About SEI.

We are committed to helping save the world from climate chaos brought on by human-induced global warming, because we, and the rest of life, are all in it together.
We are focused on battery technology development as our top priority, because it makes progress on all other fronts possible. We also have advanced solar, wind and wheel motor technologies ‘waiting in the wings’.

Our Battery Goals

1.     Provide enough incredibly powerful, reliable and safe batteries to deliver electricity from renewable sources of energy whenever it is needed, and to stabilize grids at every scale.
2.    Provide abundant range and power in a very small battery, at a truly affordable price. At the very least, make it possible for a full battery electric vehicle to have a lower purchase price than the same (or equivalent) vehicle with an internal combustion engine. [‘Vehicle’ includes moving passengers or freight, by land, sea or air.] Meet NASA's 700 Watt-hours per kilogram capacity target for safe full battery electric commercial passenger aircraft by the end of 2019.
3.    Grow fast enough to enable renewable energy systems and battery electric vehicles to grow fast enough, to end use of fossil fuels within 15 years.​

Our Team

William Todorof
Chairman & CTO

Thin film solar photovoltaic, ceramic semiconductor pioneer William Todorof provides out-of-the-box discovery processes, unique experience at the intersection of invention, physics, ceramics and energy, and deep commitment to global energy sustainability – and to the possible. Over 25 years of research, modeling and design, and 5 years of physical development involving over 6,000 hand-built cathodes and 3,000 anodes, have brought him to the verge of a revolution in battery physics and performance.
