Biography

Cy Fujimoto is a Principle Member of the Technical Staff in the Nanoscale Sciences Department at Sandia National Laboratories. Cy’s work focuses on developing membrane separators for electrochemical applications. In the Office of Electricity’s program, he is developing membranes for several flow battery chemistries and partners with various national labs and industrial collaborators. This work has led to several patents and recently several of these patents were licensed by a US materials company.
