Fort Collins-based Prieto Battery expects to have a prototype of its lithium-ion battery ready to demonstrate by early January. Prieto Battery was the first startup launched in 2009 by Cenergy, the business arm of Colorado State University’s Clean Energy Supercluster. “It will be our first prototype, with lots of optimization still to do,” said Amy Prieto, a CSU chemistry professor and company founder. “But it will be the first time to demonstrate the architecture and that all of the elements make sense.”
