A Nile red dye cathode with an asymmetric redox unit for lithium organic batteries†
Abstract
A Nile red (NR) dye cathode with an asymmetric redox structure of para CN and CO bonds was developed for use in an efficient lithium organic battery with a good capacity of 125 mA h g−1 and two visible discharge/charge voltage plateaus (≈2.0 V and ≈1.7 V). The NR cathode demonstrated the advantages of employing cost-effective dyes to achieve multigradient voltage platform regulation.
