Flow batteries have been around for a while. First I've heard of trying it with Lithium chemistry.

Interesting... Wish they'd give more details.

Prof at MIT, been thinking about the problem for 10 years...sounds good, that's the kind of prepared mind, focus, and persistence required to solve a difficult problem.

As with fuel cells, the new battery can store large amounts of energy without also needing large amounts of supporting materials to extract it, Chiang says.

Last I checked fuel cells didn't store any energy.

cut cost 85% , 10,000 to 1,500 ? that would be too great ! thermal management would be easy . brings new meaning to top charge . the potential of much longer life , more active materials like sodium (2x better then lithium and dirt cheep) and silicon ( 400% silicon expansion problem , not a problem , 10x more effective then carbon ) . For off grid power , a small battery with large reagent tanks means cheaper multi megawatt storage , also transport of stored energy . And some one was saying batteries can't go much further .

the fuel tanks store the energy the fuel cells convert it . they do continue to carry a charge without fresh reactants like a capacitor .
