主 题：direct ink writing efficient polysulfides conversion Li-S batteries metal-based electrocatalysts
摘 要：Thanks to the significantly higher energy density compared with universal commercialized Li-ion batteries,lithium–sulfur(Li–S)batteries are being investigated for use in prospective energy storage ***,the inadequate electrochemical kinetics of reactants and intermediates hinder commercial *** limitation results in substantial capacity degradation and short battery lifespans,thereby impeding the battery s power ***,the capacity attenuation induced by the undesirable shuttle effect further hinders their *** effort has been invested in developing electrocatalysts to fix lithium polysulfides and boost their conversion *** the conventional process,the planar electrodes are prepared by slurry-casting,which limits the electron and ion transfer paths,especially when the thickness of the electrodes is relatively *** with traditional manufacturing methods,direct ink writing(DIW)technology offers unique advantages in both geometry shaping and rapid prototyping,and even complex three-dimensional structures with high sulfur ***,this review presents a detailed description of the current developments in terms of Li–S batteries in DIW of metal-based electrocatalysts.A thorough exploration of the behavior chemistry of electrocatalysis is provided,and the adhibition of metal-based catalysts used for Li–S batteries is summarized from the aspect of material usage and performance ***,the working principle of DIW technology and the requirements of used inks are presented,with a detailed focus on the latest advancements in DIW of metal-based catalysts in Li–S battery *** challenges and prospects are discussed to guide their future development.
