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

Deformable batteries with compressive and impact-buffered abilities are essential for enhancing battery safety. However, existing compressible electrodes often face limited physical deformation and generate high stress, leading to package bulges of batteries. Here, we present a metamaterial-inspired design to develop negative Poisson's ratio (NPR) structural electrodes using a directional freezing 3D printing-assisted strategy. This approach incorporates both macroscopic NPR structures and microscopic directional porous structures, which enhances ion transport, improves compressibility and provides impact resistance, effectively preventing package bulges during compression. Consequently, the electrodes demonstrate a high 50% compressible deformation and recover their original state even after 50 cycles of 25% compression. The 3D-printed lithium iron phosphate cathodes deliver a high average specific capacity of 153 mAh/g over 100 cycles and exhibit outstanding rate capability. Furthermore, the assembled full cell maintains both excellent compressibility and impact-buffered resistance, highlighting its potential applications. This innovative design of NPR metamaterial-structured electrodes provides a universal platform for developing the next generation of impact-buffered, compressible structural batteries.
