Brief Timeline

2024
Discovery Phase

PowerNaP studies phosphorus’s potential in solid state sodium batteries with support from Breakthrough Energy’s Explorers program. Halfway through the program, PowerNaP CTO and co-founder Benjamin Rupert tests our engineered phosphorus material with a liquid electrolyte and discovers: it works.

Optimization Phase

With continued support from Breakthrough Energy, PowerNaP is building out its lab in San Leandro, California. Here, we’ll continue to optimize our material and processes for performance and mass-manufacturability.
