Stealth Mode

Helios led the Series B in 2017 when the company was focused on the commercialization of a novel cathode material. [Stealth Mode Company] successfully built manufacturing capacity in China and became the sole independent supplier of high end cathode there. The company has since split into two entities: the China cathode business which is attracting acquisition interest from major industrials and [Stealth Mode Company] SE which is focused on a novel solid state lithium ion battery technology. Helios has a Board Observer Seat.
