One of my customer based in the U.S.A claimed that one of our li-ion polymer cells tested by them can't meet the clause 5.2.3 of IEEE 1725 which depicts that the negative eletrode shall be at least 0.1 mm wider than the positive electrode on top and bottom the cell. Top management of our company takes the customer seriously. I'm desperate for the standard for referrence. Maybe we would take third party test into consideration.
