PowerNaP Energy develops sodium‑ion batteries that replace lithium with abundant sodium and phosphorus, using a conductive phosphorus‑engineered anode to boost energy density toward lithium‑ion parity. This chemistry leverages sodium’s 1,000‑fold greater abundance and phosphorus’s high charge capacity to lower material costs and improve supply‑chain resilience. The resulting batteries target electric‑vehicle makers, residential storage providers, and other high‑volume battery integrators seeking affordable, high‑performance energy storage.

Problem
Current lithium‑ion batteries rely on scarce and costly lithium resources, leading to supply chain vulnerabilities and high material costs for large‑scale energy storage and electric vehicles.
Solution
PowerNaP Energy develops sodium‑ion battery technology that replaces lithium with abundant sodium and phosphorus. By engineering a conductive phosphorus‑based anode, the company significantly increases the energy density of sodium‑ion cells, aiming to match lithium performance while reducing material costs. The approach leverages sodium’s natural abundance—approximately 1,000 times more plentiful than lithium—and phosphorus’s ability to store up to eight times more charge than conventional hard‑carbon anodes. This enables cheaper, scalable battery solutions for electric vehicles, home energy storage, and other mobility applications.
Target Audience
Primary customers are manufacturers of electric vehicles, residential energy storage systems, and other high‑volume battery integrators seeking lower‑cost, high‑performance sodium‑ion solutions.
