Abstract
Electrical de conductance of a composite electrode for a lithium-ion batter y was monitored in situ during successive charge/discharge cycles, in order to investigate functions of conductive additives. Such measurement was ach ieved by means of an interdigitated microarray electrode with a bipotentios tat. The composite films of mesocarbon microbeads ( MCMBs) heat-treated at 1000 degrees C were studied with conductive additives of acetylene black or a synthetic graphite in a 1 M LiClO4, non-aqueous carbonate solution. The role of the conductive additives is discussed in connection with their type and content within the composites. In addition, we propose a modified prep aration procedure for the composites having a high retention of conductance . (C) 1999 Elsevier Science S.A. All rights reserved.
