However, ways production n...

Flow batteries are prospective devices for cheap, grid-scale storage of electricity generated from renewable power. Writing in Science, Feng et al. demonstrate how functionalization can activate the organic molecule fluorenone as a promising charge-storing reactant aqueous redox-flow batteries. One most important goals fight against climate change is to meet our energy needs by harnessing power...
