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\u2019s simple: Add NeoGraf Solutions\u2019 SpreaderShield\u2122 thin, flexible, and lightweight graphite heat spreader to the battery pack. [...]\r\nLearn More<\/a><\/span><\/p><\/div><\/article>

In many early battery-powered electric vehicles, cell temperatures were controlled by aluminum. It was a time-tested thermal management material and it could take on some of the structural duties of the \r\nbattery pack. Battery pack designers recognized aluminum\u2019s drawbacks and began looking for alternative thermal management materials. To spread the same amount of heat as an aluminum plate, NeoGraf \r\nSolutions\u2019 SpreaderShield\u2122 flexible graphite is only half of the thickness and one-third of the weight.

In order for battery powered transportation to become fully viable in the near future, energy density of the battery pack must increase. The optimal solution is to use large surface area pouch \r\ncell batteries packed tightly together to form highly energy dense modules. NeoGraf Solutions\u2019 has produced a new video that shows unique an-isotropic arrangement of the high conductivity graphene \r\nlayers in their SpreaderShield\u2122 graphite. It illustrates how the material prevents battery hot spots, maintaining allowable temperatures and restricts transferring the heat to adjacent battery cells with the \r\nthinnest and lightest form-factor possible.

When it comes to safety in an Electric Vehicle (EV), the most important aspect is controlling the massive amount of energy stored in the battery pack. To help with this, significant advances have been made in cell design and battery management systems (BMS). However, even with these advances, the possibility of a single-cell failure is always present. SpreaderShield\u2122 flexible graphite heat spreaders are often used as the thermal management material in high-performance battery packs where a small and lightweight form factor is desirable.
