Abstract The high‐entropy materials (HEM) have attracted increasing attention in catalysis and energy storage due to their large configurational entropy multiunique properties. However, it is failed alloying‐type anode Li‐inactive transition‐metal compositions. Herein, inspired by concept, the Li‐active elements instead of ones are introduced for metal‐phosphorus synthesis. Interestingly, a new Zn x Ge y Cu z Si w P 2 solid solution successfully synthesized as proof which first verified...
Hard carbons hold considerable promise as anode materials for sodium-ion batteries. Nevertheless, their inadequate closed pores are detrimental to the filling and extraction of Na+, which leads poor plateau capacity during charging discharging processes hinders progress application high-energy carbon anodes essential accelerating commercialization SIBs. In this work, we proposed a convenient co-carbonization strategy aimed at synthesizing hard–soft composite featuring plenty pores,...
Fe7S8 with large capacity shows high potential for Li-ion batteries, while it still suffers volume expansion, resulting in fast fading. Herein, a novel yolk-shell structural Fe7S8@C-N is rationally designed, which the N-doped carbon layer superior mechanical flexibility enables one to accommodate expansion of core and promote its electronic transportation. Besides, surface porous morphology believed facilitate electrolyte infiltration diffusion as well. Therefore, this modified electrode...
Abstract The monoclinic GeP with large capacity, low plateau, and high initial coulombic efficiency (ICE) has been proved to be alternative anode for Li‐ion batteries. However, the heavy use of Ge raw material its price, hinders further development. Herein, Zn atom is proposed substitution into replaces part owing suitable similar radius. Interestingly, a novel 1−x x P solid solution wide range tunable region (0.143 < 0.6) achieved, reducing cutting price down. More intriguingly, such...
Counting shrimp larvae is an essential part of farming. Due to their tiny size and high density, this task exceedingly difficult. Thus, we introduce algorithm for counting densely packed utilizing enhanced You Only Look Once version 5 (YOLOv5) model through a regional segmentation approach. First, the C2f convolutional block attention modules are used improve capabilities YOLOv5 in recognizing small shrimp. Moreover, employing technique can decrease receptive field area, thereby enhancing...
The layered GeP shows great advantages for high-energy Li-ion batteries (LIBs) owing to its large capacity and suitable plateau. However, the morphology of nanosheets is difficult obtain since recent always synthesized by a ball-milled method, resulting in serious amorphous features failure smart design flexible devices. Herein, ultra-thin are successfully prepared scale first synthesizing single-crystal via typical flux method following fast electrochemical exfoliation. Compared traditional...
In this work, we report a novel two-dimensional (2D) (SrBr)2PbI4 perovskite layered architecture, which were formed by the reaction of strontium bromide (SrBr2), iodide (SrI2) and lead (PbI2). Formation 2D was verified small angle XRD peak at 6.4°, corresponds to layer distance 13.78 Å. The best one solar cells fabricated with Quasi-3D perovskite, (SrBr)2FA59Pb60I181 (n = 60), showed power conversion efficiency (PCE) 18.46% retained 95% initial PCE 1000 h in dry air. Further, as surface...
The alloying type materials have been proposed to be served as the alternative anode for lithium ion batteries (LIBs) owing their much higher capacity than graphite. However, those elementray substances still suffer large volume expansion, resulting in Li-irreversibility of low initial coulombic efficiency (ICE<75%) and fast fading. Herein, inspired by high entropy concept, we extend simple elements into alloy (HEA) system rational designing Li-active conductive components. Interestingly,...
The emerging SiP2 with large capacity and suitable plateau is proposed to be the alternative anode for Li-ion batteries. However, typical still suffers serious volume expansion structural destruction, resulting in much Li-consumption fading. Herein, a new novel stretchable conductive Li-PAA@PEDOT:PSS binder rationally designed improve SiP2's cyclability reversibility. Interestingly, such hydrogel enables better accommodation of than PVDF (e.g. 5.94% vs 68.73% expansivity). More specially,...
Metal-halide perovskite solar cells (PSCs) have attracted considerable attention during the past decade. However, due to existence of non-radiative recombination losses, best power conversion efficiency (PCE) is still lower than theoretical limit defined by Shockley-Queser theory. In this work, we investigate 1,2,3-oxathiazin-4(3h)-one, 6-methyl-2,2-dioxide (acesulfame potassium, abbreviated as AK) a additional dopant for 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene...
