SeaLion Energy

The coating protects critical interfaces and preserves performance, and the company says it extends useful battery life up to tenfold without changing the underlying chemistry. SeaLion is also working on regenerating cells at end of life, and says the approach is compatible with solid-state cells.

SeaLion is a Carnegie Mellon University spinout based in Pittsburgh, Pennsylvania, led by founder and CEO Reeja Jayan. It is funded by ARPA-E, the US Department of Energy and CMU's Scott Institute for Energy Innovation. It targets robotics and autonomous systems, grid and commercial storage, defense platforms and electric vehicles.
