SMC Battery Enclosures

Sheet molding compound (SMC) material is a composite material made up of polyester resin, chemical agents, pigments, mineral fillers and reinforced by fiberglass. It has very good chemical resistant ability. It withstands most types of acid and alkali. Battery’s electrolyte is a typical erosive chemical. Many types of materials meet the requirement of chemical resistant, but why SMC material is such a best choice for making battery enclosure. There are many reasons besides chemical resistance. SMC is a very strong, rigid material. SMC enclosures can withstand the heavy batteries at a very low self-weight. This high strength-weight ratio increases the energy-weight ratio and reduces the total weight of battery packs which is very positive for electrical vehicle (EV) industries. Besides, SMC is fire resistant. It reaches V0 or 5VA (UL 94 standards) at a comparatively low cost. This increases safety rate of batteries. SMC is also very design-flexible. It can be molded into almost any shape of enclosures to suite the best usage of space when necessary.

That’s why SMC material is the best material for making battery enclosures.
