Summary: Although Li-CO2 batteries are highly regarded for their high energy density and carbon utilization, their cathodic reaction mechanism is not well understood. Previous studies have lacked evidence of carbon formation and the calculated redox potential is inconsistent with the working potential. The authors propose that the observed reaction is caused by the participation of O2 and H2O, leading to a higher working potential.

Summary: We investigated the structural and electrochemical properties of Li-Ti-O (LTO) and CNT-added LTO for anode material in secondary Li-ion batteries. The study focused on elucidating the effects of microstructural evolution in LTO and the addition of CNT on battery functionality. The results showed that the degradation in electrochemical property of LTO is mainly due to an increase in Li content, and the addition of CNT can greatly increase Li capacity while not significantly changing the LTO composition and redox kinetics. This suggests that surface engineering through CNT addition is a promising way to improve the performance of LTO-based anode material.

Summary: First-principles calculations were performed to investigate WN MXenes as potential cathode catalysts for Li-O-2 batteries. The results show that the oxygen functionalized surfaces of WN MXenes can lower the overpotentials of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) due to their ability to bind with Li and promote electron transfer. Reducing the atomic layers of WN MXenes can further lower the overpotentials.
