For the effective implementation of all-solid-state batteries (ASSBs), the progress of dry electrode technology is essential. Considering the urgent challenges posed by global warming, advancing affordable ASSBs is crucial for reliable and sustainable electrochemical energy conversion and storage systems. Despite the substantial progress in research on solid electrolytes, ASSBs continue to face fundamental challenges, including high manufacturing costs, considerable environmental impact, and insufficient interfacial stability. The dry electrode processing methodology presents a highly promising alternative to conventional wet electrode fabrication techniques, effectively addressing these limitations while facilitating scalable production capabilities. Although research on dry-electrode-based ASSBs has gained significant traction in recent years, the overall challenges are recognized as intricate due to the presence of multiple electrode components with diverse requirements and limitations. For the comprehensive review, the dry processing approach is systematically examined from the perspective of materials science and electrode processing. An electrode-component-level framework is adopted as well. Furthermore, crucial technical barriers are identified, and prospective research directions for the advancement of solid-state battery technology are delineated.
对于全固态电池（ASSB）的有效实施，干电极技术的进展至关重要。考虑到全球变暖带来的紧迫挑战，推进价格合理的全固态电池对于可靠且可持续的电化学能量转换和存储系统至关重要。尽管在固体电解质研究方面取得了重大进展，但全固态电池仍面临着一些基本挑战，包括高昂的制造成本、相当大的环境影响以及界面稳定性不足。干电极加工方法为传统湿电极制造技术提供了一种极具前景的替代方案，有效地解决了这些限制，同时具备可扩展的生产能力。尽管近年来基于干电极的全固态电池研究已获得显著关注，但由于存在多种具有不同要求和限制的电极组件，整体挑战仍被认为十分复杂。为了进行全面综述，从材料科学和电极加工的角度对干法加工方法进行了系统研究。同时还采用了电极组件级框架。此外，确定了关键技术障碍，并描绘了全固态电池技术进步的前瞻性研究方向。
