| 1 | Lattice Boltzmann modeling of transport phenomena in fuel cells and flow batteries显示文摘Fuel cells and flow batteries are promising technologies to address climate change and air pollution problems. An understanding of the complex multiscale and multiphysics transport phenomena occurring in these electrochemical systems requires powerful numerical tools. Over the past decades, the lattice Boltzmann(LB) method has attracted broad interest in the computational fluid dynamics and the numerical heat transfer communities, primarily due to its kinetic nature making it appropriate for modeling complex multiphase transport phenomena. More importantly, the LB method fits well with parallel computing due to its locality feature, which is required for large-scale engineering applications. In this article, we review the LB method for gas–liquid two-phase flows, coupled fluid flow and mass transport in porous media, and particulate flows. Examples of applications are provided in fuel cells and flow batteries. Further developments of the LB method are also outlined. | Ao Xu Wei Shyy Tianshou Zhao | 2017 | Acta Mechanica Sinica2017，33，3： | 12 |
| 2 | Ab initio prediction and characterization of phosphorene-like SiS and SiSe as anode materials for sodium-ion batteries显示文摘In this work, a density functional theory(DFT) based first-principles study is carried out to investigate the potential of phosphorene-like SiS and SiSe monolayers as anode materials for sodium-ion(Na-ion) batteries. Results show that both SiS and SiSe have large adsorption energies towards single Na atom of 0.94 and 0.43 eV, owing to the charge transfers from Na to SiS or SiSe. In addition, it is found that the highest Na concentration for both SiS and SiSe is x = 1 with the chemical formulas of Na SiS and Na SiSe, corresponding to the high theoretical specific capacities for Na storages of 445.6 and 250.4 m Ah g^(-1), respectively. Moreover, Na diffusions are very fast and show strong directional behaviors on SiS and SiSe monolayers, with the energy barriers of only 0.135 and 0.158 eV, lower than those of conventional anode materials for Na-ion batteries such as Na_2Ti_3O_7(0.19 eV) and Na_3Sb(0.21 eV). Finally,although SiS and SiSe show semiconducting behaviors, they transform to metallic states after adsorbing Na atoms, indicating enhanced electrical conductivity during battery cycling. Given these advantages, it is expected that both SiS and SiSe monolayers are promising anode materials for Na-ion batteries, and in principle, other Na-based batteries as well. | Haoran Jiang Tianshou Zhao Yuxun Ren Ruihan Zhang Maochun Wu | 2017 | Science Bulletin2017，62，8： | 6 |
| 3 | Ab initio prediction of borophene as an extraordinary anode material exhibiting ultrafast directional sodium diffusion for sodium-based batteries显示文摘Density functional theory calculations and ab initio molecular dynamics simulations are performed to study the feasibility of using borophene, a newly synthesized two-dimensional sheet of boron, as an anode material for sodium-ion and sodium–oxygen batteries. The theoretical capacity of borophene is found to be as high as1,218 m Ah g–1(Na0.5B). More importantly, it is demonstrated that the sodium diffusion energy barrier along the valley direction is as low as 0.0019 e V, which corresponds to a diffusivity of more than a thousand times higher than that of conventional anode materials such as Na2Ti3O7 and Na3Sb. Hence, the use of borophene will revolutionize the rate capability of sodium-based batteries. Moreover, it is predicted that, during the sodiation process, the average open-circuit voltage is 0.53 V, which can effectively suppress the formation of dendrites while maximizing the energy density. The metallic feature and structural integrity of borophene can be well preserved at different sodium concentrations, demonstrating good electronic conductivity and stable cyclability. | Le Shi Tianshou Zhao Ao Xu Jianbo Xu | 2016 | Science Bulletin2016，61，14： | 6 |
| 4 | A Li-S battery with ultrahigh cycling stability and enhanced rate capability based on novel ZnO yolk-shell sulfur host显示文摘Currently,lithium-sulfur(Li-S)batteries still suffer from fast capacity decay,poor coulombic efficiency(CE)and short cycling lifespan,which result from the severe shuttle effect issue caused by high solubility and rapid diffusion of lithium polysulfides(Li PSs)in organic electrolytes.Here,yolk-shell zinc oxide(YSZn O)spheres are synthesized and for the first time,applied as a host for Li-S batteries to tackle this challenge.The polar Zn O exhibits high chemical anchoring ability toward Li PSs while the unique yolk-shell structure not only provides an additional physical barrier to Li PSs but also enables much more uniform sulfur distribution,thus significantly suppressing Li PSs shuttling effect meanwhile promoting sulfur conversion reactions.As a result,the YS-Zn O enables the Li-S battery to display an initial specific capacity of1355 m Ah g^(-1) and an outstanding capacity retention capability(~89.44%retention rate)even after 500 cycles with the average CE of~99.46%at the current of 0.5 C.By contrast,the capacity of conventional-Zn O-nanoparticles based battery severely decays to 472 m Ah g^(-1) after cycling for 500 times.More impressively,the S/YS-Zn O based Li-S battery can maintain a low decay rate of 0.040%every cycle and high average CE of 98.82%over 1000 cycles at 3 C. | Ruihan Zhang Maochun Wu Xinzhuang Fan Haoran Jiang Tianshou Zhao | 2021 | Journal of Energy Chemistry2021，30，4： | 5 |
| 5 | A novel energy storage system incorporating electrically rechargeable liquid fuels as the storage medium显示文摘We propose a novel concept of energy storage that incorporates electrically rechargeable liquid fuels made of electroactive species, known as e-fuels, as the storage medium. This e-fuel energy storage system comprises an e-fuel charger and an e-fuel cell. The e-fuel charger electrically charges e-fuels, while the efuel cell subsequently generates electricity using charged e-fuels whenever and wherever on demand.The e-fuel energy storage system possesses all the advantages of conventional hydrogen storage systems,but unlike hydrogen, liquid e-fuels are as easy and safe to store and transport as gasoline. The potential efuel candidates have been identified to include inorganic electroactive materials, organic electroactive materials, and suspension of solid electroactive materials. In this work, we demonstrate an example efuel energy storage system for large-scale energy storage using inorganic e-fuels composed of V^(2+)/V^(3+) and VO_2^+/VO_2^+ redox couples, and compare the performance of the e-fuel energy storage system with that of existing technologies. Results show that our e-fuel charger achieves a charge efficiency of as high as~94%, while the e-fuel cell is capable of delivering a peak power density of 3.4 W cm^(-2), which is 1.7 times higher than that of hydrogen fuel cells. More excitingly, the e-fuel energy storage system exhibits a round-trip efficiency of 80.0% and an electrolyte utilization of 83.0% at an ultra-high discharge current density of 1,000 mA cm^(-2), which are 19.9% and 67.3% higher than those of conventional vanadium redox flow batteries. This unprecedented performance allows a 27.0% reduction in the capital cost of the e-fuel energy storage system compared with that of vanadium redox flow batteries. | Haoran Jiang Lei Wei Xinzhuang Fan Jianbo Xu Wei Shyy Tianshou Zhao | 2019 | Science Bulletin2019，64，4： | 2 |

| 11 | Experimental Investigations on Boiling Heat Transfer Inside Miniature Circular Tubes Immersed in FC-72显示文摘To investigate the size effect on the characteristics of boiling heat transfer, boiling behavior of FC-72 in heated vertical miniature circular tubes immersed in a liquid pool was experimentally studied. Two AISI 304 stainless steel tubes with inner diameters of 1.10 mm and 1.55 mm correspondingly, were heated by swirled Ni-Cr wire heaters and sealed in Lucite blocks by silicon adhesive. Both the top and the bottom ends of the circular test sections were open to the liquid pool. The boiling curves and heat transfer coefficients were obtained experimentally. The boiling behaviors at the outlets of the miniature tubes were also visualized with a digital video camera. Experimental results show that the tube geometry has a significant effect on the boiling characteristics. Vapor blocking at the outlet of the smaller circular tube with a diameter of 1.10 mm caused severe boiling hysteresis phenomena. The CHF decreased with reducing in tube size. | Qincheng Bi Tianshou Zhao Yajun Guo Tingkuan Chen | 2002 | Journal of Thermal Science2002，11，4： | 1 |

| 18 | Monolayer MoS_(2)Fabricated by In Situ Construction of Interlayer Electrostatic Repulsion Enables Ultrafast Ion Transport in Lithium-Ion Batteries显示文摘High theoretical capacity and unique layered structures make MoS_(2)a promising lithium-ion battery anode material.However,the anisotropic ion transport in layered structures and the poor intrinsic conductivity of MoS_(2)lead to unacceptable ion transport capability.Here,we propose in-situ construction of interlayer electrostatic repulsion caused by Co^(2+)substituting Mo^(4+)between MoS_(2)layers,which can break the limitation of interlayer van der Waals forces to fabricate monolayer MoS_(2),thus establishing isotropic ion transport paths.Simultaneously,the doped Co atoms change the electronic structure of monolayer MoS_(2),thus improving its intrinsic conductivity.Importantly,the doped Co atoms can be converted into Co nanoparticles to create a space charge region to accelerate ion transport.Hence,the Co-doped monolayer MoS_(2)shows ultrafast lithium ion transport capability in half/full cells.This work presents a novel route for the preparation of monolayer MoS_(2)and demonstrates its potential for application in fast-charging lithium-ion batteries. | Meisheng Han Yongbiao Mu Jincong Guo Lei Wei Lin Zeng Tianshou Zhao | 2023 | Nano-Micro Letters2023，15，6： | 1 |

| 20 | Honeycomb‐like hierarchical porous silicon composites with dual protection for ultrastable Li‐ion battery anodes显示文摘Silicon offers a high theoretical specific capacity for anodic lithium storage.However,its applications are hindered by the electrode instability caused by the sharp volume change,and the limited rate performance resulted from the insulating property.Herein,we introduce a facile and fast method of preparing honeycomb‐like silicon‐based anodes(MXene‐Si@C)with porous structure using MXene and carbon‐coated silicon.The dual protection from both the surface coating and as‐formed interlayered vacant spaces ameliorate the volume expansion of the silicon and thus reinforce the mechanical stability of the electrode.In addition,the highly conducting MXene and the surface carbon coating form a hierarchical and consecutive electron‐conducting network with evidently reduced resistance.With this proposed composite,a high average Coulombic efficiency of 99.73%and high capacity retention of 82.4%after 300 cycles at 1 A/g can be achieved even with an areal loading around 1.5 mg/cm^(2).Coupled with an NCM523 cathode,the proof‐of‐concept full cell delivers a high capacity of 164.2mAh/g with an extremely high energy density of 574Wh/kg(based on the mass of the electrode materials)at 0.2 C and an excellent cyclability at 0.5 C of 100 cycles with decent capacity retention(80.28%). | Xudong Peng Cheng Xiong Yanke Lin Chen Zhao Tianshou Zhao | 2021 | SmartMat2021，2，4： | 1 |
