methanol fuel cells have gained more attention due to high-energy density,remarkable conversion efficiency,and low emission.However,their widely practi-cal application was hindered by the high usage,limited so
To better utilize the infrared (IR) region in sunlight for photovoltaic devices (PVs),upconversion nanoparticles (UCNPs) have been proposed to improve power conversion efficiency (PCE).However,researchers recently have found that the upconversion (UC) eff
The stability issue has become one of the main challenges for the commercialization of perovskite solar cells (PSCs).Formamidinium (FA)-based perovskites have shown great promise owing to their improved thermal and moisture stability.However,these perovsk
It is a great challenge to develop membrane materials with high performance and long durability for acid-alkaline amphoteric water electrolysis.Hence,the graphitic carbon nitride (g-C3N4) nanosheets were compounded with the (2,2\'-m-phenylene)-5,5\'-b
Searching new structured black phosphorus (BP) and exploring intriguing functions and applications have become a hot topic so far.Here,we introduce a novel Iso-type black phosphorus heterostructure guided by first principle calculation,which features uniq
Lithium-sulfur (Li-S) batteries are regarded as one of the promising candidates for the next-generation energy storage system owing to their high capacity and energy density.However,the durable operation for the batteries is blocked by the shuttle behavio
