Liquid Metal Battery for grid storage/solar time-shift

Post by spinningmagnets » Jun 18 2018 6:26pm

Not useful for ebikes, E-moto or EV cars, but...for grid storage?...this is sounding like the future, by a large margin. There are now solar panels that emphasize electrical generation in the UV range, so they can harvest energy even on a cloudy day.

Unusually affordable, and incredibly long-lasting, made from abundant elements...

That is really awesome! I hope it becomes a reality.

But its not all roses !....

........EnerVault, which was developing what are known as flow batteries, put itself up for sale after failing to find additional investors in 2015. Later that year, liquid-metal battery startup Ambri laid off a quarter of its staff. Around that same time,.........

Most of the molten metal elecrode and/or molten salt electrolyte stuff works phenomenally well both on paper and in a small test cell.

Then in practice the God's of corrosion tend to frown on letting scaled versions survive for long.
Each carcinogen vapor exposure includes a dice roll for cancer.

Each mutagen vapor exposure includes a dice roll for reproductive genetic defects in your children.

Each engine start sprays them into a shared atmosphere which includes beings not offered an opportunity to consent accepting these cancer experiences and defective genetics life experiences.

Every post is a free gift to the collective of minds composing the living bleeding edge of LEV development on our spaceship.

The Redflow batteries in Australia look like they are working OK, with a few relatively minor teething problems.

Aren’t they flow batteries and not molten salt.

It seems Sadoway and MIT have not quite settled on exactly how to do this..
They are now experimenting with a metal mesh "membrane" between the molten layers..
http://news.mit.edu/2018/metal-mesh-mem ... nergy-0122
....But Sadoway and his team took a different approach, realizing that the functions of that membrane could instead be performed by a specially coated metal mesh, a much stronger and more flexible material that could stand up to the rigors of use in industrial-scale storage systems.
“I consider this a breakthrough,” Sadoway says, because for the first time in five decades, this type of battery — whose advantages include cheap, abundant raw materials, very safe operational characteristics, and an ability to go through many charge-discharge cycles without degradation — could finally become practical.
Note that final comment..."could finally become practical". ?
