MIT researchers develop optimized sulfidation separation process for rare earth and other key metals

Green Car Congress

New processing methods developed by MIT researchers could help ease looming shortages of the essential metals that power everything from phones to automotive batteries by making it easier to separate these rare metals from mining ores and recycled materials.

MIT, Brookhaven team develops simple method for stabilizing interfaces in solid-state lithium-ion batteries

Green Car Congress

Now, a team of researchers at MIT and Brookhaven National Laboratory has developed a way of achieving results that equal or surpass the durability of the coated surfaces, but with no need for any coatings. The findings are reported in an open-access paper in the journal Advanced Energy Materials.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% This would be many, many times more feasible than what has been proposed for all-electric aircraft. increase in block fuel burn.

MIT team develops data-driven safety envelope for lithium-ion batteries for EVs

Green Car Congress

Researchers at MIT, with a colleague from Tsinghua University, have developed a safety envelope for Li-ion batteries in electric vehicles by using a high accuracy finite element model of a pouch cell to produce more than 2,500 simulations and subsequently analyzing the data with Machine Learning (ML) algorithms. —Li et al.

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. We think that the way to enable the use of electricity in these vehicles is with a plug-in hybrid.

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. Geologic pumped hydroelectric storage works by pumping water to a reservoir behind a dam when electricity demand is low. Earlier post.).

MIT, Stanford and Toyota Research Institute use AI to predict accurately the useful life of batteries

Green Car Congress

Scientists at the Massachusetts Institute of Technology (MIT), Stanford University and the Toyota Research Institute (TRI) have discovered that combining comprehensive experimental data and artificial intelligence provide the key for accurately predicting the useful life of lithium-ion batteries before their capacities started to wane.
