Abstract Developing efficient and durable single‐atom catalysts is vitally important for the sulfur redox reaction (SROR) in Li−S battery, while it remains enormous challenging. Herein, undercoordinated Ni−N 3 moieties anchored on N,S‐codoped porous carbon (Ni−NSC) obtained to enhance SROR. The experiments theoretical calculations indicate that symmetry‐breaking charge transfer Ni catalyst originates from tuning effect of atoms mediated moieties, which can both facilitate chemical adsorption by formation N−Ni⋅⋅⋅S n 2− , achieve a rapid conversion polysulfides because enhanced electron transfer. As results, Ni−NSC based battery delivers very high initial reversible capacity (1025 mAh g −1 at 1 C), as well outstanding cycling‐stability 2400 cycles 2 C C, respectively. Noteworthy, areal reach 7.8 cm −2 0.05 retention 4.7 after 100 0.2 with loading 5.88 mg . This work provides profound insight rational optimizing microscopic electronic density active site promoting SROR metal‐sulfur batteries.

Lightweight Materials for High Energy Density Lithium–Sulfur Batteries

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 28, 2025

Abstract At present, electronic devices such as electric vehicles and mobile phones have increasing requirements for battery energy density. Lithium–sulfur batteries (LSBs) a high theoretical density are considered potential choice realizing the next generation of (2600 W h kg −1 ) batteries. However, actual LSBs is much lower than due to poor conductivity sulfur, serious LiPSs shuttle, low sulfur utilization, so on. Many lightweight materials characterized by surface area designability. The reasonable design modify can reduce proportion inactive substances optimizing electrochemical performance, which crucial improving LSBs. few reviews discuss effect on from perspective whole system. Herein, application in six aspects: liquid electrolyte, solid cathode, anode, separator, current collector discussed. significance use further improvement summarized prospected.
