Title:
PROCESS FOR APPLYING GRAPHITE COATINGS TO NON-CYLINDRICAL BATTERY CANS
Document Type and Number:
WIPO Patent Application WO2005060022
Kind Code:
A3
Abstract:
A process for applying a graphite coating to the interior of a prismatic battery can (10) by filling the can with a slurry (24) containing graphite particles, immediately removing the slurry with an aspirating nozzle (26) 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 sets 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.
