High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Research on the electronic and chemical structure study of Zinc oxide/Silicon carbide heterojunction [PDF]
, 2016 氧化锌（ZnO）半导体材料由于禁带宽度大、激子能量高等诸多优点呈现出良好的紫外光电特性。然而由于电导率较低、载流子浓度不高、稳定性较差等原因，p型ZnO材料的制备仍然面临较大的挑战，直接影响了ZnO基器件的性能。因此寻找合适衬底制备高质量ZnO异质结具有重要的意义。而碳化硅（SiC）由于热稳定性高、化学性能稳定、热导率高、电子饱和和漂移速度快等特点，与ZnO的晶格失配度小（约5%），在SiC衬底上能够获得高质量的ZnO异质结且应用在光电器件上。 本论文研究不同生长方式下制备的ZnO ...
