1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The internal heat generation and the growth of lithium dendrites have raised severe safety issues in lithium metal batteries (LMBs), which significantly hinder their widespread adoption. Therefore, it is critical to develop intelligent separators to improve the security and performance of LMBs. Here, we engineer a self-repairing polyetherimide (PEI)-functionalized polyamide-imide (PAI@PEI) nanofiber separator with a thermal-gated function, in which the thermoplastic PEI core has an automatically thermal shutdown function via intelligent closure of apertures under high temperature, while the thermosetting PAI shell can drive the remodeling of PEI to restore its apertures. The PAI@PEI separator showcases the topmost aperture-closing temperature of 400 °C compared to the cutting-edge separators that typically have an aperture-closing temperature below 200 °C. Morphological characterization confirms that the PAI@PEI separator with a closed aperture can recover its apertures at 350 °C, endowing the PAI@PEI separator with a unique self-repairing function to enhance the longevity and safety of LMBs. Meanwhile, density functional theory calculations reveal that the polar amide and imide groups in PAI@PEI separator, both before and after aperture restoration, can efficiently facilitate Li-ion dissociation and transportation for suppressing lithium dendrite growth. As a result, the aperture-restored PAI@PEI separator (R-PAI@PEI) demonstrates significantly improved overall electrochemical performance. Specifically, the R-PAI@PEI-based Li||Li cell exhibits an exceptional Li-ion transference number of 0.71 and an excellent cycling stability at 1 mA cm
