“…Recently, Sony has commercialised its Nexelion® range of Li-ion cells containing Sn-Co-C anodes. Such alloys have shown excellent cycling abilities attributed to the active-inactive relationship between Sn and Co [98][99][100][101]. Other alloys include Sn-Ni-C [102] and Sn-Cu [103] which also utilise the inactive metal and carbon as a structural buffer, thus alleviating much of the alloyed-induced strain.…”

Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.

“…In addition, nanowires form direct chemical bonds with the current collector for good adhesion and electron transport, which makes the binding polymer and conducting graphite unnecessary. The observed specific capacity was about 2800 Ah Kg 1 [84]. Yushin et al conducted a large-scale hierarchical bottom-up assembly route for the formation of Si on the nanoscalecontaining rigid and robust spheres with irregular channels for rapid access of Li ions into the particle bulk.…”

Compared to other types of rechargeable batteries, the rechargeable lithium battery has many advantages, such as: higher energy density, lower self-discharge rate, higher voltages and longer cycle life. This article provides an overview of the cathode, anode, electrolyte and separator materials used in rechargeable lithium batteries. The advantages and challenges of various materials used in rechargeable lithium batteries will be discussed, followed by a highlight of developing trends in lithium battery research.

“…Different metals have been considered including Cu [37], Ni [38][39][40], Co [41,42], Fe [43][44][45] or Nb [46]. The case of Co is of particular interest and Sony commercialized in 2005 the Nexelion battery with a Co-Sn-C amorphous anode improving the capacity of the battery by 30% compared to other systems [47][48][49][50][51]. However, the replacement of Co by another metal such Fe might reduce the cost of the electrode materials and improve the environmental impact [52].…”

“…However, a capacity fading generally occurs after 50 cycles because of the loss of electrical contacts during the charge-discharge cycles and the growth/coalescence of the particles, as shown by in situ Mössbauer experiments [45]. The capacity fading is observed for all the tin based intermetallics although it can be reduced by optimizing the electrode formulation or the material composition [48,57,58]. Although the reaction mechanisms are similar for the other transition metals, back reactions of tin with the metallic nanoparticles were often observed by Mössbauer spectroscopy during the charge.…”

In the domain of Li-ion batteries, Mössbauer spectroscopy is mainly used for the characterization of electrode materials and the analysis of electrochemical reactions. Depending on the properties under investigation, different approaches are often considered, which are based on ex situ, in situ and operando measurements. The specific electrochemical cells and sample preparations used for such measurements are described in this paper. Applications to selected examples of cathode and anode materials are presented in order to show how Mössbauer spectroscopy, when associated with other techniques, provides essential information to understand the mechanisms and improves the performances of Li-ion batteries.
