  • Li intercalation of MoS2 induces a transition from the insulating H-phase to the metallic T-phase, with a sharp boundary in between. Here the authors stabilize the intermediate phase in twisted bilayer MoS2, by leveraging the Moiré potential which facilitates fast Li diffusion and uniform intercalation.

  • Operation of lithium batteries at high, non-uniform temperatures can lead to safety issues, but the effects of localized high temperatures are difficult to probe. Here the authors use micro-Raman spectroscopy to show that local-temperature hotspots can induce lithium metal growth and trigger circuit shorting.

  • Achieving extremely fast charging while maintaining high energy density remains a challenge in the battery field. Here the authors conceptualize a porous current collector that successfully reduces the effective Li+ transport distance by half, quadrupling the diffusion-limited C-rate capability without compromising battery energy density.

  • Fast-charging is highly desired for lithium-ion batteries but is hindered by potential hazardous lithium plating and the associated parasitic reactions. Here, the authors report a nondestructive differential pressure sensing method for early detection and mitigation of lithium plating in fast-charging batteries.

  • Introduction of guest species into archetype materials lays out a foundational pathway for creating new materials classes with desired functionalities. This Review discusses two main strategies of such applied to 2D layered materials: gating, where the guest species rest on the surface, and intercalation, where the guest species are incorporated into the host lattice.
