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

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