GM and LG Chem’s Ultium Cells partners with Li-Cycle to process manufacturing waste
Li-Cycle’s approach is various from more traditional recycling processes, co-founder Ajay Kochhar informed TechCrunch. Traditional recycling usage a pyrometallurgical, or heat, process. With this process, batteries go into a heating system and excess product, like plastics and the electrolyte, are burned off, leaving around a 50% healing rate for the important raw materials.
Ultium Cells LLC, a joint venture in between General Motors and LG Chem, has actually been progressively constructing up its battery cell production capability in the U.S. because the endeavor was first announced in December 2019. But with each battery cell they produce, they’ll also produce waste– tricky-to-handle waste that likewise has too much intrinsic valuable to toss into a garbage dump.
Li-Cycle likewise differs from competitors like Redwood Materials, which also utilize high-temperature, Kochhar discussed. Redwood processes things like consumer electronic devices, which requires various approaches. Li-cycle uses a hydrometallurgical procedure that shreds– in fact shreds, like a paper shredder– the battery products in an immersed, exclusive solution. Doing it this method reduces the thermal danger of a fire and recovers approximately 95% of the battery materials (Redwood likewise declares a recovery rate of 95-98%). By not burning anything off, the business also prevents producing potentially harmful emissions, Kochhar said.
The business has 2 recycling “spokes,” where shredding and mechanical separation takes place, in Rochester and Ontario, Canada, with a third commercial facility being built in Arizona. As soon as the Arizona facility becomes functional, Li-Cycle will be able to process around 20,000 metric loads, or 4 gigawatt-hours, of lithium-ion batteries each year. It’s likewise building what it calls a “center” to make the battery chemicals in Rochester, which will have an annual capability to process around 60,000 metric tons of battery scrap and “black mass” (a mix of cathode and anode product, and among the outputs from the business’s “spokes”).
Instead of tossing it away, Ultium is sending it to a recycler. The endeavor has executed a contract with Canadian company Li-Cycle to recycle important materials from the scrap produced from Ultium’s manufacturing processes from its Lordstown plant, starting later on in 2020. The materials from the Lordstown location will be sent out to Li-Cycle’s recycling area in Rochester, New York, to be processed and returned to the battery supply chain.
(opens in a brand-new window)The cathode and anode product is transformed into battery-grade chemicals, like lithium carbonate, nickel sulfate and cobalt sulfate. Li-Cycle deal with a business Traxys, which buys the chemical product.
Li-cycle uses a hydrometallurgical process that shreds– really shreds, like a paper shredder– the battery materials in an immersed, exclusive option. Doing it this method reduces the thermal threat of a fire and recuperates up to 95% of the battery materials (Redwood also claims a healing rate of 95-98%). Once the Arizona facility ends up being functional, Li-Cycle will be able to process around 20,000 metric heaps, or 4 gigawatt-hours, of lithium-ion batteries every year. Significantly, the business also recycles R&D scrap from different car manufacturers, providing Li-Cycle “a kind of first appearance at what’s coming down the pipe” in terms of battery technology, Kochhar stated. That helps the company stay on top of the newest battery chemistries and innovations, like solid-state or lithium iron phosphate (LFP), and establish recycling procedures appropriately.
Ultium in April announced a 2nd $2.3 billion U.S.-based battery factory in Spring Hill, Tennessee that is because of open in 2023. Both factories will supply the automaker with the cells required for the 30 electric automobile designs it prepares to release by mid decade. However, it is not known if Li-Cycle will process waste from this plant, too.
“This need to be one commercial example […] that EV batteries will not enter into a garbage dump,” he said. “They’re very valuable. The innovation’s here to handle that in an economically and ecologically friendly fashion.”
General Motors and LG Chem are plainly identified to scale their battery cell manufacturing. Around 5-10% of the output of a cell manufacturer is this excess scrap. Thinking about that the Lordstown center will be capable of producing 30 gigawatt hours of capability each year, it’s sure to produce a large quantity of waste material. (For viewpoint, Tesla’s factory in Nevada has a 35 GW-hour capability.)
Especially, the company likewise recycles R&D scrap from various automakers, giving Li-Cycle “a kind of very first take a look at what’s coming down the pipe” in terms of battery innovation, Kochhar stated. That helps the company remain on top of the latest battery chemistries and technologies, like solid-state or lithium iron phosphate (LFP), and establish recycling processes appropriately. Li-Cycle already processes some LFP batteries; in those instances it remakes the phosphate back into a fertilizer additive.
“And where it goes from there is back into cathode making and back into the broader economy and battery supply chain,” Kochhar said. The next step would be a “real circular economy closed loop” where the same product used by a maker is returned back to it.

In this case, Kochhar said he hopes individuals see this collaboration as a proof point for the financial and environmental case for electrical automobiles.
It deals with 14 various automotive and battery manufacturers (though not all of those offers are public), along with automobile dealers and auto recyclers to accept and process invested lithium-ion batteries.
