Button cell with high-temperature-resistant system

Abstract

The invention provides a high-temperature-resistant system of a button cell, which belongs to the technical field of electrochemistry, and comprises a positive electrode shell, a negative electrode shell, a high-temperature-resistant sealing ring, a high-temperature-resistant diaphragm and a high-temperature-resistant electrolyte which are combined into the high-temperature-resistant system. The high-temperature-resistant system of the button cell is sequentially assembled by the positive electrode shell, the positive electrode, the high-temperature-resistant diaphragm, the negative electrode and the negative electrode shell, the high-temperature-resistant sealing ring is embedded in the edge of the negative electrode shell by a circle, and the high-temperature-resistant electrolyte is arranged between the positive electrode shell and the negative electrode shell and completely infiltrates the high-temperature-resistant diaphragm. The high-temperature-resistant system of the button cell has wide adaptability to button cells made of various materials. When a lithium / manganese dioxide-carbon fluoride system is used for testing under the condition of 150 DEG C, the voltage lag is relatively small, a discharge voltage platform is stable, and the capacity is not obviously different from that of normal-temperature discharge.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to a button battery with a high temperature resistant system. Background technique [0002] The Internet of Things (IoT) is a network of physical objects embedded with sensors, software and other technologies so that they can connect and exchange data with other devices and systems over the internet. IoT devices range from common household items to complex industrial appliances. Currently, there are more than 7 billion IoT devices connected to the Internet, and experts predict that this number will grow to 10 billion by 2020 and 22 billion by 2025. Over the past few years, IoT has become one of the very important technologies of the 21st century. Today, we can connect all kinds of everyday objects to the Internet through embedded devices, enabling seamless communication between people, processes and objects. One of the characteristics of the Internet of Things is compreh...
