A high-entropy engineering on sustainable anionic redox Mn-based cathode with retardant stress for high-rate sodium-ion batteries.

Manganese-based (Mn-based) layered oxides have emerged as competitive cathode materials for sodium-ion batteries (SIBs), primarily due to their high energy density, cost-effectiveness, and potential for mass production. However, these materials often suffer from irreversible oxygen redox reactions, significant phase transitions, and microcrack formation, which lead to considerable internal stress and degradation of electrochemical performance. This study introduces a high-entropy engineering strategy for P2-type Mn-based layered oxide cathodes (HE-NMCO), wherein a multi-ingredient cocktail effect strengthens the lattice framework by modulating the local environmental chemistry.

Transcriptomic analysis reveals potential crosstalk genes and immune relationship between triple-negative breast cancer and depression.

TNBC, the most aggressive form of breast cancer, lacks accurate and effective therapeutic targets. Immunotherapy presents a promising approach for addressing TNBC. Anxiety and depression are frequently concurrent symptoms in TNBC patients.

Stabilized Oxygen Vacancy Chemistry toward High-Performance Layered Oxide Cathodes for Sodium-Ion Batteries.

Anionic redox has emerged as a transformative paradigm for high-energy layered transition-metal (TM) oxide cathodes, but it is usually accompanied by the formation of anionic redox-mediated oxygen vacancies (OVs) due to irreversible oxygen release. Additionally, external factor-induced OVs (defined as intrinsic OVs) also play a pivotal role in the physicochemical properties of layered TM oxides. However, an in-depth understanding of the interplay between intrinsic and anionic redox-mediated OVs and the corresponding regulation mechanism of the dynamic evolution of OVs is still missing.

Thgraphene with High Polysulfide Anchoring Ability and Catalytic Performance for Advanced Na-S Batteries: A First-Principles Study.

The sodium-sulfur (Na-S) batteries, with advantages such as high energy density, high specific capacity, and low cost, have attracted significant attention in the field of rechargeable batteries in recent years. However, their practical application still faces many challenges. In this study, we employ first-principles calculations to investigate the performance of a 2D carbon allotrope, thgraphene, as an anchoring material in Na-S batteries.
