At Valgotech’s Energy Research and Development (VERAD) Center in Indiana, one of the key products we are developing is practical lithium sulfur (Li-S) batteries. Valgotech’s batteries are made of sustainable sulfur-carbon cathode materials that provide superior benefits to customers:
Valgotech’s proprietary battery materials (separator and cathode) and unique cell designs prevent thermal runaway (fire) common with lithium-ion batteries. Li-S batteries also have theoretical energy density that exceeds 10 times that of lithium-ion cathode materials, making them lighter weight. Sulfur is also abundantly and cheaply available, resulting in a lower cost battery system. Our goal is to jumpstart local battery cells manufacturing by removing the supply chain challenges associated with foreign-sourced lithium-ion cathode materials like cobalt and manganese.
