Apparatus and method of manufacturing a battery cell

摘要

A battery cell manufacturing apparatus comprises a vacuum indexing conveyor for vertically suspending an anode material web, wherein a die punch is used to form a discrete anode from the anode material web. A pick and place mechanism is operable with the die punch for positioning the discrete anode between first and second separator webs for subsequent lamination. A laminator vertically receives the separator webs suspended for longitudinally extending them a force of gravity for smoothing out web surfaces adjacent the discrete anode carried therebetween prior to lamination of the separator webs to the discrete anode. A cathode assembly section includes a vacuum conveyor for guiding cathode material webs and vertically suspending them for die punching discrete cathodes which are then placed onto exposed outside surfaces of the vertically suspended separator webs in alignment with the anode laminated therewith. The discrete cathodes are then laminated to the vertically suspended separator webs for forming a laminated battery cell, which webs are then cut to form a discrete battery cell.
