The paper reports a metal - free
flow battery that relies on the electrochemistry of naturally abundant, inexpensive, small
organic (carbon - based) molecules called quinones, which are
similar to molecules that store energy in plants and animals.
These sweeping wet - into - wet passes are
similar to the way Gerhard Richter drags paint with large acrylic squeegees, but the
flowing lines left by Lawlor's wide brushes are more human and
organic than Richter's geologic scrapings.
