However, the longevity of these Mn-based materials remains a crucial challenge that hampers their adoption in grid-scale applications. To address this issue, the composite-structure outside of grain (CSOG) strategy integrated with layered/olivine structures is proposed for enhancing the stability of crystal structure, interfacial chemistry, and electrochemical cycling behaviors of Mn-LLOs. A series of cutting-edge microscopic and synchrotron techniques present the CSOG strategy that initiates the intensified particle surface, stable P−O bonding for layered structure, and robust electrode-electrolyte interphase. This multi-faceted reinforcement effectively bolsters interfacial stability for both pristine and electrochemical cycling. As a result, the Mn-based CSOG cathodes realize superior capacity retention over 1000 cycles with capacity decay of ∼0.009 % per cycle in pouch cells. Crucially, enhanced interfacial behaviors in the CSOG cathodes inhibit elemental dissolution and deposition of Mn onto the anode and result in a ∼39 % improvement in thermal stability compared to pristine Mn-LLOs. This innovative CSOG concept opens new avenues for designing highly stable Mn-based cathode materials, accentuating their potential for grid-scale EES applications.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"76 ","pages":"Article 104151"},"PeriodicalIF":18.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143570206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a co-doping strategy with lithium and niobium is proposed to enhance the structural stability at both room-temperature (RT) and low-temperature (LT) over extended cycles.
