Liquid air: A cool option for energy storage?

Envirotec Magazine

Liquid Air Energy Storage (LAES) uses electricity to cool air until it liquefies, so it can be stored until an opportune moment arrives when it can be brought back to a gaseous state and used for power generation. Katie Smith of law firm Reddie & Grose LLP examines where the approach fits into the energy storage landscape.

Ensuring safe and reliable lithium-ion battery performance

Also, poor thermal management reduces the electronic components’ efficiency because excessive heat increases electrical resistance and lowers the power and energy of the EV. These are applied in between heat source (battery) and heat sink (cooling plate/ribbon). Higher energy density requires powerful high-voltage batteries.

QuantumScape introduces a new cell format for solid-state EV batteries

Charged

The cell face and flexible packaging material are pushed out when each layer’s cell charges and anodes are plated with pure lithium metal. The FlexFrame design transfers heat from cell layers to the outer frame, which can be cooled from the back or sides. Fully charged cells have a face that’s nearly flush with the frame.

There’s gold (and lithium and cobalt) in all those EV battery packs

The Verge: Energy

Supply and demand There’s recently been some churn in the media about cooling demand for electric cars, but a quick look at the numbers shows demand is strong. Well, not literal gold, at least not much, but there is plenty of lithium, cobalt, and other materials that are good for batteries but hard to find in the earth.
