Lithium-sulfur batteries are promising alternative to Li-ion batteries owing to high theoretical gravimetric capacity (1675 mAh/g) and low cost of elemental sulfur. However, Li-S batteries suffer from rapid capacity fading largely due to shuttling of various polysulfide intermediates in solution. Here we present our studies on the effect of incorporation of redox-active anthraquinone-based polymers in bulk sulfur cathodes on cycling of Li-S batteries. Through electrochemical characterization and post-test analysis, the role of redox-active polymers in bulk sulfur cathodes is proposed.
