MIT study finds lithium sulfide solid electrolyte more brittle than ideal for batteries

Green Car Congress

Researchers at MIT have probed the mechanical properties of Li2 S –P 2 S 5 —thought to be a promising amorphous lithium-ion-conducting solid electrolyte—to determine its mechanical performance when incorporated into batteries. Crystalline and amorphous sulfide electrolytes (e.g., in the case of silicon anodes). Resources.

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

Densities for steel springs and Li-ion batteries provide a comparison. Nanotube springs might thus find applications in extreme conditions, such as for devices to be used in an oil borehole subjected to high temperature and pressure, or on space vehicles where temperature can fluctuate between extreme heat and extreme cold.

CMU/MIT study finds large-scale battery manufacturing will do little to reduce unit costs past a 200-300 MWh annual production level

Green Car Congress

A new techno-economic analysis by researchers at Carnegie Mellon University (CMU) and MIT has found that economies of scale for manufacturing current Li-ion batteries for light-duty EV applications (in this case, prismatic pouch NMC333-G batteries and packs) are reached quickly at around 200-300 MWh annual production.
