Reply to comment by DixenSyder in Scientists lower price of lithium's best competition - flow batteries - by 20%. Makes the battery effectively equal to or cheaper than lithium ion when spread over 30 years (flow battery lifetimes are effectively infinite with light repowering efforts). by PorkyPigDid911

You really think it will be costlier to extract those metals from the used batteries than from Earth? Lithium, for example, is 7% of battery's weight. Guess the Lithium concentration in the brine they extract it from? They are lucky to get 1%.
