| 1 | Analysis and Discussion on Subway Construction Accidents from Geological Perspective显示文摘Several cave-in accidents often occur in subway construction,causing personnel and economic losses.This paper has carried on the statistics and analysis of some typical subway construction accidents in recent years.Taking the collapse accident of a subway station in Hangzhou as the engineering background,the causes of the collapse of the foundation pit were analyzed.The analysis found that groundwater,earthwork over-excavation,weak support design and inadequate monitoring are the main reasons.These factors should be highlighted in the construction of similar projects in the future to avoid similar tragedies. | Yuanjian Lin Jiangfeng Liu Ronghao Lv Chenyi Sun Zhendong Fan | 2019 | Journal of Geological Research2019，1，2： | 0 |
| 2 | A Li_(3)P nanoparticle dispersion strengthened ultrathin Li metal electrode for high energy density rechargeable batteries显示文摘Achievement of lithium(Li)metal anode with thin thickness(e.g.,≤30µm)is highly desirable for rechargeable high energy density batteries.However,the fabrication and application of such thin Li metal foil electrode remain challenging due to the poor mechanical processibility and inferior electrochemical performance of metallic Li.Here,mechanico-chemical synthesis of robust ultrathin Li/Li_(3)P(LLP)composite foils(~15µm)is demonstrated by employing repeated mechanical rolling/stacking operations using red P and metallic Li as raw materials.The in-situ formed Li+-conductive Li_(3)P nanoparticles in metallic Li matrix and their tight bonding strengthen the mechanical durability and enable the successful fabrication of free-standing ultrathin Li metal composite foil.Besides,it also reduces the electrochemical Li nucleation barrier and homogenizes Li plating/stripping behavior.When matching to high-voltage LiCoO_(2),the full cell with a low negative/positive(N/P)capacity ratio of~1.5 offers a high energy density of~522 W·h·kg^(-1) at 0.5 C based on the mass of cathode and anode.Taking into account its facile manufacturing,potentially low cost,and good electrochemical performance,we believe that such an ultrathin composite Li metal foil design with nanoparticle-dispersion-strengthened mechanism may boost the development of high energy density Li metal batteries. | Lin Fu Xiancheng Wang Bao Zhang Zihe Chen Yuanjian Li Yongming Sun | 2024 | Nano Research2024，17，5： | 0 |
| 3 | Insights on“nitrate salt”in lithium anode for stabilized solid electrolyte interphase显示文摘A Li/KNO_(3) composite(LKNO),with KNO_(3) uniformly implanted in bulk metallic Li,is fabricated for battery anode via a facile mechanical kneading approach,which exhibits high Coulombic efficiency and prolonged cycle life.The mechanism behind the enhanced electrochemical performance of the“salt-in-metal”composite is investigated,where KNO_(3) in metallic Li composite electrode would be sustainably released into the electrolyte.The presence of NO_(3)-stabilizes the solid electrolyte interphase by producing functional Li_(3)N,LiNxOy,and Li_(2)O species.K^(+)from KNO_(3) also helps to form an electrostatic shield after its adsorption on the electrode protrusions,which suppresses the dendritic growth of metallic Li.With the above advantages,uniform Li plating with dense and planar structure is realized for the LKNO electrode.These findings reveal a deep understanding of the effect of the“saltin-metal”anode and provide new insights into the use of nitrate additives for high-energy-density Li metal batteries. | Lin Fu Xiancheng Wang Zihe Chen Yuanjian Li Eryang Mao Zhi Wei Seh Yongming Sun | 2022 | Carbon Energy2022，4，1： | 0 |
