New MIT metal-mesh membrane could solve longstanding problems with liquid metal displacement batteries; inexpensive grid power storage

Green Car Congress

A new metal mesh membrane developed by researchers at MIT could advance the use of the Na–NiCl 2 displacement battery, which has eluded widespread adoption owing to the fragility of the ?"-Al The results could make possible a whole family of inexpensive and durable materials practical for large-scale rechargeable batteries.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V versus Li/Li +. V in O x− (condensed phase) → O 2 (gas).

MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

A team of researchers at MIT and Tsinghua University has developed a high-rate, high-capacity and long-lived anode for Li-ion batteries comprising a yolk-shell nanocomposite of aluminum core (30 nm in diameter) and TiO 2 shell (~3 nm in thickness), with a tunable interspace (Al@TiO 2 , or ATO). Earlier post.).

Could Sucking Up the Seafloor Solve Battery Shortage?

Cars That Think

Reeling from a crushing shortage of semiconductor chips for vehicles, carmakers also face another looming crisis: producing enough batteries to drive the global pivot towards electric vehicles. Texas is top of The Metals Company's list for the processing plant given the state's ports and access to cheap renewables. "We

GM Shanghais the Volt

Plugs and Cars

The Technology Review published by MIT reports on the hydrogen fuel cell version of the Volt announced in Shanghai. If you're going to the trouble of building a plug-in and therefore have an electric drive train and a battery capable of storing a charge, then you could have a cheap gasoline engine along with you, or an expensive fuel cell."
