A team from metals research institute SWERIM in Sweden has reported on a smelting reduction process to recover cobalt, nickel, manganese and lithium simultaneously from spent Li-ion batteries. A paper on their work was published in the Journal of Power Sources. Results from the laboratory-scale smelting reduction (carried out at 1,550°C in an Ar atmosphere… Read more »

New analytical model from Rice University helps fine-tune battery performance
Rice University engineers have devised a simpler and more efficient way to predict battery performance, which they claim is 100,000 times faster than current modeling techniques. The analytical model developed by materials scientist Ming Tang and graduate student Fan Wang of Rice University’s Brown School of Engineering doesn’t require complex numerical simulation to guide the… Read more »
The monster that wouldn’t die—varied reactions to GM’s electric Hummer unveil
EV fans tend to be divided into two groups: Greenies and Car Guys, and reaction to GM’s upcoming Hummer EV has, unsurprisingly, been divided along those lines. Hummer good Most of the media is ecstatic over the new machine. Many are praising its “bad-ass” looks (GM says it wanted to make it look “less military”… Read more »
Li-Cycle to build battery recycling hub in upstate New York
Battery recycling specialist Li-Cycle will invest over $175 million dollars in a lithium-ion battery recycling “Hub” at Eastman Business Park in upstate New York. The new facility will work in conjunction with Li-Cycle’s “Spoke” facility, which is already located at the Rochester site. Li-Cycle plans to begin construction on the Hub facility in 2021. Li-Cycle’s… Read more »
Li-Cycle recovers usable battery-grade materials from shredded Li-ion batteries
Q&A with CEO Ajay Kochhar It’s usually one of the first objections cited by EV naysayers: batteries can’t or won’t be recycled, and they contain hazardous materials that will end up in landfills. In fact, no such sinister scenario is likely—most of the components of Li-ion batteries are valuable, and it’s quite feasible, technically and economically,… Read more »
UN highlights social and environmental impacts of surging demand for battery raw materials
Demand for raw materials used in the production of EV batteries is expected to soar, and the UN trade body, UNCTAD, says the industry urgently needs to address the social and environmental impacts of the extraction of raw materials. UNCTAD predicts that the market for EV batteries will grow from an estimated $7 billion to… Read more »
Northvolt to supply €2 billion worth of green battery cells to BMW
The BMW Group has signed a long-term battery cell supply contract worth 2 billion euros with Swedish supplier Northvolt. The cells will be produced beginning in 2024 at the Northvolt Ett gigafactory, which is currently under construction in Skellefteå in northern Sweden. Northvolt Ett in Sweden is to go on line in 2021 with an… Read more »
Specialized motor materials and constructions (Part 2)
The previous article in this two-part series looked at specialized materials that are (or will be) used in motors; the focus this time will be on the innovative methods of construction that make motors more suitable for EV traction applications. Separating the wheat from the chaff is especially important here, because hyperbole (and outright fantasy)… Read more »
China sales and impending Semi production send Tesla shares into the stratosphere
Tesla’s stock briefly cracked the thousand-dollar mark, setting a new all-time high and raising the company’s market valuation to over $180 billion, making it the world’s most valuable automaker, after Toyota. The main impetus for the stock surge seems to have been a stellar sales report from China. Tesla sold 11,095 Shanghai-made Model 3s in… Read more »
Report: EVs will drive demand for nickel sulfate over the next decade
In a newly-released report on the nickel sulfate industry, Roskill forecasts that the expanding EV industry will become the key driver of growth in nickel demand. In the past, the market for nickel sulfate was largely driven by the plating industry and non-Li-ion battery applications, such as NiMH and NiCd batteries, but year-over-year growth in… Read more »
