元素掺杂钠基层状氧化物正极稳定性研究进展
Advances in element doping for stabilizing sodium-based layered oxide cathodes
摘要
Abstract
Sodium-ion batteries(SIBs)have broad application prospects in the field of large-scale en-ergy storage.Layered oxide cathodes(LOCs),due to low cost,high energy density,and mature prepa-ration process,have become ideal cathode materials for SIBs.However,in practical applications,LOCs faced many issues such as irreversible phase transitions,migration and dissolution of metal cat-ions,and severe interfacial side reactions,which led to the degradation of battery performance.In re-sponse to these challenges,researchers carried out extensive work and made remarkable progress es-pecially in microscopic local electronic regulation.A detailed summary of the scientific issues,that ur-gently need to be addressed regarding LOCs,was provided,the research advancements in these fields were outlined in recent years,the mechanism of how the regulation of local electronic structure af-fects the stability of LOCs was further explored,and aiming to offer valuable insights for improving the stability of SIBs cathode materials,thereby promoting the development and application of SIBs.关键词
