Some theoretical prerequisites for application of modified and expanded graphites, Si- and Sn-based composites and alloys, electroconducting polymers as active materials, catalysts and electro-conductive additives for lithium - ion batteries, metal-air batteries and electrochemical capacitors are considered. The models and the main concepts of battery-related use for such materials are proposed. [Pg.311]

The specific capacity obtained in such Ams, actually corresponds to near theoretical limit of 372 mA-h/g, as calculated on a basis of classical LiC6 stoichiometry). Further increase of capacity is possible only via switching to new or modified materials, composites or alloys, which are capable for reversible and stable intercalation of lithium. [Pg.313]

Other common anode materials for thermal batteries are lithium alloys, such as Li/Al and Li/B, lithium metal in a porous nickel or iron matrix, magnesium and calcium. Alternative cathode constituents include CaCr04 and the oxides of copper, iron or vanadium. Other electrolytes used are binary KBr-LiBr mixtures, ternary LiF-LiCl-LiBr mixtures and, more generally, all lithium halide systems, which are used particularly to prevent electrolyte composition changes and freezing out at high rates when lithium-based anodes are employed. [Pg.304]

A renewed interest in noncarbonaceous lithium alloy electrodes arose recently as the result of the announcement by Fuji Photo Film Co. of the development of a new generation of lithium batteries based upon the use of an amorphous tin-based composite oxide in the negative electrode [13]. It is claimed that these electrodes have a volumetric capacity of 3200, AhL" which is four times that commonly achieved with carbonaceous negative electrodes, and a specific capacity of 800, mAhg" twice that generally found in carbon-containing negative electrodes. [Pg.362]
