Tiivistelmä
The performance of the negatively charged aspartic acid-functionalized naphthalene diimide (ASP-NDI) in a flow battery is investigated in this article. The high concentration ASP-NDI/ferrocyanide flow battery presented cycled for 79.8 days with an average coulombic efficiency of 99.9% and an energy efficiency of 87.5% at 20 mA cm−2 while accessing an over 90% of the theoretical capacity of ASP-NDI with a capacity fade rate of 0.0275% per day that is the lowest reported for the NDI-based flow batteries to date.
