Redwood Materials reportedly cuts 5% of staff after $350M raise

By Eric November 29, 2025

In a significant advancement for sustainable technology, Redwood Materials, a battery recycling and cathode production company founded by former Tesla CTO JB Straubel, has begun utilizing recycled battery materials to manufacture energy storage solutions specifically designed for artificial intelligence (AI) data centers. This innovative approach not only addresses the growing demand for energy in AI applications but also promotes a circular economy by repurposing materials that would otherwise contribute to electronic waste. The company, which has been at the forefront of battery recycling, aims to reduce reliance on newly mined materials while simultaneously decreasing the carbon footprint associated with battery production.

Redwood Materials’ initiative comes at a critical time when AI-driven technologies are experiencing exponential growth, leading to increased energy consumption in data centers. By leveraging recycled materials, Redwood is creating high-performance battery systems that can efficiently store and deliver energy, thus supporting the intensive computational needs of AI applications. For instance, the company has developed advanced cathode materials from recycled lithium-ion batteries, which not only enhance energy density but also improve the overall sustainability of energy storage solutions. This innovative recycling process helps to minimize the environmental impact of battery production and aligns with global efforts to transition towards greener technologies.

The implications of Redwood’s efforts extend beyond just energy storage; they represent a broader shift in the tech industry towards sustainability and responsible resource management. As AI technologies continue to proliferate, the demand for efficient and eco-friendly energy sources will only increase. By integrating recycled materials into their products, Redwood Materials is setting a precedent for other companies in the tech sector to follow suit. This move not only showcases the potential of recycling in addressing the resource challenges posed by modern technology but also highlights the critical role that innovators like JB Straubel play in shaping a more sustainable future. As the industry continues to evolve, Redwood’s pioneering work could serve as a model for how to balance technological advancement with environmental stewardship.
