Laser-Constructing 3D Copper Current Collector with Crystalline Orientation Selectivity for Stable Lithium Metal Batteries

ENERGY & ENVIRONMENTAL MATERIALS 2024年第6期7卷 129-139页

The practical application of lithium (Li) metal anodes in high-capacity batteries is impeded by the formation of hazardous Li dendrites. To address this challenge, this research presents a novel methodology that combines laser ablation and heat treatment to precisely induce controlled grain growth within laser-structured grooves on copper (Cu) current collectors. Specifically, this approach enhances the prevalence of Cu (100) facets within the grooves, effectively lowering the overpotential for Li nucleation and promoting preferential Li deposition. Unlike approaches that modify the entire surface of collectors, our work focuses on selectively enhancing lithiophilicity within the grooves to mitigate the formation of Li dendrites and exhibit exceptional performance metrics. The half-cell with these collectors maintains a remarkable Coulombic efficiency of 97.42% over 350 cycles at 1 mA cm(-2). The symmetric cell can cycle stably for 1600 h at 0.5 mA cm(-2). Furthermore, when integrated with LiFePO4 cathodes, the full-cell configuration demonstrates outstanding capacity retention of 92.39% after 400 cycles at a 1C discharge rate. This study introduces a novel technique for fabricating selective lithiophilic three-dimensional (3D) Cu current collectors, thereby enhancing the performance of Li metal batteries. The insights gained from this approach hold promise for enhancing the performance of all laser-processed 3D Cu current collectors by enabling precise lithiophilic modifications within complex structures.

Trichoderma viride F7 improves peanut performances while remediating cadmium-contaminated soil with microplastics

引用

Pedosphere 2024年第5期34卷 971-980页

作者： Xin SONG Jianpeng JIN Hongliang YIN Tingjuan WANG Haiying ZONG Fangli WANG jun LIU Xiaoli huang Bin WANG chao CHAI Zhi LI Dongsheng LIU Xuexia WANG Ningning SONG School of Resources and Environment Qingdao Agricultural University Central Laboratory Qingdao Agricultural University Institute of Soil Fertilizer and Agricultural Water Saving Xinjiang Academy of Agricultural Sciences Institute of Plant Nutrition and Resources Beijing Agricultural Forestry Academy Sciences

Microplastics(MPs) and cadmium(Cd) in soil have serious negative impacts on plant growth. As a bioremediator, Trichoderma viride may modulate the impacts of MPs and/or Cd on plant growth and heavy metal uptake. In this study, T. viride F7 was used to treat Cd-contaminated soil with and without the presence of polylactic acid MPs to investigate its effects on peanut growth, Cd uptake efficiency, and soil properties. Results showed that F7 increased soil pH,dissolved organic carbon, cation exchange capacity, microbial biomass nitrogen, and microbial biomass carbon, which resulted in increases of 2.10%–19.83% in peanut biomass and mitigated the negative effects of MPs and Cd on peanut growth. Trichoderma viride F7 reduced the soil bioavailable Cd and plant Cd concentrations by 16.68%–34.20% and 5.37%–25.84%, respectively. Regression path analysis showed that F7 could improve peanut performances by altering soil properties and reducing peanut Cd concentrations in MP-Cd-contaminated soil. Soil fungal community analysis indicated that the microbial community was altered via F7 inoculation, which antagonized Fusarium and promoted peanut growth. This study reveals the mechanisms of F7 in mitigating Cd contamination in the soil with the presence of MPs, which provides new ideas for managing MP-heavy metal-contaminated soil and improving soil health.
