Radioactive three-dimensional nano-structure radiovolt electrochemical cell

Abstract

The invention relates to a radioactive three-dimensional nano-structure radiovolt electrochemical cell which comprises an anode, a cathode and electrolyte filling between the anode and the cathode, the anode is composed of a substrate electrode and a semiconductor three-dimensional nano-structure integrated on the surface of the substrate electrode, and at least one of the substrate electrode, the semiconductor structure and the cathode has radioactivity. The substrate electrode can be a radialized substrate electrode in which stable elements are replaced by radioactive isotopes of the same type; the semiconductors can be radialized semiconductors after stable elements are replaced by radioactive isotopes of the same type; the cathode can be a radialized cathode in which stable elements are replaced by radioactive isotopes of the same type. Rays generated by the radioactive isotope comprise alpha particles and beta particles, the alpha particles and the beta particles interact with a semiconductor to generate a large number of electron-hole pairs, holes and electrolyte are subjected to an oxidation reaction under the action of a built-in electric field formed by the solid-liquid heterostructure and migrate to the cathode, electrons are transferred to the cathode through an external circuit and subjected to a reduction reaction with the electrolyte, and a closed loop is formed to generate output current.

Description

technical field [0001] The invention relates to the field of battery energy, in particular to a radioactive three-dimensional nanostructure radiation electrochemical battery. Background technique [0002] With the rapid development of integrated circuit systems and micro-electromechanical systems, the volume of electronic devices is getting smaller and smaller, which promotes the miniaturization of energy supply devices, making it an urgent problem to be solved in the development of micro-sensing systems. Especially for autonomous wireless sensing microsystems deployed in remote and inaccessible places such as deep sea, deep space, polar regions, and deserts, there is a growing demand for independent, low-power, sustainable, and maintenance-free power supplies. At present, the traditional conventional power supply is subject to its own factors such as working principle and battery structure, and has certain defects in the application of extreme environments. For example, li...

Problems solved by technology

This makes on the one hand the specific surface area of ​​the radiation source used is small, and the energy conversion efficiency of the isotope cell is low. On the other hand, the radiation source has inevitable radiation damage to the semiconductor structure, which also leads to low energy conversion efficiency.
