It will be concluded in this blog about the previous development of advanced materials for Lithium Batteries(LIBs). Among which most of the points are from a latest review paper "Function materials for rechargeable batteries, Adv. Mater, 2011, 23, 1695-1715". The schematic of previous study concerning electrode materials is showed below: From the side of Cathode materials, Lithium metal oxides are commonly used to act as the provider of Li-ion in the charging procedure. The potential capacity of this cathode materials is competitive but a poor ability of capacity retention remains a big problem. The polyanionic based materials are regarded as the next generation materials for Cathode due to its safety and reversibility of Lithium storage. This category could be represented by LiFePO4. Latest research indicates that the nanosize effect plays a great role in the contribution ofextremelyhigh performance, which would be a hot point in the future research. There are also organic materials which has also attracted a lot attentions, but will not described in details here. When comes to the materials for anode, lithium alloys (mainly with main-group elements)show great potential capacity due to its reaction with Lithium. However, the great volume expansion during the reactions could never be neglected. Hollow nanostructures could reduce the inner strain due to the volume variation. For instance, Ag coated 3D porous silicon has been developed to reduce the effect of volume expansion, which could be illustrated by the figure below: What's more, carbon coating of the tin based materials will decrease the volume expansion in a large extend.Another kind of anode materials—Transition metal oxides also attract similar considerations in a similar way. Such combination of two kinds of materials will take advantage of the characteristics of two or more kinds of materials, which represent the trend of developing novel anode materials.
This blog is about a short review of the current papers——carbon based materials for anode in Lithium-ion Batteries(LIB). Most of the contents are points from "A review of application of carbon nanotubes for lithium ion battery material, JPS, 2012, 74-85". The application mentioned in this paper is interesting and I'm happy to share this information to my friends. The great demand of high performance LIBs are in great need with the advent of plug-in hybrid vehicles. The schematic above illustrate the mechanism of working in a LIB, that is to say, materials of anode, cathode and the electrolyte will play a great role in the development of supper batteries. When put into practice, the capacity and life span are two characters which scientist care most about. Previously,LiM0x are used as the anode for its great theoretical capacities. However, there will also been a great expansion for the overall volume during the working cycle. Graphite was then chose as a better material due to its special layered structure. The insertion of Lithium ions in to the spacing of different layers will not cause a significant expansion of the overall voulme. However, six carbon atoms are needed to store one lithium ion, which induce a great lose of the theoretical capacity.Schematic of insertion mechanism of Lithium ions are illustrated below: In order to improve this situation, carbon nanotubes(CNTs) are introduced due to its special one-dimensional structure.Nevertheless, the research of CNTs for anodes are quite recent. There are drawbacks which could not be overcome currently. In the first place, the consumption of lithium ions could never be neglected, what's more, there is a lack of voltage plateau during the discharging procedure. Those are both morphology dependent factors, which is supposed to be solved by decorating metal nanoparticles and core-shell composite anodes. Problems might occur due to the controlling of defects when preparing and using. More discuss could be made concerning the formation and interaction of defects in this new generation of anode materials.
http://www.springerlink.com/content/a511055413620019/ Understanding the electrothermal-mechanical behavior of electronic interconnects is of practical importance in improving the structural reliability of electronic devices. In this work, we use the finite-element method to analyze the Joule-heating-induced thermomechanical deformation of a metallic sphere that is sandwiched between two rigid plates. The deformation behavior of the sphere is elastic–perfectly plastic with Young’s modulus and yield stress decreasing with temperature. The mechanical stresses created by Joule heating are found to depend on the thermal and mechanical contact conditions between the sphere and the plates. The temperature rise in the sphere for the diathermal condition between the sphere and the plates deviates from the square relation between Joule heat and electric current, due to the temperature dependence of the electrothermal properties of the material. For large electric currents, the simulations reveal the decrease of von Mises stress near the contact interfaces, which suggests that current-induced structural damage will likely occur near the contact interfaces.

Yu a a Advanced Manufacturing Technology Research Centre, Department of Industrial and Systems Engineering, The Hong Kong Polytechnic University, Hong Kong b State Key Laboratory of Material Processing and Die Mould Technology, Huazhong University of Science and Technology, 430074 Wuhan, People's Republic of China Received 18 November 2010; accepted 14 January 2011. Available online 25 January 2011. Abstract In this paper, the effect of nickel coating on the plasticity of a brittle Fe-based bulk metallic glass (BMG) was investigated. By electrodepositing a nickel coating onto an Fe 75 Mo 5 P 10 C 8.3 B 1.7 BMG, the plasticity of the BMG is shown to increase dramatically from ~ 0.5% to ~ 5.0%. Without reducing the strength of the BMG, the findings demonstrate that the electrodeposited nickel is an effective way to improve prominently brittle BMGs. The increased compressive plastic strain is believed to be attributed to the nucleation, intersection and bifurcation of multiple shear bands due to the exterior impedance of the surrounding coating.

In particular, the demonstration of light-emitting diodes and photodetectors on flexible electronic substrates now opens the door to applications of flexible optoelectronic sheets in biomedicine and robotics. Abstract: http://links.ealert.nature.com/ctt?kn=75m=35910058r=NDU1MzI2NDEzOAS2b=2j=ODQ3ODM5NTIS1mt=1rt=0 Article: http://links.ealert.nature.com/ctt?kn=103m=35910058r=NDU1MzI2NDEzOAS2b=2j=ODQ3ODM5NTIS1mt=1rt=0 Observation of long-range exciton diffusion in highly ordered organic semiconductors pp938 - 943 H. Najafov et al. doi:10.1038/nmat2872 Excitons in polycrystalline films of organic semiconductors typically migrate distances of the order of tens of nanometres. Photoconductivity measurements in highly ordered rubrene now show that exciton diffusion can reach the micrometre range, opening a route to designing excitonic circuitry for applications in photocatalysis, photochemical sensing or photovoltaic energy conversion.

Ambient-pressure X-ray photoelectron spectroscopy on single-chamber cells now suggests that surface reaction kinetics and electron transport on the electrodes are co-limiting processes.
