| 1 | Boosting Lean Electrolyte Lithium-Sulfur Battery Performance with Transition Metals: A Comprehensive Review显示文摘Lithium–sulfur(Li–S) batteries have received widespread attention, and lean electrolyte Li–S batteries have attracted additional interest because of their higher energy densities. This review systematically analyzes the effect of the electrolyte-to-sulfur(E/S) ratios on battery energy density and the challenges for sulfur reduction reactions(SRR) under lean electrolyte conditions. Accordingly, we review the use of various polar transition metal sulfur hosts as corresponding solutions to facilitate SRR kinetics at low E/S ratios(< 10 μL mg~(-1)), and the strengths and limitations of different transition metal compounds are presented and discussed from a fundamental perspective. Subsequently, three promising strategies for sulfur hosts that act as anchors and catalysts are proposed to boost lean electrolyte Li–S battery performance. Finally, an outlook is provided to guide future research on high energy density Li–S batteries. | Hui Pan Zhibin Cheng Zhenyu Zhou Sijie Xie Wei Zhang Ning Han Wei Guo Jan Fransaer Jiangshui Luo Andreu Cabot Michael Wübbenhorst | 2023 | Nano-Micro Letters2023，15，10： | 2 |
| 2 | Sulfur-modified nickel selenide as an efficient electrocatalyst for the oxygen evolution reaction显示文摘The sluggish four-electron transfer of the oxygen evolution reaction(OER)limits the performance of water electrolyzers.Hence,OER electrocatalysts based on earth-abundant elements are urgently needed.Heteroatom doping has been an efficient approach to boost the intrinsic OER activity of the active sites by modifying the electronic structure.Here,a simple anion substitution strategy is reported that increases the OER activity of nickel selenides via a one-step hydrothermal treatment of a metal–organic framework precursor.The resulting S-substituted Ni_(3)Se_(4) nanoparticles display distortion of their crystal lattice.As expected,the sulfur substitution modifies the electronic structure of Ni_(3)Se_(4) and leads to outstanding electrocatalytic activity.All the S-substituted Ni_(3)Se_(4) catalysts exhibit higher OER activities than the original Ni_(3)Se_(4).The optimized catalyst achieves a current density of 10 mA cm^(−2) at an overpotential of 275 mV with a Tafel slope of 64 mV dec^(−1) in 1.0 M KOH.In addition to its electrochemical activity,the S-Ni_(3)Se_(4)-2 catalyst also exhibits good stability with only a 7.5%increase in overpotential at 50 mA cm^(−2) after 100 hours.This work demonstrates one strategy to modify the electronic structure of transition metal compounds by anion regulation. | Kai Wan Jiangshui Luo Xuan Zhang Palaniappan Subramanian Jan Fransaer | 2021 | Journal of Energy Chemistry2021，30，11： | 2 |
| 3 | Development of proton-conducting membrane based on incorporating a proton conductor 1,2,4-triazolium methanesulfonate into the Nafion membrane显示文摘In this paper, 1,2,4-triazolium methanesulfonate(C2H4N+3CH3SO-3, [Tri][MS]), an ionic conductor, was successfully synthesized. It exhibited high ionic conductivity of 18.60 m S cm-1at 140CdSC and reached up to 36.51 m S cm-1at 190CdSC. [Tri][MS] was first applied to modify Nafion membrane to fabricate [Tri][MS]/Nafion membrane by impregnation method at 150CdSC. The prepared composite membrane showed high thermal stability with decomposed temperature above 200CdSC in air atmosphere. In addition, the membrane indicated good ionic conductivity with 3.67 m S cm-1at 140CdSC and reached up to 13.23 m S cm-1at 180CdSC. The structure of the [Tri][MS] and the composite membrane were characterized by FTIR and the compatibility of [Tri][MS] and Pt/C catalyst was studied by a cyclic voltammetry(CV) method. Besides, the[Tri][MS]/Nafion membrane(thickness of 65 μm) was evaluated with single fuel cell at high temperature and without humidification. The highest power density of [Tri][MS]/Nafion membrane was 3.20 m W cm-2at 140CdSC and 4.90 m W cm-2at 150CdSC, which was much higher than that of Nafion membrane. | Jinkai Hao Xiaojin Li Shuchun Yu Yongyi Jiang Jiangshui Luo Zhigang Shao Baolian Yi | 2015 | Journal of Energy Chemistry2015，24，2： | 1 |

| 6 | Metal-organic framework-derived CoP_(2)@N-doped carbon hollow spheres for efficient oxygen evolution reaction显示文摘1.Introduction.Hydrogen is considered as a viable alternative to fossil fuels[1,2].Large-scale hydrogen production by electrochemical water splitting is regarded as an important approach.It consists of two half-reactions:hydrogen evolution reaction(HER)at the cathode and oxygen evolution reaction(OER)at the anode[3].Compared to the HER,the OER has sluggish kinetic and large overpotentials,re-sulting from the complex oxidation pathway[4,5].Although RuO_(2) and IrO_(2) have excellent catalytic OER performance[6],their large-scale deployment is unfeasible due to the scarcity and high cost of these noble metal elements.Thus,cheap OER electrocatalysts have been actively investigated[7]. | Wei Zhang Jiangshui Luo Xuan Zhang Wei Guo Ning Han Sijie Xie Zhenyu Zhou Zahid Anwer Zhenhong Xue Jan Fransaer | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
| 7 | Cobalt-embedded 3D conductive honeycomb architecture to enable high-sulphur-loading Li-S batteries under lean electrolyte conditions显示文摘High sulphur loading and lean electrolyte conditions are important to achieve the high theoretical energy density of lithiumsulphur(Li-S)batteries.However,serious problems such as low sulphur utilization and fast capacity fade are typically experienced under low electrolyte/sulphur(E/S)ratios and high sulphur loading conditions.To address these issues,a cobaltcontaining three-dimensional conductive honeycomb(Co@N-HPC)is proposed in this work as a material for sulphur cathodes.The good electrical conductivity and high density of catalytic sites of(Co@N-HPC)allow fast redox kinetics of lithium polysulfide(LiPS)in high-sulphur-loading electrodes.In addition,the hierarchical structure and good wettability by the electrolyte of Co@NHPC facilitates electrolyte penetration and LiPS conversion,leading to a high utilization of sulphur under lean electrolyte conditions.Therefore,at a current density of 0.2 C,a volumetric capacity of 1,410 mAh·cm^(−3)was attained with a sulphur loading of 5.1 mg·cm^(−2)and an E/S ratio of 5μL·mg^(−1).This work provides ideas for the development of lean electrolyte Li-S batteries with a high sulphur loading. | Hui Pan Zhibin Cheng Jan Fransaer Jiangshui Luo Michael Wübbenhorst | 2022 | Nano Research2022，15，9： | 0 |
| 8 | Local proton hopping mechanism in imidazolium-based plastic crystal:an ab initio molecular dynamics study显示文摘Protic organic ionic plastic crystals(POIPCs)are promising solid-state proton conductor materials in anhydrous proton exchange membrane fuel cells,due to their mechanical flexibility and high ionic conductivity in the plastic crystal phase.In typical POIPCs,the ions are orientationally disordered while the centers of mass are ordered(positional order)like the crystal phase.The local disorder provides more degrees of freedom for the translational and rotational diffusion of ions,thus enhancing proton conduction either via the vehicle mechanism or the Grotthuss mechanism.Yet the local dynamics and the interactions of the cations and anions during the proton transfer process are far from being fully understood.Here,we performed Car–Parrinello molecular dynamics(CPMD)simulation on the imidazolium methanesulfate([ImH][CH_(3)SO_(3)])unit cell.By artificially creating one proton hole,we found that a proton can hop directly between the cations.Though the anion is not directly involved in proton hopping,the oxygen atom in the sulfonate group interacts with the proton and has a synergetic motion along with the proton hopping process.This indicates the structural disorder of imidazolium rings and the aid of an anion can facilitate Grotthuss-type proton hopping in imidazolium-based POIPCs. | Bohai Zhang Yike Huang Jiangshui Luo Ailin Li Tianying Yan | 2022 | Communications in Theoretical Physics2022，74，4： | 0 |
