Synthesis of a polymeric 2,5-di-t-butyl-1,4-dialkoxybenzene and its evaluation as a novel cathode material

▶ Redox shuttles are frequently used for overcharge protection of Li-ion batteries. ▶ A polymeric analogue of the redox shuttle 2,5-di-t-butyl-1,4-dimethoxybenzene has been prepared. ▶ The novel polymeric analogue of the redox shuttle is a promising prototype of a new class of organic cathode materials for Li-ion batteries.
