Recycling Technologies for Cathode Materials from Spent Lithium Iron Phosphate Batteries: An Overview.
Review in Materials (Basel, Switzerland), 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
With the accelerated deployment of new energy vehicles and the global pursuit of carbon neutrality and carbon peaking goals, lithium iron phosphate (LFP) batteries have become a dominant technology in the energy storage market. The rapid expansion in their production and application has led to a surge in the number of spent LFP batteries, raising urgent concerns regarding resource recovery and environmental sustainability. This review provides a comprehensive overview of recycling technologies for spent LFP batteries, which are categorized into three major routes: (i) conventional metallurgical recycling, including pyrometallurgical and hydrometallurgical processes; (ii) direct regeneration strategies, such as electrochemical and solid-state approaches; and (iii) emerging green technologies, which leverage external fields or novel eco-friendly solvents to enhance recovery efficiency. The fundamental mechanisms, advantages, and limitations of each approach are systematically analyzed and compared. Finally, we also discuss current challenges and future directions for developing high-efficiency, low-cost, and environmentally benign recycling systems. These technological advances are expected to not only promote resource circularity and reduce ecological burdens but also provide a solid foundation for the sustainable evolution of the lithium-ion battery industry.
