Problems solved by technology

[0013] However, this copolymer is generally brittle, and more than 50% of it remains without decomposing at around 300°C. Especially if it is used to make a solid electrolyte for an all-solid battery, the following problems arise: Residual carbides, self-discharge or internal short circuit, etc.
[0015] However, polyisobutyl methacrylate starts to decompose at a lower temperature than other (meth)acrylic homopolymers, but its decomposition end temperature is almost the same as that of other homopolymers, and its decomposition characteristics are in the middle Deterioration, degreasing takes a long time, and as a result, when used as a solid electrolyte, there is the following problem: it becomes the cause of deterioration of the electrolyte
In addition, there is a problem that the characteristics of the all-solid-state battery deteriorate due to the residue of the binder resin
