$MULN Lithium-Sulfur batteries use the same manufacturing equipment as Lithium-Ion, but with simpler steps and a smaller factory footprint, meaning less than half the cost to manufacture.
Mullen is committed to reducing greenhouse gas emissions in every aspect of its business. This includes the use of low carbon footprint materials and emerging technologies, in this case, readily available Sulfur made from by-products of recycling oil refinement instead of heavily mined rare earth metals.
The water-based cathode means no rare metals are used. The Sulfur utilized is sustainably sourced, fully recyclable, ubiquitously available, and inexpensive. https://www.mullenusa.com/battery
