| 1 | Unrevealing the effects of low temperature on cycling life of 21700-type cylindrical Li-ion batteries显示文摘The low-temperature performance of Li-ion batteries(LIBs) has important impacts on their commercial applications. Besides the metallic lithium deposition, which is regarded as one of the main failure mechanisms of the LIBs at low temperatures, the synergistic effects originating from the cathode, anode, electrolyte, and separators to the batteries are still not clear. Here, the 21700-type cylindrical batteries were evaluated at a wide range of temperatures to investigate the failure mechanism of batteries. Voltage relaxation, and the post-mortem analysis combined with the electrochemical tests, unravel that the capacity degradation of batteries at low temperature is related to the lithium plating at graphite anodes,the formation of unsatisfied solid deposited/decomposed electrolyte mixture phase on the anode, the precipitation of solvent in the electrolytes and the block of separator pores, and the uneven dissolved transition metal-ions from the cathode. We hope this finding may open up a new avenue to alleviate the capacity degradation of advanced LIBs at low temperatures and shed light on the development of outstanding low-temperature LIBs via simultaneous optimization of all the components including electrodes, electrolytes and separators. | Daozhong Hu Gang Chen Jun Tian Ning Li Lai Chen Yuefeng Su Tinglu Song Yun Lu Duanyun Cao Shi Chen Feng Wu | 2021 | Journal of Energy Chemistry2021，30，9： | 3 |

| 3 | Tailored Carrier Transport Path by Interpenetrating Networks in Cathode Composite for High Performance All‑Solid‑State Li‑SeS_(2) Batteries显示文摘All-solid-state Li-SeS_(2) batteries(ASSLSs)are more attractive than traditional liquid Li-ion batteries due to superior thermal stability and higher energy density.However,various factors limit the practical application of all-solid-state Li-SeS_(2) batteries,such as the low ionic conductivity of the solid-state electrolyte and the poor kinetic property of the cathode composite,resulting in unsatisfactory rate capability.Here,we employed a traditional ball milling method to design a Li_(7)P_(2.9)W_(0.05)S_(10.85) glass–ceramic electrolyte with high conductivity of 2.0 mS cm^(−1) at room temperature.In order to improve the kinetic property,an interpenetrating network strategy is proposed for rational cathode composite design.Signifcantly,the disordered cathode composite with an interpenetrating network could promote electronic and ionic conduction and intimate contacts between the electrolyte–electrode particles.Moreover,the tortuosity factor of the carrier transport channel is considerably reduced in electrode architectures,leading to superior kinetic performance.Thus,assembled ASSLS exhibited higher capacity and better rate capability than its counterpart.This work demonstrates that an interpenetrating network is essential for improving carrier transport in cathode composite for high rate all-solid-state Li-SeS_(2) batteries. | Lei Zhou Muhammad Khurram Tufail Yaozu Liao Niaz Ahmad Peiwen Yu Tinglu Song Renjie Chen Wen Yang | 2022 | Advanced Fiber Materials2022，4，3： | 1 |

| 5 | Stable cycling of LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2)/lithium metal batteries enabled by synergistic tuning the surface stability of cathode/anode显示文摘Ni-rich layered oxides(LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2))show great potential in long-range and low-cost lithiumion batteries.However,due to the high surface sensitivity,their practical application is hindered by interfacial instability with electrolytes under high voltage for long cyclic life.Herein,by combining both firstprinciple calculations and time-of-flight secondary ion mass spectrometry(TOF-SIMS),a novel surface fluorinated reconstruction(SFR)mechanism is proposed to improve the interfacial stability under high voltage,which could effectively regulate the surface fluoride species to desensitize the LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2)interface.We demonstrate here that by tuning the ratio of fluoride species,the LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2)/Li battery could achieve excellent long-term and high voltage performance(163.5 mA h g^(-1)at 0.5 C for 300 cycles under 4.4 V),while the controlled sample decayed to 125.4 mA h g^(-1)after 300 cycles.Moreover,the favorable cross-talk effect induced by SFR further facilitates the incorporation of suitable amounts of Ni ions into the construction of stable solid electrolyte interface(SEI)layer for anode surface.Therefore,the ultra-long cycling stability under high voltage can be achieved by the robust cathode/electrolyte and Li/electrolyte interfaces,which results in excellent interfacial stability after long cycling.This work provides new insights into the surface design of cathode materials and improves the stability of the electrode-electrode interface under high voltage. | Chunli Li Xinyu Zhang Zhuolin Yang Haijian Lv Tinglu Song Shijie Lu Yuxiang Zhang Tianwen Yang Fan Xu Feng Wu Daobin Mu | 2023 | Journal of Energy Chemistry2023，，12： | 0 |
| 6 | Surface engineering of 1D nanocatalysts for value-added selective electrooxidation of organic chemicals显示文摘Electrolytic water splitting by renewable energy is a technology with great potential for producing hydrogen(H_(2))without carbon emission,but this technical route is hindered by its huge energy(electricity)cost,which is mainly wasted by the anode oxygen evolution reaction(OER)while the value of the anode product(oxygen)is very limited.Replacing the high-energy-cost OER with a selective organic compound electrooxidation carried out at a relatively lower potential can reduce the electricity cost while producing value-added chemicals.Currently,H_(2) generation coupled with synthesis of value-added organic compounds faces the challenge of low selectivity and slow generation rate of the anodic products.One-dimensional(1D)nanocatalysts with a unique morphology,well-defined active sites,and good electron conductivity have shown excellent performance in many electrocatalytic reactions.The rational design and regulation of 1D nanocatalysts through surface engineering can optimize the adsorption energy of intermediate molecules and improve the selectivity of organic electrooxidation reactions.Herein,we summarized the recent research progress of 1D nanocatalysts applied in different organic electrooxidation reactions and introduced several different fabrication strategies for surface engineering of 1D nanocatalysts.Then,we focused on the relationship between surface engineering and the selectivity of organic electrooxidation reaction products.Finally,future challenges and development prospects of 1D nanocatalysts in the coupled system consisting of organic electrooxidation and hydrogen evolution reactions are briefly outlined. | Yongping Yang Chuhao Liu Tinglu Song Mufan Li Zipeng Zhao | 2024 | Nano Research2024，17，3： | 0 |
| 7 | Vacancy healing for stable perovskite solar cells via bifunctional potassium tartrate显示文摘Perovskite solar cell has gained widespread attention as a promising technology for renewable energy.However, their commercial viability has been hampered by their long-term stability and potential Pb leakage. Herein, we demonstrate a bifunctional passivator of the potassium tartrate(PT) to address both challenges. PT minimizes the Pb leakage in perovskites and also heals cationic vacancy defects, resulting in improved device performance and stability. Benefiting from PT modification, the power conversion efficiency(PCE) is improved to 23.26% and the Pb leakage in unencapsulated films is significantly reduced to 9.79 ppm. Furthermore, the corresponding device exhibits no significant decay in PCE after tracking at the maximum power point(MPP) for 2000 h under illumination(LED source, 100 mW cm^(-2)). | Jing Dou Yue Ma Xiuxiu Niu Wentao Zhou Xueyuan Wei Jie Dou Zhenhua Cui Qizhen Song Tinglu Song Huanping Zhou Cheng Zhu Yang Bai Qi Chen | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
