We’re introducing novelty for prismatic Li Ion Cells where many don’t look and we’re doing it with evidence: In prismatic cells, the cell envelope of the electrode stack is often treated as “just packaging.” We see it differently. Leakage current is a fast way to uncover localized insulation vulnerabilities — if your measurement is sensitive, it provides confidence into the insulation material. This test snapshot illustrates how we validate electrical stability under defined compression of our nonwoven Battery Cell Envelope material. Picoampere sensitivity is used to capture early signals. Why it matters: validated, robust electrical insulation for demanding battery applications beyond PowerPoint. Download information regarding our Nonwoven Battery Cell Envelopes, at https://on.fst.com/42iVv9p This May, we've been sharing a short, data-backed video series showing how nonwoven battery cell envelopes can be a credible alternative to standard PP film and how we validate that credibility with testing, not assumptions. Get ready for the final video packed with data and insights on June 2.
