Dispersing agent for improving softness and toughness of cathode plate

Abstract

The invention discloses a dispersing agent for improving the softness and the toughness of a cathode plate. The preparation method comprises the following steps: mixing dihydroxy succinic acid with polyaziridine; reacting to obtain polyimide with hydroxyl; taking polyimide as a skeleton of a dispersing agent to be prepared, grafting solvated chains on the obtained polyimide, and carrying out mixedreaction on the grafted polymer and an oxide formed by removing one molecule of water from orthophosphate or one or two molecules of inorganic acid so as to prepare the finished dispersing agent. According to the dispersing agent for improving the softness and the toughness of the cathode plate, the dispersing agent can obviously improve the softness and the toughness of the cathode plate; dihydroxy succinic acid and polyaziridine are mixed and react to obtain polyimide with hydroxyl, the obtained polyimide is grafted with a solvation chain, and the grafted polymer reacts with acid anhydrideso that the cathode plate is more flexible, the conductivity of the cathode plate is improved, and the dispersing agent has a wide application prospect.

AI Technical Summary

Benefits of technology

This patented technology allows for better control over how well it works when making batteries by mixing two chemicals together: one called dihydroxysuccinylic acid (or DHS) and another substance that contains multiple amino acids or other molecules like aziridines). These chemistry create a special type of material called PolyImides which has many important qualities such as being able to be easily moldable into different shapes without losing its strength during use. Additionally, this new compound makes up part of the battery's electrolyte solution.

Problems solved by technology

This patented technical solution describes how different types of chemical agents called soluble polymers have been developed to achieve various benefits such as improved water-based paints' ability to maintain uniform distribution over surfaces without causing sedimentations due to excessive thickening caused by aggregates formed during production processes. Additionally, these solutions aim to enhance the quality of painted coatings while reducing defects such as streaks and uneven colors.
