Li-air chemistry inspired electrodialysis for direct lithium carbonate production from seawater.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 global shift to renewable energy has intensified demand for lithium-ion batteries. Conventional lithium sources and extraction methods-such as brine evaporation and ore roasting-are time- and resource-intensive, geographically constrained, and environmentally damaging, underscoring the need for more sustainable resources and extraction strategies. Here we report an electrodialysis-based approach for direct lithium carbonate extraction from seawater, using ambient carbon dioxide as the carbon source. The method integrates a solid-state lithium-conducting membrane with Li-air chemistry, enabling lithium enrichment and carbonate formation in a single step without added precipitants. The Li-air configuration imparts intrinsic ion selectivity via thermodynamically driven displacement reactions. Experimental results confirm the production of lithium carbonate (93.8% purity) with an applied voltage below 2 V, while reducing chemical input and energy consumption compared to conventional processes. This work has the potential to provide a low-impact route for accessing lithium resources and contributes to the sustainability of future battery supply chains.
