![]() He declined to say how big a stake he owns in the private firm. ![]() Redwood could eventually go public, but there’s no plan to do so currently, said Straubel. Electric vehicle battery-recycling technology and infrastructure has advanced rapidly in the last decade, with new businesses emerging to help avoid a future where end-of-life EV batteries. Right now, Co can make up to 20 of the weight of the cathode in lithium ion EV batteries. The company has since raised more than $1 billion from investors including Ford, Fidelity, Bill Gates’ Breakthrough Energy Ventures and Amazon’s Climate Pledge Fund and generates an undisclosed amount of revenue from sales of recycled commodity metals. EV batteries can have up to 20 kg of Co in each 100 kilowatt-hour (kWh) pack. He left Tesla in July 2019 to focus on battery recycling at Redwood. Straubel, who worked to create Tesla’s first battery packs and motors as its CTO, oversaw the development of the EV company’s Gigafactory in Sparks, Nevada, the largest U.S. It is producing high-capacity Ni-rich cathode materials and low-expansion anode materials for EV batteries, and has a set of technologies such as NCM, NCMA and NCA cathode, silicon anode and materials for solid-state battery. Now its focus is to expand that business and use those recycled materials to make new battery components, as well as purchasing some minerals from metals suppliers. POSCO Future M is a global advanced materials company dedicated to battery for future mobility. The estimated total capacity is 26.136 Ah, while total energy is estimated at 96-99 Wh (assuming at 3.7-3.8 V). When Redwood came out of stealth, its initial focus was on collecting massive amounts of used batteries and electronics to extract and reuse lithium, cobalt, nickel and other high-value metals. Teslas 4680-type battery cell weight was 355 g. ![]() Battery metals and minerals recovered by Redwood Materials’ recycling operation.
