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) Nature Energy 1, Article number: 16111 doi: 10.1038/nenergy.2016.111.

Voltage surge and transient suppression in EV chargers

Charged EVs

Clamping and crowbarring are related means of shunting transient/surge energy—which essentially means converting it to heat. This article originally appeared in Issue 66: October-December 2023 – Subscribe now. There are three main ways to deal with transients/surges: blocking, clamping and “crowbarring.”

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

Green Car Congress

The inert nanoshell facing the electrolyte is covered with the SEI but does not change volume, while the active yolk expands/shrinks in the internal cavity without SEI. They converted the alumina layer to titania (TiO 2 ), a better conductor of electrons and lithium ions when it is very thin. Earlier post.).

Customers could convert U.S. dollars into amazons—and, at least for the time being, they could convert them back, on demand, at a 1:1 exchange rate, perhaps for a small fee. The amazons could be converted frictionlessly into dollars. This would be an advantage for international consumers who wanted to avoid exchange-rate risk.
