“…Therefore, the TiO 2 -coated CMS shows quite stable cycleability. This action of TiO 2 is similar to that of Cu coating [27]. Together with the results of TiO 2 and Cu coating, it could be concluded that the cycleability of graphite will be improved by inert materials coating.…”

With the increasing importance of wireless microelectronic devices the need for on-board power supplies is evidently also increasing. Possible candidates for microenergy storage devices are planar all-solid-state Li-ion microbatteries, which are currently under development by several start-up companies. However, to increase the energy density of these microbatteries further and to ensure a high power delivery, three-dimensional (3D) designs are essential. Therefore, several concepts have been proposed for the design of 3D microbatteries and these are reviewed. In addition, an overview is given of the various electrode and electrolyte materials that are suitable for 3D all-solidstate microbatteries. Furthermore, methods are presented to produce fi lms of these materials on a nano-and microscale.www.MaterialsViews.com REVIEW www.advenergymat.de

“…Surface modification of graphite electrodes by deposition or coating with metal or metal oxide layers has been the subject of several papers [1][2][3][4][5][6][7][8][9][10][11][12][13]. In general, the presence of a metal layer or metal particles at the graphite surface leads to a substantial decrease in the charge transfer and solid electrolyte interface (SEI) resistances and to an effective protection against solvent co-intercalation permitting the use of propylene carbonate (PC)-based solvents.…”

Copper-coated graphite electrodes have been prepared by physical vapour deposition (PVD) and characterised as anodes for Li-ion batteries. The interfacial properties of the electrodes coated with copper layers of different thicknesses have been studied using impedance spectroscopy and com- pared with those of unmodified electrodes. A general enhancement of the performances of the coated electrodes in terms of decreased solid electrolyte interface (SEI) and charge transfer resistances has been found. The charge trans- fer resistance decreases at any intercalation potential for metal layer thickness of the order of 250–300 Å to increase again for thicker deposits. While in general the decrease in the charge transfer resistance may be related to a sort of cata- lytic effect of the metal layer in increasing the lithium deso- lvation rate, it is apparent that above a certain critical thick- ness value the layer acts as a barrier to the lithium ion transfer at the interface
