Abstract Spin-engineering with electrocatalysts have been exploited to suppress the “shuttle effect” in Li–S batteries. Spin selection, spin-dependent electron mobility and spin potentials activation barriers can be optimized as quantum exchange interactions leading a significant reduction of electronic repulsions orbitals catalysts. Herein, we anchor MgPc molecules on fluorinated carbon nanotubes (MgPc@FCNT), which exhibits single active Mg sites axial displacement. According density...

Abstract Catalytic conversion of lithium polysulfides (LiPSs) is a crucial approach to enhance the redox kinetics and suppress shuttle effect in lithium–sulfur (Li–S) batteries. However, roles typical heterogenous catalyst cannot be easily identified due its structural complexity.

Large Language Models (LLMs) enhanced with external contexts, such as through retrieval-augmented generation (RAG), often face challenges in handling imperfect evidence. They tend to over-rely on knowledge, making them vulnerable misleading and unhelpful contexts. To address this, we propose the concept of context-robust LLMs, which can effectively balance internal knowledge context, similar human cognitive processes. Specifically, LLMs should rely context only when lacking identify...
