Abstract
Cathodes for aluminum electrolysis cells are formed of cathode blocks and current collector bars attached to those blocks. The cathode slots receiving the collector bar are lined with expanded graphite lining thus providing longer useful lifetime of such cathodes and increased cell productivity. The expanded graphite provides a good electrical and thermal conductivity especially with its plane layer.
