Ultra-high nickel cobalt-free lithium layered oxides are promising cathode material for lithium-ion batteries（LIBs） because of their relatively high capacity and low cost.Nevertheless,the high nickel content would induce bulk structure degradation and interfacial environment deterioration,and the absence of Co element reduces the lithium diffusion kinetics,severely limiting the performance liberation of this kind of cathodes.Herein,a multifunctional Ti/Zr dual cation co-doping strategy has been employed to improve the lithium storage performance of LiNi0.9Mn0.1O2（NM91） cathode.On the one hand,the Ti/Zr co-doping weakens the Li+/Ni2+mixing through magnetic interactions due to the inexistence of unpaired electrons for Ti4+and Zr4+,increasing the lithium diffusion rate and suppressing the harmful coexistence of H1 and H2 phases.On the other hand,they enhance the lattice oxygen stability because of the strong Ti-O and Zr-O bonds,inhibiting the undesired H3 phase transition and lattice oxygen loss,improving the bulk structure and cathode-electrolyte interface stability.As a result,the Ti/Zr co-doped NM91（NMTZ） exhibits a 91.2% capacity retention rate after 100 cycles,while that of NM91 is only82.9%.Also,the NMTZ displays better rate performance than NM91 with output capacities of 115 and93 mA h g-1at a high current density of 5 C,respectively.Moreover,the designed NMTZ could enable the full battery to deliver an energy density up to 263 W h kg-1,making the ultra-high nickel cobaltfree lithium layered oxide cathode closer to practical applications.

High density and safe storage of hydrogen are the preconditions for the large-scale application of hydrogen energy.Herein,the hydrogen storage properties of Ti_(0.6)Zr_(0.4)Cr_(0.6)Mn_(1.4) alloys are systematically studied by introducing Y element instead of Ti element through vacuum arc melting.After the partial substitution of Y,a second phase of rare earth oxide is added in addition to the main suction hydrogen phase,C14 Laves phase.Thanks to the unique properties of rare earth elements,the partial substitution of Y can not only improve the activation properties and plateau pressure of the alloys,but also increase the effective hydrogen storage capacity of the alloys.The comprehensive properties of hydrogen storage alloys are improved by multidimensional regulation of rare earth elements.Among them,Ti_(0.552)Y_(0.048)Zr_(0.4)Cr_(0.6)Mn_(1.4) has the best comprehensive performance.The alloy can absorb hydrogen without activation at room temperature and 5 MPa,with a maximum hydrogen storage capacity of 1.98 wt.%.At the same time,it reduces the stability of the hydride and the enthalpy change value,making it easier to release hydrogen.Through theoretical analysis and first-principle simulation,the results show that the substitution of Y element reduces the migration energy barrier of hydrogen and the structural stability of the system,which is conducive to hydrogen evolution.The alloy has superior durability compared to the original alloy,and the capacity retention rate was 96.79%after 100 hydrogen absorption/desorption cycles.

Aqueous zinc-based battery is usually plagued by serious dendrites and side reactions including Zn corrosion and water decomposition on the anode.To address the drawbacks,constructing coating layers with high conductivity and anti-catalytic effects on hydrogen evolution reaction has been considered as an efficient strategy.Herein,cheap and abundant twodimensional(2D)conductive graphite(KS-6)coating layer with high electronic conductivity(~106 S·m^(−1))could directly form strong bonding with Zn foil due to high zincophilicity,which correspondingly protects Zn metal from liquid electrolyte to inhibit parasitic hydrogen evolution and guide uniform Zn electrodeposition during cycling.The KS-6 layer owns a profitable charge redistribution effect to endow Zn anode with a lower nucleation energy barrier and a more uniformly distributed electric field compared with bare Zn.Therefore,such integrated Zn anode exhibits low voltage hysteresis(~38 mV)and excellent cycling stability with dendrite-free behaviors(1 mA·cm^(−2)and 2 mAh·cm^(−2))over 2,000 h,far outperforming many reported Zn metal anodes in aqueous systems.Encouragingly,in light of the superior Zn@KS-6 anode,VNOx powders and Prussian blue analogs Mn_(2)Fe(CN)_(6)are applied as the cathode materials to assemble full batteries,which show remarkable cycling stabilities and high Coulombic efficiencies(CEs)over 200 cycles with capacity retention of 81.5%for VNOx//Zn@KS-6 battery and over 400 cycles with capacity retention of 94.6%for Mn_(2)Fe(CN)_(6)//Zn@KS-6 battery,respectively.

High-voltage medium-nickel low-cobalt lithium layered oxide cathode materials are becoming a popular development route for high-energy lithium-ion batteries due to their relatively high capacity,low cost,and improved safety.Unfortunately,capacity fading derived from surface lithium residue,electrode-electrolyte interfacial side reactions,and bulk structure degradation severely limits large-scale commercial utilization.In this work,an ultrathin and uniform NASICON-type Li_(3)V_(2)(PO_(4))_(3)(LVP)nanoscale functional coating is formed in situ by utilizing residual lithium to enhance the lithium storage performance of LiNi_(0.6)Co0.05Mn_(0.35)O_(2)(NCM)cathode.The GITT and ex-situ EIS and XPS demonstrate exceptional Li+diffusion and conductivity and attenuated interfacial side reactions,improving the electrode-electrolyte interface stability.The variable temperature in-situ XRD demonstrates delayed phase transition temperature to improve thermal stability.The battery in-situ XRD displays the singlephase H1-H2 reaction and weakened harmful H3 phase transition,minimizing the bulk mechanical degradation.These improvements are attributed to the removal of surface residual lithium and the formation of NASICON-type Li_(3)V_(2)(PO_(4))_(3)functional coatings with stable structure and high ionic and electronic conductivity.Consequently,the obtained NCM@LVP delivers a higher capacity retention rate(97.1%vs.79.6%)after 150 cycles and a superior rate capacity(87 mAh·g^(-1)vs.58 mAh·g^(-1))at a 5 C current density than the pristine NCM under a high cut-off voltage of 4.5 V.This work suggests a clever way to utilize residual lithium to form functional coatings in situ to improve the lithium storage performance of high-voltage medium-nickel low-cobalt cathode materials.

Aluminum hydride is a promising chemical hydrogen storage material that can achieve dehydrogenation under mild conditions as well as high hydrogen storage capacity.However,designing an efficient and cost-effective catalyst,especially a synergistic catalyst,for realizing low-temperature and high-efficiency hydrogen supply remains challenging.In this study,the heterojunction synergistic catalyst of Ti_(3)C_(2)supported PrF_(3)nanosheets considerably improved the dehydrogenation kinetics of AlH_(3)at low temperatures and maintained a high hydrogen storage capacity.In the synergistic catalyst,Pr produced a synergistic coupling interaction through its unique electronic structure.The sandwich structure with close contact between the two phases enhanced the interaction between species and the synergistic effect.The initial dehydrogenation temperature of the composite is reduced to 70.2℃,and the dehydrogenation capacity is 8.6 wt.%at 120℃ in 90 min under the kinetic test,which reached 93%of the theoretical hydrogen storage capacity.The catalyst considerably reduced the activation energy of the dehydrogenation reaction.Furthermore,the multielectron pairs on the surface of the catalyst promoted electron transfer and accelerated the reaction.

Complex hydride LiAlH_(4),as a hydrogen storage material,possesses high theoretical hydrogen storage capacity(10.5 wt.%).However,highly efficient additives are urgently required to modify its thermal stability and sluggish kinetics.Some additives exhibit unique morphology-dependent characteristics.Herein,the efficient rare earth oxide nano-CeO_(2)additives with different morphologies(nanoparticles,nanocubes,and nanorods)are prepared by the hydrothermal method,and the intrinsic properties are characterized.The three different morphologies of nano-CeO_(2),which are different in the Ce^(3+)content and specific surface area,are added to LiAlH_(4)to improve the dehydrogenation behavior.The LiAlH_(4)-CeO_(2)-nanorod composite exhibits the optimal dehydrogenation behavior,which begins to desorb hydrogen at 76.6℃ with a hydrogen capacity of 7.17 wt.%,and 3.83 wt.%hydrogen is desorbed within 30 min at 140℃.The dehydrogenation process of the composites demonstrates that hydrogen release is facilitated by the in-situ formed CeH_(2).73 and the facile transition between the oxidation states of Ce^(4+)and Ce^(3+).Combined with density functional theory calculations,the addition of nano-CeO_(2)can weaken the Al-H bond and accelerate the decomposition of[AlH_(4)]^(4-)tetrahedron,which is consistent with the reduction of the decomposition activation energy.

Chinese Journal of Mechanical Engineering 2023年第3期36卷 302-314页

Autonomous-rail rapid transit(ART)is a new medium-capacity rapid transportation system with punctuality,comfort and convenience,but low-cost construction.Combined velocity planning is a critical approach to meet the requirements of energy-saving and punctuality.An ART velocity pre-planning and re-planning strategy based on the combination of punctuality dynamic programming(PDP)and pseudospectral(PS)method is proposed in this paper.Firstly,the longitudinal dynamics model of ART is established by a multi-particle model.Secondly,the PDP algorithm with global optimal characteristics is adopted as the pre-planning strategy.A model for determining the number of collocation points of the real-time PS method is proposed to improve the energy-saving effect while ensuring computation efficiency.Then the enhanced PS method is utilized to design the velocity re-planning strategy.Finally,simulations are conducted in the typical scenario with sloping roads,traffic lights,and intrusion of the pedestrian.The simulation results indicate that the ART with the proposed velocity trajectory optimization strategy can meet the punctuality requirement,and obtain better economy efficiency compared with the punctuality green light optimal speed advisory(PGLOSA).

Physiological but not morphological adjustments along latitudinal gradients in a human commensal species,the Eurasian tree sparrow

Human commensal species take advantage of anthropogenic conditions that are less likely to be challenged by the selective pressures of natural environments.Their morphological and physiological phenotypes can therefore dissociate from habitat characteristics.Understanding how these species adjust their morphological and physiological traits across latitudinal gradients is fundamental to uncovering the eco-physiological strategies underlying coping mechanisms.Here,we studied morphological traits in breeding Eurasian tree sparrows(ETSs;Passer montanus)among low-latitude(Yunnan and Hunan)and middle-latitude(Hebei)localities in China.We then compared body mass;lengths of bill,tarsometatarsus,wing,total body,and tail feather;and baseline and capture stress-induced levels of plasma corticosterone(CORT)and the metabolites including glucose(Glu),total triglyceride(TG),free fatty acid(FFA),total protein,and uric acid(UA).None of the measured morphological parameters varied with latitude except in the Hunan population,which demonstrated longer bills than those in other populations.Stress-induced CORT levels significantly exceeded baseline levels and decreased with increasing latitude,but total integrated CORT levels did not vary with latitude.Capture stress-induced significantly increased Glu levels and decreased TG levels,independent of site.However,the Hunan population had significantly higher baseline CORT,baseline and stress-induced FFA levels,but lower UA levels,which differed from other populations.Our results suggest that rather than morphological adjustments,physiological adjustments are mainly involved in coping mechanisms for middle-latitude adaptation in ETSs.It is worth investigating whether other avian species also exhibit such dissociation from external morphological designs while depending on physiological adjustments.
