Capacitor electrode, preparation method and capacitor

Abstract

The embodiment of the invention provides a capacitor electrode, a preparation method and a capacitor. The capacitor electrode comprises at least two two-dimensional material sheet layers and at leastone carbon nano tube layer, wherein one carbon nano tube layer is arranged between every two two-dimensional material sheet layers. By use of the embodiment, the working frequency band can be improvedon the premise of guaranteeing capacitance density.

Description

technical field [0001] The embodiments of the present invention relate to the technical fields of micromachining and electrochemistry, and in particular to a capacitor electrode, a preparation method and a capacitor. Background technique [0002] With the rapid development of wearable devices and the Internet of Things, there are increasingly stringent requirements for the miniaturization and flexibility of electronic devices. For circuits in electronic equipment, although the volume of active transistors used for logic calculations has rapidly shrunk with the continuous verification of Moore's Law in the past few decades, other passive electronic components in the circuit, including resistors , capacitors and inductors, etc., but there is not much reduction in volume. Among the many passive components, the electrolytic capacitor is currently the largest single component on the circuit board. Its main function is to provide a capacitance of hundreds of microfarads or even ...
