GM GM to Build EV Battery Separator Plant in the U.S. |



Separators play a crucial role in the process of battery recycling and is a critical component of the energy storage system.


To meet the increasing need for electric vehicles, GM has invested in growing its EV battery business with the opening of new facilities, including an EV battery separator. A partnership between General Motors and battery manufacturer MicroVast aims to develop and build a new separator plant in the U.S. The project will focus on reducing the number of components inside a battery pack, as well as low-cost methods of manufacturing the separator.

Electric vehicle batteries are complex and require the use of separators to separate the anode and cathode. Their function is vital in ensuring that the battery will continue to function correctly and safely if a support cable snaps or if there is an internal fault in the battery.

In order to achieve the goal of improving the thermal stability of EV batteries, the two companies will work together to develop new separator technology and incorporate advanced materials and processes into the separator design. A $200 million grant from the U.S. Department of Energy's Battery Materials Processing and Battery Manufacturing initiative will support a battery separator plant in the United States. The purpose of this initiative is to increase the capacity of manufacturing facilities that produce batteries and battery components, thereby making it easier for companies to produce more electric vehicles.

"This collaboration with Microvast supports our ongoing efforts to develop a North American-focused EV supply chain and help put everyone in an EV,". "It will also provide us with pioneering separator technology that can be used in future Ultium batteries, and most importantly, supports our continuing commitment to safety." GM chief technology officer and vice president of Research and Development, Kent Helfrich, stated. [1]

GM has been investing heavily in electric vehicle technology as part of its strategy to remain at the forefront of this rapidly evolving industry. With U.S. consumers becoming more interested in alternative fuel sources, battery-powered vehicles should see increasing demand in the coming years.
