Li-ion batteries perform best when maintained within an optimal temperature range. The challenge is exacerbated by the consumer''s desire for a rapid charge and discharge, both of which add to heat management issues. Too hot or too cold and thermal instability can occur leading to thermal runaway that can at best destroy the cell and at worst start a vehicle fire.
Advanced batteries and emerging battery technologies are thoroughly surveyed and discussed. NCM622 (Li[Ni 0.6 Co 0.2 Mn 0.2]O 2) and NCM811 can be considered as state-of-the-art materials for automotive applications, while the anode is still dominated by graphite and only a few cells apply silicon (in form of SiO x) in small amounts (≤ 8 wt%).
Despite a lower fire occurrence rate than combustion vehicles, fire safety is critical for electric vehicles and presents several material opportunities. This report considers the regulation and battery design trends and how this will impact fire protection materials such as ceramics, mica, aerogels, coatings, encapsulants, foams, compression pads, phase change materials, and

It's hard to imagine a car without plastics. The same is true for batteries - not only as energy storage devices, but also due to their handling, safety and general function. In this context, choosing the right plastic for the specific application is crucial for the reliability and safety of the battery.
Today, we present the 7 most common polymers, their specific applications and advantages in battery applications. PP is commonly used in battery cases due to its light weight and resistance to acids and alkalis. In much smaller quantities, it is used as a separator in film forms.
One plug-in hybrid EV built in China is already using a thermoplastic polypropylene compound instead of aluminium for its battery case cover, providing savings in weight. Other EVs now in production around world are using several thermoplastic materials for components such as cell carriers and housings, battery modules and battery enclosures.
One perception is that plastics are not suitable for battery packs as they cannot prevent thermal runaway and fires. However in testing, an aluminium plate was exposed for 5 minutes to a flame with a temperature of 1100 ºC. The same test on a plate made from long glass fibre polypropylene and a flame retardant (FR) resin reacted very differently.
