ACS Applied Energy Materials 2, no. 6: 4016-4021.2574-09622574-0962http://nrs.harvard.edu/urn-3:HUL.InstRepos:42482311Here we report a symmetric all-quinone aqueous battery based entirely on earth-abundant elements that uses a naturally occurring dye as the redox-active material in both positive and negative electrodes. We demonstrated a symmetric all-quinone cell with 1.04 V of open circuit voltage, 163 mAh/g of capacity, and 100 cycles at 10C with 100% of depth of discharge. The use of the same quinone in a symmetric setup expands the repertoire of inexpensive redox-active materials for aqueous rechargeable batteries, and the simple cell design will enable optimizations toward safe, cheap, light-weight, and flexible electronics in future.en-USJournal Article2020-02-1610.1021/acsaem.9b00691
