At NexTech Batteries, we pursue the development of next-generation lithium batteries (beyond lithium-ion) with unparalleled safety, energy density, low cost, ethical supply chain, and environmental stewardship for global vehicle electrification, consumer electronics, renewable energy storage, and more.


NexTech Batteries was founded in early 2016 and was the result of the company’s founders securing exclusive license rights and patents to Lithium Sulfur Battery Technology developed at Lawrence Berkeley National Laboratory. This powerful and disruptive Li-S technology was the result of more than 14 years of research under the direction of Dr. Elton Cairns at LBNL. NexTech is one of the first entities to have recognized the long-term promise and scientific superiority surrounding lithium sulfur – and has since created patented processes and materials that deliver unparalleled battery power and performance that’s poised to evolve multiple global industries.
