Our take
Redwood Materials, the brainchild of former Tesla co-founder and CTO JB Straubel, is making waves in the sustainable energy sector with its strategic approach to battery recycling and domestic supply chains for lithium-ion batteries.
The company is dedicated to creating a fully closed-loop supply chain by manufacturing critical battery components using as many recycled batteries as possible, effectively localising a 50,000-mile global battery supply chain on a single site. This strategy aims to address the critical issue of material sourcing, particularly the reliance on China for battery materials.
Redwood Materials closed a Series E funding round in 2025 at a post-money valuation exceeding $6B. This financial backing positions the company to continue expanding its capacity, further strengthening the US's domestic battery supply chain. Its ambitious goal of enabling customers to purchase battery materials made in the US is aligned directly with the broader political objective of onshoring critical industries, as emphasised in the USA's 2022 Inflation Reduction Act.
