Abstract

Electrostatic dielectric capacitors with ultrahigh power densities are sought after for advanced electronic and electrical systems owing to their ultrafast charge-discharge capability. However, low energy density resulting from low breakdown strength and suppressed polarization still remains a daunting challenge for practical applications. We propose a microstructural strategy with dendritic nanopolar (DNP) regions self-assembled into an insulator, which simultaneously enhances breakdown strength and high-field polarizability and minimizes energy loss and thus markedly improves energy storage performance and stability. For illustration, in this study, we achieved a high energy density of 215.8 joules per cubic centimeter with an efficiency of 80.7% at a high electric field of 7.4 megavolts per centimeter in a DNP structure–designed PbZr_0.53Ti_0.47O₃-MgO film. The proposed strategy is generally applicable for development of high-performance dielectric microcapacitors.

树枝状纳米极设计的超高电容储能

具有超高功率密度的静电介质电容器由于具有超快的充放电能力，在先进的电子和电气系统中受到追捧。然而，低击穿强度和抑制极化导致的低能量密度仍然是实际应用中一个令人生畏的挑战。我们提出了一种树突状纳米极（DNP）区域自组装成绝缘体的微观结构策略，该策略同时提高了击穿强度和高场极化率，最大限度地减少了能量损失，从而显着提高了储能性能和稳定性。例如，在本研究中，我们在DNP结构设计的PbZr 0.53 Ti 0.47 O 3 -MgO薄膜中实现了215.8焦耳/立方厘米的高能量密度，在7.4兆伏/厘米的高电场下效率为80.7%。所提出的策略一般适用于高性能介电微电容器的开发。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
