Panasonic battery cells made on the Gigafactory it operates with Tesla will use extra recycled supplies by the top of 2022 as a part of an expanded partnership with startup Redwood Supplies.
Panasonic mentioned Tuesday on the 2022 CES tech commerce present that Redwood Supplies will begin supplying it with copper foil produced from recycled supplies, a essential element of the anode aspect of a battery cell. Redwood will start producing the copper foil within the first half of the 12 months; the copper foil will then head to Panasonic the place it is going to be utilized in cell manufacturing by the top of the 12 months.
The announcement marks Panasonic’s push to make use of extra recycled supplies, which in flip helps it cut back the quantity of newly mined uncooked supplies it should depend on; it additionally exhibits how Redwood continues to develop its enterprise.
Electrical autos on the street in the present day are geared up with lithium-ion batteries. A battery incorporates two electrodes. There’s an anode (unfavorable) on one aspect and a cathode (optimistic) on the opposite. An electrolyte sits within the center and acts because the courier that strikes ions between the electrodes when charging and discharging. The anode is usually manufactured from copper foil coated with graphite.
As automakers ramp up the manufacturing of electrical autos — and finally exchange these with vehicles and vehicles geared up with inside combustion engines — demand for batteries and the supplies inside them is anticipated to skyrocket. Almost each main automaker that dedicated to electrifying their automobile portfolio have additionally locked in partnerships with battery cell producers and different suppliers in an effort to shore up its provide chain.
Redwood Supplies, which was based by former Tesla CTO JB Straubel in 2017, is aiming to create a round provide chain. The corporate recycles scrap from battery cell manufacturing in addition to shopper electronics like cellular phone batteries, laptop computer computer systems, energy instruments, energy banks, scooters and electrical bicycles. It then processes these discarded items, extracting supplies like cobalt, nickel and lithium which are sometimes mined, after which provides these again to Panasonic and different prospects (It has additionally publicly disclosed that it’s working with Amazon and AESC Envision in Tennessee).
The intention is to create a closed loop system that can finally assist cut back the price of batteries and offset the necessity for mining.
Redwood’s announcement earlier this 12 months that it had bought 100 acres of land close to Gigafactory was a touch at this expanded partnership with Panasonic.
“Our work collectively to determine a home round provide chain for batteries is a vital step in realizing the complete alternative that EVs must form a way more sustainable world,” Panasonic Power of North America President Allan Swan mentioned throughout the presentation.
Redwood introduced in September plans to supply essential battery supplies proper in the USA. The corporate plans to construct a $2 billion manufacturing facility that can produce cathodes and anode foils as much as a projected quantity of 100 gigawatt-hour per 12 months’s price of supplies; that’s sufficient for a million electrical autos, by 2025.
