Abstract

Graphical abstract: Highlights: A novel hypercrosslinked Poly-Pillar[5]quinone (Poly-P5Q) polymer has been prepared and applied as electrode material in Li-ion batteries. The novel synthetic route of Poly-P5Q was introduced by the oxidation of Poly-Dimethoxypillar[5]arene. A Friedel-Crafts reaction was employed to prepare a novel Poly-P5Q as organic cathode material for lithium-ion batteries. Abstract: In the recent years, organic electrode materials have attracted tremendous attention and becoming promising electrode candidates for the green and sustainable lithium-ion batteries. A novel hypercrosslinked Poly-Pillar[5]quinone (Poly-P5Q) polymer was prepared and applied as electrode material in Li-ion batteries. Poly-P5Q is the oxidized form of Poly-Dimethoxypillar[5]arene (Poly-DMP5A) which was obtained from the condensation of dimethoxypillar[5]arene and formaldehyde dimethyl acetal using Friedel-Crafts reaction. The prepared materials were characterized by 13 C solid state NMR, FTIR, SEM, EDX and TGA analysis. The Poly-P5Q cathode showed an initial discharge capacity up to 105 mAh g −1 whereas it retained 82.3% of its initial discharge capacity after 100 charge-discharge cycles at a current speed of 100 mA g −1 in the potential window between 1.75 to 3.25 V. In future, research in this direction will provide great insight for the development of novel polymers from various small organic molecules as a stable and high performance electrode materials for green lithium-ion batteries.
