Dielectric capacitors are fundamental components in electronic and electrical systems due to their high-rate charging/discharging character and ultrahigh power density. Film dielectrics possess larger breakdown strength and higher energy density than their bulk counterparts, holding great promise for compact and efficient power systems. In this article, we review the very recent advances in dielectric films, in the framework of engineering at multiple scales to improve energy storage performance. Strategies are summarized including atomic-scale defect control, nanoscale domain and grain engineering, as well as mesoscale composite design. Challenges and remaining concerns are also discussed for further performance improvement and practical application of dielectric films.

高性能电容性储能的介电膜：多尺度工程。
介电电容器由于其高速率充电/放电特性和超高功率密度而成为电子和电气系统中的基本组件。薄膜电介质比大体积的同类电介质具有更大的击穿强度和更高的能量密度，为紧凑高效的电源系统提供了广阔的前景。在本文中，我们将在多种规模的工程框架中回顾介电膜的最新进展，以改善储能性能。总结了包括原子级缺陷控制，纳米级域和晶粒工程以及中尺度复合材料设计在内的策略。还讨论了挑战和仍然存在的问题，以进一步提高电介质膜的性能和实际应用。
