Problems solved by technology

There are also many research results on the preparation of ion-selective membrane electrodes. However, although the performance parameters of existing ion-selective membrane electrodes are very good, such as organic sulfonate polymer membranes, etc., their cost is very high. It is not suitable for large-scale promotion; while some existing sensitive films are relatively moderate in cost, but their strength and stability are insufficient

Abstract

The invention relates to a preparation method of a battery system using an ionic selective film, which considers 2-3 gram of polyvinyl ether (PVE) powder and 3-4 gram of polyvinyl chloride (PVC) powder as a substrate, and enables the substrate to be heated to reach a fusion state, then obtains 38-41 gram of sodium nitrite, 7-9 gram of sodium nitrite salt and 51-55 gram of potassium nitrate salt to serve as an electroactive material to mix and heat to the fusion state, enables the two fusion solution to be mixed and cooled to 90-110 DEG C, rolling the mixture to form a film, cools the mixture to obtain a sensitive film, and finally assembles to be the battery system. The battery system prepared by the method has the advantages of being good in strength and stability and low in construction cost.

Description

technical field [0001] The invention relates to a method for preparing a battery system using an ion-selective membrane. Background technique [0002] Ion-selective electrodes are one of the fastest-growing analytical techniques in recent years, and a systematic potential analysis method has been formed. The analysis method has the characteristics of simple equipment, convenient operation, suitable for on-site measurement and continuous automatic analysis and measurement, etc. New and important tools for analytical work related to agriculture, agriculture, etc. [0003] Ion-selective electrodes are a class of electrochemical sensors that mainly include three parts: [0004] (1) Sensitive membrane: it is the most critical part of the ion selective electrode, which determines the properties of the electrode, and its function is to convert the specific ion activity in the solution into the membrane potential; [0005] (2) Internal reference electrode: its function is to lead...
