Here we report a family of Li-excess Mn-rich cathodes that integrates rocksalt- and polyanion-type structures. Following design rules for cation filling and ordering, we demonstrate the bulk incorporation of polyanion groups into the rocksalt lattice. This integration bridges the two primary families of lithium-ion battery cathodes—layered/spinel and phosphate oxides—dramatically enhancing the cycling stability of disordered rocksalt cathodes with 4.8 V upper cut-off voltage. The cathode exhibits high gravimetric energy densities above 1,100 Wh kg−1 and >70% retention over 100 cycles. This study opens up a broad compositional space for developing battery cathodes using earth-abundant elements such as Mn and Fe.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"3 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142042635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process by which cation solvation conforms to the interfacial field to form interphases remains unclear. Here we examine the synergistic effects of external and intramolecular fields on accommodating Li+ solvates to the Li-metal anode, leading to dielectric-mediated transfer dynamics on the interface. At charged interfaces, cation–anion pairs arrange in a periodic oscillatory distribution. A low-oscillation amplitude exacerbates the electrolyte decomposition and increases surface impedance. We propose a dielectric protocol that maintains cation–anion coordination with a high oscillation amplitude at the interfaces, addressing these issues. Accordingly, we demonstrate a Li-metal pouch cell with an energy density of 500 Wh kg−1 at the Ah level using an ultra-lean electrolyte (1 g Ah−1). Our study offers insights into solid/liquid interfaces that are crucial in advancing battery technologies. Cation solvation in batteries is well understood in bulk solutions but less so at electrode/electrolyte interfaces. This study reveals how external and intramolecular fields affect Li-ion solvation, proposing a dielectric protocol to enhance cation–anion coordination and improve performance in Li-metal pouch cells.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"9 10","pages":"1285-1296"},"PeriodicalIF":49.7,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142022035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they suffer from fast capacity decay and low Coulombic efficiency in carbonate electrolytes because the organic solid electrolyte interphase (SEI) strongly bonds to the alloys, leading to cracks of both SEI and alloying particles, which allows electrolyte penetration and forms new SEI during lithiation–delithiation cycles. Using nano-sized alloying anodes can enhance the cell cycle life but also reduces the battery calendar life and increases the manufacturing costs. Here we significantly improved the cycle performance of micro-sized Si, Al, Sn and Bi anodes by developing asymmetric electrolytes (solvent-free ionic liquids and molecular solvent) to form LiF-rich inorganic SEI, enabling 90 mAh μSi||LiNi0.8Mn0.1Co0.1O2 and 70 mAh Li3.75Si||SPAN pouch cells (areal capacity of 4.5 mAh cm−2; N/P of 1.4) to achieve >400 cycles with a high capacity retention of >85%. The asymmetric electrolyte design forms LiF-rich interphases that enable high-capacity anodes and high-energy cathodes to achieve a long cycle life and provide a general solution for high-energy Li-ion batteries.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"23 1","pages":""},"PeriodicalIF":56.7,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142007635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
