Selective catalysis remedies polysulfide shuttling in lithium-sulfur batteries [PDF]

open access: yesAdvanced Materials, 2020
Abstract The shuttling of soluble lithium polysulfides between the electrodes leads to serious capacity fading and excess use of electrolyte, which severely bottlenecks practical use of Li-S batteries. Here selective catalysis is proposed as a fundamental remedy for the consecutive solid-liquid-solid sulfur redox reactions. The proof-of-concept
