Top Battery Enclosure Manufacturers and Suppliers
Types of Battery Enclosure Suppliers
Thermal Management Materials and Products for Lithium Ion
Lithium ion batteries are widely adopted and will remain a popular energy storage option because of their high energy density and life cycle durability. However, the most common lithium ion makeup, lithium-cobalt-oxide, poses a fire hazard because it contains a flammable electrode and a reactive substance under pressure. Battery enclosure manufacturers are developing innovative materials to reduce fire hazard while maintaining low battery weights. To meet this need, several global companies manufacture advanced insulating and heat management materials. These materials include carbon fiber and proprietary polymers. Suppliers of these materials include both startups and large conglomerates that acquire startups for the value of their technology.
US Battery Enclosure Suppliers
These companies sell fabricated enclosures to house batteries for consumer electronics, military, electric utility, industrial, household, retail, hospital, marine, and campus applications. They sell aluminum and polymer battery enclosures, or cabinets, to protect batteries from heat and humidity.
In addition to evaluating the top companies in both of these categories, we have also compiled a list of the top suppliers of the more specific field of battery cooling enclosures. These are an important type of enclosure, since they help to prevent heat damage.
Battery Cooling Enclosure Suppliers
Battery cooling enclosures are a more specific type of enclosure that helps to protect batteries from heat stress and damage. Cooling enclosures come as either active systems, where a power-driven fan or air conditioner is used, or passive systems, which rely on the use of vents. In Table 1 below, we’ve ranked the top five US battery cooling enclosure suppliers in descending estimates of annual sales.
