Weven Energy manufactures modular sodium‑ion battery systems for utility‑scale and commercial stationary storage. The packs use a proprietary cathode that provides higher thermal stability and longer cycle life than typical lithium‑iron‑phosphate cells, while eliminating rare‑earth materials and sourcing raw inputs within the EU to reduce cost and geopolitical risk. An integrated battery‑management system ensures real‑time monitoring and compliance with IEC 62619 and UL 2054 safety standards.

Problem
The energy storage market relies heavily on lithium‑ion batteries, which face supply chain bottlenecks, safety concerns, and environmental impacts due to the use of scarce and hazardous raw materials. These constraints increase costs and limit the scalability of renewable‑energy integration and stationary storage projects.
Solution
Weven Energy offers sodium‑ion battery systems that replace lithium with abundant sodium, eliminating the need for rare‑earth components. The technology incorporates a proprietary cathode formulation that delivers higher thermal stability and extended cycle life compared with conventional lithium‑iron‑phosphate packs. By sourcing raw materials within the European Union, the solution reduces geopolitical risk and lowers material costs. The batteries are designed for modular deployment in stationary applications, providing a safe, efficient, and sustainable alternative for large‑scale energy storage. An integrated battery‑management system monitors performance and ensures compliance with industry safety standards.
Target Audience
Primary customers are utility‑scale and commercial stationary storage providers, renewable‑energy developers, and industrial facilities seeking safe, cost‑effective battery solutions for grid balancing and backup power.
