题目：Recent Advances in Metal Oxide-based Electrode Architecture Design for Electrochemical Energy Storage
依托金属氧化物，通过电极结构的设计来提高电化学性能
摘要：Metal oxide nanostructures are promising electrode materials for lithiumion batteries and supercapacitors because of their high specifi c capacity/capacitance, typically 2–3 times higher than that of the carbon/graphitebased materials. However, their cycling stability and rate performance still can not meet the requirements of practical applications. It is therefore urgent to improve their overall device performance, which depends on not only the development of advanced electrode materials but also in a large part “how to design superior electrode architectures”. In the article, we will review recent advances in strategies for advanced metal oxide-based hybrid nanostructure design, with the focus on the binder-free fi lm/array electrodes. These binderfree electrodes, with the integration of unique merits of each component, can provide larger electrochemically active surface area, faster electron transport and superior ion diffusion, thus leading to substantially improved cycling and rate performance. Several recently emerged concepts of using ordered nanostructure arrays, synergetic core-shell structures, nanostructured current collectors, and fl exible paper/textile electrodes will be highlighted, pointing out advantages and challenges where appropriate. Some future electrode design trends and directions are also discussed.[ Last edited by shenao on 2012-8-22 at 12:27 ]
