Redwood has closed a $350 million Series E funding round, led by Eclipse with participation from NVentures, NVIDIA’s venture arm, underscoring strong investor confidence in the company’s rapid growth across its two integrated business lines: critical materials-including cobalt, nickel, copper, lithium, and cathode active material-and grid energy storage, focused on very large-scale, low-cost solutions with optimal integration.The funding arrives at a crucial moment. Domestic demand for key materials and energy storage is growing. This is happening because of global supply issues. Redwood plans to meet energy needs for AI infrastructure and industrial electrification. They will provide U.S.-made, scalable battery energy storage systems.

These systems improve stranded grid capacity. They improve the efficiency of baseload assets. They also lower the unpredictability of renewable sources. “By combining deep materials and manufacturing expertise with advanced power electronics and software, Redwood is creating a new generation of U.S.-made energy storage systems-scalable, low-cost, and designed to power data centers, industry, and the grid-reducing reliance on imported LFP batteries,” the company stated. The new capital will accelerate energy storage deployment, expand refining and materials production capacity, and grow engineering and operations teams, positioning Redwood to lead American energy innovation and critical-minerals independence.
