摘要

In this article, tannic acid (TA), as an earth-abundant natural polymer, has been creatively proposed as a desirable organic anode material for lithium ion batteries (LIBs). Most importantly, it has been observed that the substitution of different concentrations of lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) for lithium hexafluorophosphate (LiPF_(6)) can significantly restrain the dissolution of TA. This fact implies that LiTFSI, especially at high concentrations, is beneficial to accelerate electrochemical kinetics, enlarge the specific capacity, improve the rate performance, and prolong the cycling life for organic LIBs.
