AI Article Synopsis

  • Ammonia decomposition was studied using N-labelled ammonia and a lithium imide catalyst alongside mass spectrometry.
  • The findings revealed that nitrogen is released from the lithium imide catalyst's bulk during the reaction, while the actual decomposition happens at the catalyst's surface.
  • The results indicate that lithium imide actively decomposes ammonia rather than simply enhancing the performance of transition metal catalysts.

Article Abstract

Ammonia decomposition using N labelled ammonia was performed over a lithium imide catalyst with mass spectrometry. The results show that all the nitrogen is released from the bulk of the lithium imide catalyst during the ammonia decomposition reaction, but that the decomposition itself occurs at the catalyst surface; they also indicate that lithium imide decomposes ammonia and does not merely act as a promoter to transition metal catalysts.

Aromatic diimides such as naphthalene diimide (NDI) and pyromellitic diimide (MDI) are important building blocks for organic electrode materials. They feature a two-electron redox mechanism that allows for energy storage. Due to the smaller size of MDI compared to NDI its theoretical capacity is higher.

Enhancing both ionic conductivity and mechanical robustness remains a major challenge in designing solid-state electrolytes for lithium batteries. This work presents a novel approach in designing mechanically robust and highly conductive solid-state electrolytes, which involves ionic liquid-based cross-linked polymer networks incorporating polymeric ionic liquids (PILs). First, linear PILs with different side groups were synthesized for optimizing the structure.

ConspectusWater-in-salt electrolytes (WiSEs) are promising electrolytes for next-generation lithium-ion batteries (LIBs), offering critical advantages like nonflammability and improved safety. These electrolytes have extremely high salt concentrations and exhibit unique solvation structures and transport mechanisms dominated by the formation of ion networks and aggregates. These ion networks are central to the performance of WiSEs, govern the transport properties and stability of the electrolyte, deviating from conventional dilute aqueous or organic electrolytes.

Herein, a novel composite solid-state polymer electrolytes (CSEs) was regulated by introducing CoNi-MOF (Metal-organic framework) @NiPc (Nickel phthalocyanine) nanofiller (CMN) into PEO (polyethylene oxide) matrix. In this novel system, the NiPc uniformly wrapped around the surface of MOF through hydrogen bond bridging, avoiding the agglomeration of the MOF particles. The chemisorption between Ni in NiPc and the O atoms in the bis(triffuoromethanesulfonyl)imide anion (TFSI) restricted the mobility of the anions within the CSEs, which improved the release of Li ions from the NiPcLi.
