PowerNaP Energy is a battery materials company.
We envision a world with battery storage in every home and an electric vehicle for every driver. To achieve this promise, we engineer advanced materials to increase the energy density of sodium-ion batteries, raising their performance to parity with lithium at a fraction of the cost.
We are a group of entrepreneurs, scientists, engineers, and industry veterans.

Brief Timeline
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.
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.
