Overview

Redwood Materials is a privately held battery-recycling, critical-materials, battery-component, and energy-storage company founded by former Tesla CTO JB Straubel. It is building a circular U.S. battery supply chain by recovering minerals from battery scrap and end-of-life batteries, refining them, manufacturing cathode active material and other battery components, and repurposing EV batteries for grid and data-center storage.

Primary product

Integrated battery circularity platform: lithium-ion battery recycling and refining, battery-grade critical materials/cathode active material, and Redwood Energy repurposed-battery energy-storage systems.

2017

Headquarters

Carson City / Northern Nevada, Nevada, United States

Team size

Approximately 1,100–1,200 employees reported in 2025–2026; other commercial databases report approximately 560–600, so public estimates are inconsistent.

Work & culture

Company materials describe a mission-driven, inclusive, collaborative and action-oriented culture focused on accelerating the energy transition. Employees emphasize chemistry, materials science, automation, advanced equipment design, hard technical problems and rapid execution. Independent employee-generated benefit/culture signals are mixed and should not be treated as company-approved.

Visa sponsorship

Yes

Compensation

Public job postings provide role- and location-specific ranges; one California DevOps posting listed $168,500–$276,000. H-1B/LCA data indicates sponsorship activity and a reported median offered salary around $130,000, with filings ranging roughly from $90,000 to $350,000. Equity is reported for many roles; benefits and retirement support are described as average or mixed by third-party sources.

Benefits

Medical, dental and vision insurance

Flexible or unlimited PTO for salaried employees (employee-reported)

Stock options/equity reported in job and employee sources

Parental/family leave

Product & market

Pricing

Not publicly listed; appears to be negotiated B2B pricing for recycled materials, battery components and storage deployments, potentially via supply/offtake and project contracts.

Differentiators

—Vertically integrated recovery, refining and materials manufacturing rather than recycling alone
—Closed-loop domestic supply-chain strategy for U.S. batteries
—Ability to recover materials from both manufacturing scrap and end-of-life packs
—Reported recovery rate above 95% for lithium, nickel, cobalt and copper
—Combination of recycling/materials production with second-life battery energy storage
—Large U.S. campus footprint and planned Carolina expansion
—Relationships spanning automakers, cell manufacturers, recyclers and energy/data-center customers
