Estimating the term…
In accordance with at least selected embodiments, aspects or objects, there are disclosed or provided new or improved pins adapted for use with high or higher COF polymer membranes or separator membranes (also known as sheets or films), polymer tension measuring, and/or related methods of use, of cell or battery manufacture, and/or the like. In certain embodiments, the new or improved pins are especially well suited for use with dry process polyolefin microporous membranes, separator membranes, or separators. In certain selected embodiments, the new or improved pins are especially well suited for use with dry process polyolefin microporous membranes, separator membranes, or separators in Z-fold or S-fold machines for the production of lithium ion pouch cells, lithium polymer pouch cells, lithium prismatic cells, and/or the like.
Pins, fingers or paddles adapted for use with dry process polyolefin microporous membranes, separator membranes, or separators in Z-fold or S-fold machines for the production of lithium ion pouch cells, lithium polymer pouch cells or lithium prismatic cells, comprising at least one curved surface, wherein at least a portion of the at least one curved surface is in contact with the dry process polyolefin microporous membrane, separator membrane, or separator in the Z-fold or S-fold machine.
Pins for use with high or higher COF polymer membranes or separator membranes, polymer tension measuring, and/or methods of cell or battery manufacture, comprising at least one curved surface, wherein at least a portion of the at least one curved surface is in contact with the polymer membrane or separator membrane.
