چکیده
Abstract Electrode architectures significantly influence the electrochemical performance, flexibility, and applications of lithium‐ion batteries (LiBs). However, conventional bar coating for fabricating electrodes limits addition customized architecture or patterns. In this study, as a novel approach, patterns are integrated into through large‐scale roll‐to‐roll (R2R) flexographic printing. Additionally, flexible, recyclable, biodegradable paper innovatively used printing substrate during LiBs manufacturing, which exhibited superior printability. Moreover, is modified with thin‐layer Al 2 O 3 to function separator in printed LiB. The ‐coated enables an admirable wettability printing, excellent mechanical properties high‐speed R2R outstanding thermal stability safe stable operation LiBs. assembled cells exhibit nearly 100% discharge capacity retention after 1000 cycles at C rate performance. This work inspires future microbatteries manufacturing high‐resolution designs.

Ultrathin high-resolution flexographic printing using nanoporous stamps
Since its invention in ancient times, relief printing, commonly called flexography, has been used to mass-produce artifacts ranging from decorative graphics to printed media. Now, higher-resolution flexography is essential to manufacturing low-cost, large-area printed electronics. However, because of contact-mediated liquid instabilities and spreading, the resolution of flexographic printing us...

Direct patterning of gold nanoparticles using flexographic printing for biosensing applications
In this paper, we have presented the use of flexographic printing techniques in the selective patterning of gold nanoparticles (AuNPs) onto a substrate. Highly uniform coverage of AuNPs was selectively patterned on the substrate surface, which was subsequently used in the development of a glucose sensor. These AuNPs provide a biocompatible site for the attachment of enzymes and offer high sensi...
