Particulate-reinforced Al-based composite material for anode in lithium secondary batteries

Particulate-reinforced Al/SiC composite materials are prepared by ball-milling technique to be used as an anode material for lithium secondary battery. The microstructure of the composite powders show that the SiC particles are embedded homogeneously in the Al matrix. This feature is distinctively different from any other active/inactive composite anode materials reported recently. The cycle performance of these composite electrodes is superior to that of an unreinforced aluminium electrode. This improved cycelability may be due to an enhanced mechanical stability of the electrode. (C) 2001 Elsevier Science B.V. All rights reserved.
