随着高性能电子产品的发展，与热失控相关的安全问题应得到更多的考虑。以前的策略通常受到关闭效率和关闭温度的限制。在这里，我们提出了一种MXene超级电容器，它装载了一种智能热响应电解质，以科普高温下的热失控。在室温下，含有聚（N-异丙基丙烯酰胺-甲基丙烯酸缩水甘油酯）（PNGM）的电解液中的离子可以自由迁移，器件可以正常工作。智能电解质系统形成疏水网络，有效抑制离子迁移，实现高温下的热关断。该电解质体系在升温过程中表现出不同的电化学性能，在85°C时达到近90%的容量抑制。所提出的智能电解质系统通过实现主动保护策略为当前电子设备的热安全提供了一个有前途的解决方案
With the growth of high performance electronics, more consideration should be given to the safety issues associated with thermal runaway. Previous strategies have often been limited by shutdown efficiency and shutdown temperature. Here, we present a MXene supercapacitor loaded with a smart thermally responsive electrolyte to cope with thermal runaway at high temperatures. At room temperature, the ions in the electrolyte containing the poly (N-isopropylacrylamide-co-glycidyl methacrylate) (PNGM) can migrate freely and the devices.can operate normally. The smart electrolyte system forms a hydrophobic network that effectively inhibits ion migration to achieve thermal shutdown at high temperatures. The electrolyte system exhibits different electrochemical properties during heating up, reaching nearly 90% capacity suppression at 85°C. The proposed smart electrolyte system provides a promising solution to the thermal safety suitable for current electronic devices by achieving a proactive protection strategy
