Type: article

Abstract: Lithium-Ion Batteries In article number 2507185, Jingping Hu, Huijie Hou, and co-workers report an upcycling strategy that turns battery waste into a high-value, powerful energy source. The image features a high-speed race between two concept cars, symbolizing the performance leap of battery cathode materials. The leading orange car, labeled “LMFP”, represents our upcycled LiMnxFe1−xPO4 material, showcasing its superior voltage and capacity. It is overtaking the blue car, which represents the conventional LiFePO4 (LFP) material. The glowing microscopic structures in the background depict the transformation from mixed spent cathodes into a homogeneously distributed, high-performance solid solution, which is the key to the enhanced energy density.
