TL;DR: In this article, an artificial solid electrolyte interphase (aSEI) with a specific set of mechanical characteristics is designed, which encloses Si within a TiO2 shell thinner than 15 nm.

TL;DR: An overview of the fundamental understandings of solid electrolyte interphase (SEI) formation, conceptual models, and advanced real-time characterizations of LMI are presented and practical challenges in competing with graphite and silicon anodes are outlined.

TL;DR: LiMn2O4 and its derivatives with cubic lattice symmetry on average are discussed in this paper, where the authors show reversible hybrid anionand cation-redox 0.5O4 degradation.

TL;DR: Li et al. as discussed by the authors developed a roll-to-roll mechanical prelithiation method and successfully pre-lithiated Sn foil, Al foil and Si/C anodes, which exhibited an increased coulombic efficiency from 20% to 94% and achieved 200 stable cycles in LiFePO4/LixSn full cells at ∼2.65 mA h cm−2.

TL;DR: It is shown that graphite can either appear superlithiophilic or lithiophobic, depending on the local redox potential, which enables new fabrication technology for Li–graphite composite with a controllable Li-metal/graphite ratio and presents great promise for the mass production of Li-based anodes for use in high-energy-density batteries.
