TL;DR: Li et al. as discussed by the authors proposed a reversible Li-CO 2 battery system based on co-oxidization of the resulting carbon and Li 2 CO 3 using a Ru catalyst, which provides strong theoretical underpinning for developing flexible routes for both CO 2 fixation and energy storage.

TL;DR: In this article, Ru nanoparticles have been deposited on Super P carbon using a solvothermal method and the resulting material (Ru@Super P) has been employed as a cathode in Li-CO2 batteries.

TL;DR: Wang et al. as discussed by the authors studied the reaction mechanisms and electrochemistry in Li-air and Li-CO2 batteries and published more than 90 peer-reviewed papers on functional materials and energy storage systems such as lithium-ion batteries and lithium-air batteries.

TL;DR: Li et al. as mentioned in this paper showed that CO2 is released during the electrochemical decomposition of Li2CO3 while O2 is not detected throughout the whole process, and they further demonstrated that this degradation is caused by superoxide radicals, which are generated from Li 2CO3.

TL;DR: A new mechanism involving HO2- intermediate realizes the two-electron transfer through a single step, which significantly suppresses the superoxide-related side reactions and triggers a solution-based pathway that effectively reduces the voltage hysteresis.
