Summary: Lithium sulfur (Li-S) batteries hold great promise for next generation electronics and electrical vehicles due to their high theoretical capacity and energy density. However, the development of Li-S batteries is hindered by the shuttle effect and sluggish conversion kinetics of lithium polysulfides (LiPSs). This review provides a systematic analysis of the adsorption and catalytic mechanism in Li-S chemistry, discussing the role of metal oxides (MOs) as efficient catalysts and proposing oxygen vacancies and heterostructure engineering as effective strategies to improve the sluggish adsorption-diffusion-conversion process. The challenges and prospects of MOs electrocatalysts in Li-S batteries are also discussed.

Summary: Li1.17Na0.02Mn0.54Ni0.13Co0.13O2 (PN-LMNCO) is prepared through surface phase structure controlling and ion doping to address the rapid capacity fading and voltage decay issues of Li-rich Mn-based cathode materials. The introduction of lithium deficiencies induces surface phase transformation and forms an in-situ spinel surface conversion film, effectively inhibiting structure degradation during charge/discharge. Additionally, sodium doping increases spacing between Li layers, improving the rate capacity. The PN-LMNCO exhibits high initial coulombic efficiency (91.2%), retains 94.7% discharge specific capacity after 200 cycles, and maintains good discharge capacity (214 mA h g(-1)) at a high current rate of 5 C. This work is important for the development of high-energy density lithium-ion batteries for electric vehicles.

Summary: To improve the electrochemical properties of lithium-sulfur batteries, this study proposes a rational strategy of tuning the d-band of catalysts through the introduction of Fe into in situ grown Ni2P on rGO, resulting in NiFeP/rGO composites. The incorporation of Fe improves the metallic conduction of Ni2P and elevates the d-band center of NiFeP, effectively facilitating charge transfer and weakening the S-S bonds of polysulfides. As a functional interlayer, NiFeP/rGO composites not only promote the interaction between polysulfides and NiFeP but also accelerate the conversion of polysulfides. The high-efficiency NiFeP/rGO electrocatalyst demonstrates the availability of the d-band regulating strategy for lithium-sulfur batteries, providing insights into the redox reaction of LiPSs at the molecular or atom level.
