ABSTRACT:
A process for applying a graphite coating to the interior of a prismatic battery can by filling the can with a slurry containing graphite particles, immediately removing the slurry with an aspirating nozzle and then drying the residue left in the battery can to leave a thin film of graphite on the interior of the can. In a continuous process, fill nozzles and aspirating nozzles are moved in set into and out of the cans simultaneously, while moving the nozzles along with the cans through a fill and aspirate station on a conveyor. From there the cans travel through a drying oven where the residue remaining in the cans is dried to leave a thin uniform graphite film inside a prismatic can.
