Abstract
Description
本発明は、電解質及びその製造方法、特にコロイド電解質、及び該コロイド電解質を混練方式で製造する製造方法に関する。 TECHNICAL FIELD The present invention relates to an electrolyte and a method for producing the same, particularly to a colloidal electrolyte and a method for producing the colloidal electrolyte by kneading.
現在の電解質の形態には、固体、液体やコロイドなどがある。液体電解質はイオン伝導率が高く、通電の効果が良いが、流動性を有するため、長時間使用されたり外力に押されたりすると、液漏れが生じやすく、電子部品が作動できなくなる。さらに、液体電解質には強酸や強アルカリなどの溶媒が含まれており、これらの溶媒が漏れると安全上のリスクを招く。固体電解質は、液体電解質の代わりに高分子や無機金属酸化物を用いることで、液体電解質の液漏れの問題を解決できるが、固体電解質と電極との間にインタフェース抵抗が存在するため、固体電解質のイオン伝導率が高くなく、電子部品の性能が望ましくない。コロイド電解質は固体電解質と液体電解質の間のものであり、双方の優位性を持ち、将来の電解質材料の主流となる。しかし、現在一般的なコロイド電解質には、濃度分布が不均一であり、光透過性が悪く、伝導率が低いなどの問題があり、このため、従来のコロイド電解質を改良する必要がある。 Current electrolyte forms include solids, liquids and colloids. Liquid electrolytes have high ionic conductivity and good current-carrying effects, but because they have fluidity, they tend to leak when used for long periods of time or are pushed by external forces, making electronic components inoperable. Furthermore, liquid electrolytes contain solvents such as strong acids and strong alkalis, and leakage of these solvents poses a safety risk. Solid electrolytes can solve the liquid leakage problem of liquid electrolytes by using polymers or inorganic metal oxides instead of liquid electrolytes. The ionic conductivity of is not high, and the performance of electronic components is undesirable. Colloidal electrolytes are between solid electrolytes and liquid electrolytes, having the advantages of both, and becoming the mainstream of electrolyte materials in the future. However, current common colloidal electrolytes have problems such as non-uniform concentration distribution, poor light transmission, and low conductivity.
本発明の1つの目的は、高粘着性、高透光率及び高伝導率の特性を同時に備える電解質を提供することである。 One object of the present invention is to provide an electrolyte that simultaneously possesses the properties of high viscosity, high light transmittance and high conductivity.
本発明の別の目的は、完成品が保存されやすく、生産力を高めるという特徴がある電解質の製造方法を提供する。 Another object of the present invention is to provide a method for producing an electrolyte that is characterized by easy storage of the finished product and increased productivity.
本発明のさらなる目的は、エレクトロクロミック技術、ポリマーリチウム電池、スーパーキャパシタンス及びスーパーバッテリーなど、電気化学エネルギー貯蔵や省エネ技術の分野に有用であるコロイド電解質、及び該コロイド電解質を混練方式で製造する製造方法を提供することである。 A further object of the present invention is a colloidal electrolyte that is useful in the field of electrochemical energy storage and energy saving technology, such as electrochromic technology, polymer lithium batteries, supercapacitances and superbatteries, and a method for producing the colloidal electrolyte by kneading. is to provide
