UK Researchers Developing Rechargeable Lithium-Air Battery; Up to 10X the Capacity of Current Li-ion Cells

Green Car Congress

Oxygen drawn from the air reacts within the porous carbon to release the electrical charge in this lithium-air battery. Researchers in the UK are developing a rechargeable lithium-air battery that could deliver a ten-fold increase in energy capacity compared to that of currently available lithium-ion cells.

2023’s Top Stories About Energy

Cars That Think

Energy storage and nuclear fusion—two reliable crowd pleasers when the crowd you’re talking about is readers of IEEE Spectrum —are well represented among our most widely read energy stories of 2023. meters long, weigh 62 kilograms, and store 3 kilowatt-hours. But atop the list are a couple of surprises. Number one?

Paul Scherrer Institute and Toyota RD team finds tiny memory effect in Li-ion batteries; implications for vehicle battery management systems

Green Car Congress

The memory effect of the battery is written in a cycle with partial charging (here, 50% of the battery’s storage capacity) followed by complete discharge. In the subsequent cycle, the memory effect is evident through an overvoltage (small “bump”) at precisely the same point at which the partial charging cycle terminates.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Electricity is a commodity that is bought and sold, and yet unlike most other commodities, it cannot easily be stored. The need for large-scale electrochemical energy storage as a grid-stabilizing source of demand disappeared. In such an emergency, a bidirectional EV with charge to spare could come to the rescue.

KIT/IIT team demonstrates suitability of high-entropy oxides (HEO) as conversion materials for reversible energy storage

Green Car Congress

Novel materials can considerably improve storage capacity and cycling stability of rechargeable batteries. Among the most important properties of batteries are their storage capacity and their cycling stability, i.e. the number of possible charging and discharging processes without any loss of capacity.
