Prieto Battery
www.prietobattery.com ↗Develops sodium-ion batteries built for fast charging (under 10 minutes), a wide operating range (-70°F to 200°F), and no thermal runaway, using an electroplating-based process designed to scale through contract manufacturing; targets defense and national security, data centers, and critical infrastructure like hospitals and utilities
The Current Angle
Founded 2009, one of the longer-running Colorado battery companies; holds 28 patents; backed in part by Stanley Black & Decker. Spent most of its history on 3D lithium-ion architecture before pivoting to sodium-ion aimed at defense and data centers, and began federal lobbying in 2025 to pursue government funding. Now sits alongside Peak Energy and Mana Battery in an unusually deep Colorado sodium-ion cluster
