Dry processing emerges as a cost-effective technique for achieving high material loading in the field of lithium-ion battery fabrication. Nevertheless, insight into the role of current collectors in this process is still scarce. Herein, a set of dry-processed electrodes with three different current collectors is accordingly prepared and comprehensively studied. This work novelly reveals that the current collectors exhibit significant influence on the interface adhesion strength and the electron conductivity, which leads to difference in the mechanical strength and electrochemical performance of dry-processed electrodes. Consequently, it is recommended that carbon-coated current collector is preferred for dry-processed high energy density lithium-ion battery electrodes.
干法工艺作为一种在锂离子电池制造领域实现高材料负载的经济高效技术而出现。然而，对于集流体在该过程中的作用的了解仍然很少。在此，相应地制备并全面研究了一组具有三种不同集流体的干法电极。这项工作新颖地揭示了集流体对界面粘附强度和电子传导率有显著影响，这导致干法电极在机械强度和电化学性能上存在差异。因此，建议对于干法高能量密度锂离子电池电极，优先选择碳包覆集流体。
