Micro-nano energy recovery and storage integrated chip based on three-dimensional graphene and working method thereof

Abstract

The invention discloses a micro-nano energy recovery and storage integrated chip based on three-dimensional graphene and a working method thereof. The chip is composed of a base, a middle layer, a toplayer, a power generation positive electrode module, a power generation negative electrode module and a capacitor module, wherein the base, the middle layer and the top layer are arranged from the bottom to top in sequence, and the power generation positive electrode module, the power generation negative electrode module and the capacitor module are embedded in the three-layer structure. The power generation positive electrode module and the power generation negative electrode module are made of porous three-dimensional graphene internally containing positive electrode particles and negativeelectrode particles respectively, the particles collide and rub with the wall surface of the three-dimensional graphene when the chip is vibrated to generate positive and negative charges respectively, and the positive and negative charges are processed by a power supply management module and then power is supplied to the outside; the capacitor module is used for storing the electric energy converted from the vibration energy when the generated power is larger than the power supply power and supplying power outwards in a supplementary mode when the generated power is insufficient. Energy recovery and storage elements are integrated in the chip, so that power can be continuously supplied to the outside and surplus electric quantity can be stored. The chip is manufactured by adopting a micro-nano process, is small in size, and is suitable for mobile consumer electronic products and the internet of things and the like.
