Description
本發明係關於一種電解質及其製造方法,尤其是一種膠態電解質及透過混煉方式製造該膠態電解質之製造方法。The present invention relates to an electrolyte and a manufacturing method thereof, in particular to a colloidal electrolyte and a method for producing the colloidal electrolyte by mixing.
目前電解質的態樣可概分有固態、液態及膠態。液態電解質的離子傳導率高,且電流導通的效果佳,但是,由於液態電解質具有流動性,使電子元件在使用一段長時間或遭到外力擠壓時,容易產生漏液的情況,致使電子元件無法運作。此外,液態電解質內包含強酸或強鹼等溶劑,此等溶劑若是溢漏而出會有安全性的隱憂。固態電解質係使用高分子或無機金屬氧化物來取代液態電解質,可解決液態電解質之漏液問題,惟,固態電解質於電極之間存在有介面電阻,致使固態電解質之離子傳導率不高,導致電子元件的性能不理想。膠態電解質介於固態電解質與液態電解質之間,具有其雙方之優勢,將成為未來電解質材料之主流。然而,目前常用膠態電解質常有濃度分佈不均勻、透光性差及傳導率不佳等問題,因此,傳統膠態電解質有必要加以改良。At present, the state of electrolyte can be roughly divided into solid state, liquid state and colloidal state. Liquid electrolytes have high ionic conductivity and good current conduction effect. However, due to the fluidity of liquid electrolytes, electronic components are prone to leakage when they are used for a long time or are squeezed by external forces, resulting in electronic components not working. In addition, the liquid electrolyte contains solvents such as strong acid or strong base, and if these solvents leak out, there will be safety concerns. Solid electrolytes use polymers or inorganic metal oxides to replace liquid electrolytes, which can solve the problem of liquid electrolyte leakage. However, solid electrolytes have interface resistance between electrodes, resulting in low ionic conductivity of solid electrolytes, resulting in electrons The performance of the component is not ideal. Colloidal electrolytes are between solid electrolytes and liquid electrolytes, and have the advantages of both, and will become the mainstream of electrolyte materials in the future. However, the commonly used colloidal electrolytes often have problems such as uneven concentration distribution, poor light transmission, and poor conductivity. Therefore, it is necessary to improve the traditional colloidal electrolytes.
本發明之一目的在提供一種電解質,同時具有高黏著性、高透光率及高傳導率的特性。One object of the present invention is to provide an electrolyte with high adhesiveness, high light transmittance and high conductivity.
本發明之另一目的在提供一種電解質製造方法,具有成品易保存及提高生產量能的特性。Another object of the present invention is to provide a method for producing an electrolyte, which has the characteristics of easy storage of finished products and improved production capacity.
本發明之再一目的在提供一種膠態電解質及透過混煉方式製造該膠態電解質之製造方法,該電解質可應用於電化學儲能及節能技術之領域,包含電致變色技術、聚合物鋰電池、超級電容及超級電池等。Another object of the present invention is to provide a colloidal electrolyte and a method for producing the colloidal electrolyte by mixing. The electrolyte can be applied to the field of electrochemical energy storage and energy-saving technology, including electrochromic technology, polymer lithium battery battery, supercapacitor, and superbattery.
為達成上述及其他目的,本發明之電解質,包含:一高分子材料、一鋰鹽、一有機溶劑、一塑化劑、一離子溶液及一輔助材料,經混煉形成膠態,其中以重量百分比計,該高分子材料約為20~45%,該鋰鹽約為2~10%,該有機溶劑約為10~20%,該塑化劑約為10~20%、該離子溶液約為1~4%,該輔助材料約為1~4%。In order to achieve the above and other objects, the electrolyte of the present invention includes: a polymer material, a lithium salt, an organic solvent, a plasticizer, an ionic solution, and an auxiliary material, which are mixed to form a colloidal state, wherein In terms of percentage, the polymer material is about 20-45%, the lithium salt is about 2-10%, the organic solvent is about 10-20%, the plasticizer is about 10-20%, and the ionic solution is about 1~4%, the auxiliary material is about 1~4%.
