Air-stable lithiated cathode material based on 1,4-benzenedisulfonate backbone for organic Li-ion batteries

Abstract

To meet the current market demands as well as the emerging environmental concerns there is a need to develop low polluting battery technologies. Organic electrode materials could offer the possibility of preparing electrode materials from naturally more abundant elements and eco-friendly processes coupled with a simplified recycling management. However, the potential use of organic electrode materials for energy storage is still challenging and a lot of developments remain to be achieved. For instance, promoting high-energy Li-ion organic batteries inevitably require the development of lithiated organic electrode materials able to be charged (delithiated) at high enough potential (> 3 V vs. Li+/Li0); a challenging point rarely discussed in the literature. Here, we evaluate tetralithium 2,5-dihydroxy-1,4-benzenedisulfonate as air-stable lithiated cathode material for the first time and the reversible Li electrochemical extraction. Quite interestingly, in comparison with the dicarboxylate counterpart, it was observed that the theoretical two-electron reaction is readily reached with this organic structure and at an overage operation potential of 300 mV higher.
