The minimization of irreversible active lithium loss stands as a pivotal concern in rechargeable lithium batteries, particularly in the context of grid-storage applications, where achieving the utmost energy density over prolonged cycling is imperative to meet stringent demands, notably in terms of life cost. Departing from conventional methodologies advocating electrode prelithiation and/or electrolyte additives, this study proposes a new paradigm: the integration of a designer lithium reservoir (DLR) featuring lithium orthosilicate (Li4 SiO4 ) and elemental sulphur...
