Gas Diffusion Membranes
Strongest, most balanced hydrophobic membranes
Engineered to improve battery performance and life
GORE™ polytetrafluoroethylene (PTFE) membranes (formerly EXCELLERATOR®) ensure consistent long battery life through precise, controlled gas diffusion and reliable electrolyte containment.
 |
New, ultra-thin, high-strength membranes take up less space in the cell, allowing batteries that are smaller and lighter, or that extend battery life without increasing size or weight. The high strength of these membranes allow them to withstand extreme manufacturing stresses and resist splitting if the battery swells due to absorbed moisture or dimensional change.
