Smaller and thinner batteries with no leakage It is possible to obtain solid electrochemical devices such as electric double layer capacitors. However, it is extremely brittle and easy to break, so there is no way to solve this problem.
As stated in Publication No. 1, an attempt was made to create a solid electrolyte that was made flexible by combining an ion-conducting inorganic compound with a plastic resin, making it less likely to be damaged by mechanical shock, and using polyethylene oxide (PEO). A polymer solid electrolyte consisting of alkali metal salt and alkali metal salt has been proposed ("Fast J

Ishing Co, ). However, many of the inorganic compounds with low ion conductivity lack chemical stability including moisture resistance.In particular, conductors of alkali metal ions have poor chemical stability, and when combined with plastic resins, Although it has the disadvantage that it is difficult to handle because it is often deteriorated by unreacted groups such as active hydrogen in the plastic resin or by trace amounts of moisture and oxygen in the atmosphere during the manufacturing process.
-People Polymer solid electrolytes are lighter, more flexible, and more chemically stable than inorganic solid electrolytes, which is the problem that the invention aims to solve.However, compared to general plastic resins, they are less able to form a homogeneous film. The present invention has been achieved as a means to solve the problems in which it is often difficult to improve homogeneity and formability (film-forming ability), and the ionic conductivity decreases when trying to improve homogeneity and formability (film-forming ability). The solid electrolyte (friend) of the present invention
A polyether compound salt obtained by adding ethylene oxide (EO) and butylene oxide (BO) to a polyamine compound. An ion-exchangeable layered compound and an ionic substance represented by the formula MX (where M is the result of the action of an electric field. metal ions, protons, ammonium ions that move within the solid electrolyte composition, where X is an anion of a strong acid. The ionic compound MX forms a complex with a polyether compound and an ion-exchange layered compound, and is held at a high concentration between the layers or on the surface of the layered compound's crystals, forming an advantageous path for ion conduction. When manufacturing electrolytes
The polyether compound not only facilitates the miscibility of the solvent and the ion-exchange layered compound and promotes the formation of a uniform ion-conducting path, but also prevents the aggregation of the ion-conductive powder when it is added and mixed, thereby preventing the solvent and ions from agglomerating. This enables uniform mixing and dispersion with the exchangeable layered compound.In this way, high ionic conductivity and homogeneity are achieved. Furthermore, the ethylene oxide chain and butylene oxide chain of the polyether compound are entangled with the microporous structure of the ion-exchange layered compound to provide good moldability and sufficient mechanical strength.
