Designing Robust Redox Shuttles for Overcharge Protection in Lithium-Ion Batteries

摘要

(1) In addition to radical cation stability, redox shuttle performance is related to stability of the neutral compound to the battery electrolyte and its resistance to reduction at the anode (2) Small changes in substituent identity and placement can result in dramatic changes in performance and must be carefully considered (3) Current Work: analysis of stability & reactivity of dimethoxybenzene derivatives (4) Related work: evaluation of phenothiazines as catholytes in organic redox flow batteries (A.
