The polyquinone nonylbenzo-hexaquinone (NBHQ), has been investigated as a cathode material for Li cells. At first its reduction gives rise to the formation of a radical-anion which forms a stable complex with Li+ . Successively, a direct two-electron reduction of same of the remaining quinone grups occurs. This second step is reverible and allows cells of the type Li/LiClO4 – PC,DMC/NBHQ,C to be cycled for more than 500 cycles between 3.5 and 2.0 V at the C/2 discharge rate (C is theoretical capacity of the catode)

Abstract
The polyquinone nonylbenzo-hexaquinone (NBHQ), has been investigated as a cathode material for Li cells. At first its reduction gives rise to the formation of a radical-anion which forms a stable complex with Li+ . Successively, a direct two-electron reduction of same of the remaining quinone grups occurs. This second step is reverible and allows cells of the type Li/LiClO4 – PC,DMC/NBHQ,C to be cycled for more than 500 cycles between 3.5 and 2.0 V at the C/2 discharge rate (C is theoretical capacity of the catode)I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
