| 1 | Recent progress of advanced anode materials of lithium-ion batteries显示文摘The rapid development of electric vehicles and mobile electronic devices is the main driving force to improve advanced high-performance lithium ion batteries(LIBs).The capacity,rate performance and cycle stability of LIBs rely directly on the electrode materials.As far as the development of the advanced LIBs electrode is concerned,the improvement of anode materials is more urgent than the cathode materials.Industrial production of anode materials superior to commercial graphite still faces some challenges.This review sets out the most basic LIBs anode material design.The reaction principles and structural design of carbon materials,various transition metal oxides,silicon and germanium are summarized,and then the progress of other anode materials are analyzed.Due to the rapid development of metal organic frameworks(MOFs)in energy storage and conversion in recent years,the synthesis process and energy storage mechanism of nanostructures derived from MOF precursors are also discussed.From the perspective of novel structural design,the progress of various MOFs-derived materials for alleviating the volume expansion of anode materials is discussed.Finally,challenges for the future development of advanced anode materials for LIBs will be considered. | Hui Cheng Joseph G.Shapter Yongying Li Guo Gao | 2021 | Journal of Energy Chemistry2021，30，6： | 10 |
| 2 | Recent progress in sulfur cathodes for application to lithium-sulfur batteries显示文摘Owing to the extensive use of fossil fuels for energy,environmental problems are becoming increasingly severe.Therefore,renewable clean energy sources must be urgently developed.As an environmentally friendly electrochemical energy-storage system,lithium-ion batteries(LIBs)are widely used in portable devices,electric vehicles,and medical equipment.However,owing to their high cost and low theoretical energy density,LIBs are far from meeting the current energy demand.Lithium-sulfur batteries(LSBs)(wherein lithium metal and sulfur are the anode and cathode,respectively)are one of the most valuable secondary batteries because of their high theoretical energy density(-2600Whkg^(-1)).However,the intrinsic conductivity of sulfur cathode materials is poor,and the lithium polysulfide formed during lithiation dissolves easily.Moreover,the volumetric expansion during charging and discharging adversely affects the LSB electrochemical performance,including the rate performance,cycle life,and coulombic efficiency.Therefore,to improve the LSB electrochemical performance,various sulfur composites have been prepared using carbon materials,metallic oxides,and conductive polymers,and various composite cathode materials recently developed for application to LSBs were reviewed.Finally,research directions were proposed for modifying LSB cathode materials. | Yongying Li Joseph G.Shapter Hui Cheng Guiying Xu Guo Gao | 2021 | Particuology2021，19，5： | 0 |
| 3 | Pyramid-Textured Antireflective Silicon Surface In Graphene Oxide/Single-Wall Carbon Nanotube–Silicon Heterojunction Solar Cells显示文摘Antireflection layers are commonly used in photovoltaics to increase light absorption and therefore increase maximum photocurrent.Here,pyramid structures are created on Si surfaces with alkaline solution etching.The extent of pyramid coverage depends directly on the reaction time and as a result,the surface reflectance decreases with reaction time. | LePing Yu Munkhbayar Batmunkh Mahnaz Dadkhah Cameron J.Shearer Joseph G.Shapter | 2018 | Energy & Environmental Materials2018，1，4： | 0 |
| 4 | Poly(thiourea triethylene glycol) as a multifunctional binder for enhanced performance in lithium-sulfur batteries显示文摘A mechanically strong binder with polar functional groups could overcome the dilemma of the large volume change during charge/discharge processes and poor cyclability of lithium-sulfur batteries(LSBs).In this work,for the first time,we report the use of poly(thiourea triethylene glycol)(PTTG)as a multifunctional binder for sulfur cathodes to enhance the performance of LSBs.As expected,the PTTG binder facilitates the high performance and stability delivered by the Sulfur-PTTG cathode,including a higher reversible capacity of 825 mAh g^(-1) at 0.2 C after 80 cycles,a lower capacity fading(0.123%per cycle)over 350 cycles at 0.5 C,a higher areal capacity of 2.5 mAh cm^(-2) at 0.25 mA cm^(-2),and better rate capability of 587 mAh g^(-1) at 2 C.Such superior electrochemical performances could be attributed to PTTG's strong chemical adsorption towards polysulfides which may avoid the lithium polysulfide shuttle effect and excellent mechanical characteristics which prevents electrode collapse during cycling and allows the Sulfur-PTTG electrode to maintain robust electron and ion migration pathways for accelerated redox reaction kinetics. | Luke Hencz Hao Chen Zhenzhen Wu Xingxing Gu Meng Li Yuhui Tian Su Chen Cheng Yan Abdulaziz S.R.Bati Joseph G.Shapter Milton Kiefel Dong-Sheng Li Shanqing Zhang | 2022 | Green Energy & Environment2022，7，6： | 0 |
