At Tesla’s gig plant in Nevada, cells could be rolled out of partially recycled batteries by the end of the year.
An electric car powered by a clean and sustainable energy source is a eutrophication in Norway, so the carbon footprint of an electric vehicle is much lower than that of an internal combustion engine companion throughout its life cycle, transforming energy in liquid fuel into motion with low efficiency and high emissions. But the soul of electric cars, the large battery pack alone, accumulates considerable emissions, starting with the mining of lithium, and the extraction, processing, and cellularization of other raw materials also leaves a sizeable footprint. There are then ethical issues with the low cobalt use of NMC and MCA sites due to the significant role of Africa and child labor in mining, and the safety of today’s high-energy lithium-ion sites is partly guaranteed by this element. And as the share of electric cars in the vehicle market grows, so much extraction is needed from all components.

The LFP and many solid-state battery batteries already save cobalt, and Tesla plans to do the same for higher-energy-density cells. Similarly, there are steps to make lithium and nickel more environmentally friendly, but recycling can be the biggest way to curb emissions. In addition to recovering quantitative raw materials (lithium, cobalt, copper, aluminum, nickel, manganese, iron, graphite), a bunch of precious and rare earths can also be obtained from used cells, and analysts say it will be drastically by the middle of the decade. to move the EV sector cell hunger extraction and production capacity, and immediately stall the momentum of electric cars.

Co-founder and former chief technology officer of Tesla, J. B. Straubel that’s why he quit Elon Musk company and founded in Nevada Redwood Subjectst. Many companies extract raw materials from the battery and clean it up enough to make it safe cells, but it is just as expensive in small quantities as it is to build a hypercar by hand. Straubel’s goal is therefore high-capacity, mass and automated recycling, which could really boost when thousands of used EV battery packs and batteries captured for local energy storage run into thousands.

Redwood is already offering tons of recycled raw materials ready for battery production, and Panasonic has announced that it will purchase its copper plates from Tesla’s Nevada Giga plant to produce cells from partially recycled sources by the end of the year. Copper foil is required for anode fabrication, and Gigafactory in Nevada produces most of the 2170 format cells in Model 3 and Y.
By the end of 2022, @PanasonicNA will include Redwood’s copper foil, produced from recycled materials, back into new battery production at the Gigafactory. This will be the first time batteries will be recycled, remanufactured and returned to the same factory in a closed loop. https://t.co/w60pbK3ZJm— Redwood Materials (@RedwoodMat) January 4, 2022
Panasonic is still in the process of developing some sort of goliath batteries in the 4680 format, and the low price of the battery pack will be a key issue for the upcoming $ 25,000 Tesla model. This is partly due to faster and more space-saving cell production and structural integration, and partly due to cheaper raw materials obtained from recycled sources. Although the recent agreement has so far been signed between Panasonic and Redwood Materials, Tesla, which is itself engaged in (limited) recycling, may be interested in Straubel as a supplier.

Redwood promises 95% recovery of lithium, nickel, cobalt and copper from EV, mobile phones and all other cells, and will engage in cathode production in addition to recycling, supplying one million electric cars a year by 2025 and five million by 2030. . The ultimate goal is to keep the raw materials already extracted (at the cost of some loss) in the cell production-use-recycling cycle, thus reducing more harmful extraction. Straubel is also partnered by Ford and several smaller and larger players, so Redwood could have a continuous, high-volume battery source within a few years to drastically reduce its prices in parallel with the capacity increase, and ultimately the carbon footprint of cells and thus electric cars.
