Report by Xiong Wen (David) LOU from Nanyang Technological University

摘要(Teaser): 

Dr. David Lou X.W. , from  Nanyang Technological University, give us a talk this Saturday. This talk is mainly about "Synthesis of Nanostructured Metal Oxide Materials and Their Application in Li-ion Batteries".

Observing a single Li-ion-column at atomic resolution using aberration-corrected annular-bright-field microscopy

摘要(Teaser): 

Recently, Prof. Lin Gu, Prof. Xiaofeng Duan and Dr. Xiaoqing He at the Beijing National Laboratory for Condensed Matter Physics, The Institute of Physics, Chinese Academy of Sciences (IOP, CAS) in close collaboration with Prof. Hong Li, Prof. Yong-Sheng Hu and Prof. Liquan Chen (IOP, CAS), together with scientists from the Max Plank Institute for Solid State Research, Japan Fine Ceramic Center and The University of Tokyo, have developed an annular-bright-field scanning transmission electron microscopy, which can image lithium atoms directly in cathode materials e.g. LiFePO4 (http://pubs.acs.org/doi/abs/10.1021/ja109412x). Corresponding relationship between experimental parameters and image contrast was also discussed systematically (Mater. Express 1, 43-50, 2011). 

Li4Ti5O12 coated by nitrogen-doped carbon for long life stationary Li ion batteries

摘要(Teaser): 

Recently, PhD student Liang Zhao and Prof. Yong-Sheng Hu et al. in Group E01 from the Institute of Physics, CAS/Beijing National Laboratory for Condensed Matter Physics proposed a new carbon-coating technique for electrode materials using nitrogen-containing ionic liquids (ILs) as precursor. The porous Li4Ti5O12 uniformly coated with 1-2nm thickness of nitrogen-doped carbon shows excellent cycling performance (with a capacity retention of 83% after 2200 cycles in a half cell) and high rate capability (129 mAh/g at 10C discharge/charge rate with a capacity retention of 80%, 10C means full charge/discharge in 6 min).
