An emerging trend over the last two to three years has been to add layers of thermal insulation and flame/gas impingement barriers between the pouch and prismatic format cells in a battery pack to prevent thermal propagation. This passive thermal management solution has been shown to effectively prevent propagation without adding excessive weight to the battery. The obvious downside of this method is that the battery cells are surrounded by insulation, and there is no easy path for the internal heat of the cells to spread to the environment outside of the pack. How do you fix the problems caused by using an insulation-only strategy? It’s simple: Add NeoGraf Solutions’ SpreaderShield™ thin, flexible, and lightweight graphite heat spreader to the battery pack. [...] Learn More
