Latest Patents
Freeman's latest patents focus on a method of compacting material, specifically cathode material for electrochemical cells. This method involves inserting a mixture into a die cavity, where it is compacted into a disk shape. The process utilizes a first plunger that presses down on the material and a second plunger that presses upwardly. To prevent flashing of material during the ejection of the disk from the die, a polymeric sleeve is fitted around the outer surface of the first plunger. This sleeve flexes to bulge outwardly, ensuring it does not enter the die cavity during compaction. It returns to its original position during the ejection of the compacted disk, preventing any material flashing. Alternatively, a polymeric seal ring can be placed around the first plunger, which also helps in preventing flashing during ejection.
