New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

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

Green Car Congress

A battery, based on electrodes made of sodium and nickel chloride and using thea new type of metal mesh membrane, could be used for grid-scale installations to make intermittent power sources such as wind and solar capable of delivering reliable baseload electricity. The work was supported by the French oil company Total S.A.

Electric Scooter vs Petrol Scooter : Huge benefits for India

Plug In India

You can use solar energy to power your EV now and go zero emissions. A petrol scooter has no option to be powered by solar energy. When you start an electric scooter, you can listen to the wind and birds! Petrol or crude oil is imported from outside India. The answer is NO - not on the same scale as oil.

MIT and Moscow State collaborating on advanced batteries, metal-air batteries and reversible fuel/electrolysis cells

Green Car Congress

Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge. Because solar and wind energy are intermittent, producing energy only when the sun shines or the wind blows, a method to capture and store energy for later use is needed.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The particles can compose up to 80 percent of the liquid’s weight while leaving it no more viscous than motor oil. At the depot, the spent fuel could be recharged with electricity from any source—solar, wind, hydroelectric, nuclear, or fossil fuels. The recharging could also be done at a service station or in the EV itself.

Promising EV Trends to Lookout For in 2023

Get Electric Vehicle

The batteries that use sodium instead of the pricey and rare lithium are the ones that are the closest to being on the market. The charge point operator (CPO) can store grid energy when it is affordable or locally produced solar energy and utilise it as backup power for rapid DC charging or during peak hours when electricity is costly.
