M. Nishizawa et al., In situ conductance measurement to investigate roles of conductive additives in lithium ion battery electrodes, ELECTROCH C, 1(9), 1999, pp. 375-378
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
