新设备创造了存储介电能量的最高记录

[Material Search] Science and Technology Daily News (Reporter Jin Feng) The reporter learned from Nanjing University of Aeronautics and Astronautics on May 13 that the school's scientific research team has joined hands with Chinese and foreign scholars to innovatively develop a new nanacomptite thin-film energy storage device with device with device with device with High Energy storage density, with energy storage density up to 215.8 jog/cubic centimeter, setting a new international record用于介电能量存储的密度。相关论文已发表在科学上。刘Yajing（Liu Yajing）是Nanjing Aeronautics and Actronautics University在Nanjing University的第一个设置纸张和博士后的人，目前介绍了当前使用的能源存储设备等稳定性。它们适合使用可以立即发布高能电力的方案，并且在Pacemaker，电动车辆，电网，可再生能源的田野中具有广泛的应用前景等等。“但是很长一段时间以来，介电材料的能量存储显着低于基本的储能技术，例如锂电池，锂电池已成为将限制限制的瓶颈。” Liu Yajing introduced, "When the electric field applied to dielectric energy storage devices is very strong, the insulation of device materials is destroyed, and electrons flow in large quantities as they are out of control, forming conductive paths, resulting in a sharp increase in the current, which can cause short circus or device damage. -This study, the team innovative adopted the "Dendritic Nanopolar" design approach to the broad bandgap insulated dielectric产生纳米复合膜模型的孕妇。“在结构的结构中，宽带隔离的介电材料的带隙比传统材料宽，因此它对高压和高温更具耐药性，并且具有更强的能量存储性能。树突结构E可以阻止电梁在电损伤期间的击穿路径，这更有可能抵抗高升压电压的设备。刘Yajing说。该团队建造了一个介电能量存储装置，长度为5毫米，厚度为100纳米。在7.4 mW/cm的电场下，能量存储密度可以达到215.8慢跑/立方厘米的215.8 JOG/立方厘米，可以使载量存储密度的国际最高记录损失。在零高于零的170度摄氏度和1010次疲劳测试的温度下，“这项研究为开发高性能的储能设备提供了创新的方法。
