Lithium ion battery solid electrolyte and preparation method thereof
The invention provides a lithium ion battery solid electrolyte and a preparation method thereof. The preparation method comprises the following steps of lanthanum oxide presintering, two times of ball milling, two times of drying, tabletting, sintering and sampling. Lithium carbonate, lanthanum oxide, zirconium dioxide, gallium oxide and tantalum pentoxide are mixed and stirred, a sintering curve is divided into four sections including a three-section heating curve and a one-section cooling curve, and the sintering temperature is adjusted by limiting the three-section heating and cooling rate; the doped and modified garnet type solid electrolyte belongs to a cubic phase, has better conductivity at room temperature, and has higher ionic conductivity.
本发明提供一种锂离子电池固体电解质及其制备方法，包括以下步骤：氧化镧预烧结、两次球磨、两次烘干、压片、烧结、取样；采用碳酸锂、氧化镧、二氧化锆、氧化镓、五氧化二钽混合搅拌，并且烧结曲线分四段，包括三段升温曲线与一段降温曲线，限定三段升温和降温速率调节烧结温度；掺杂改性后的石榴石型固体电解质属于立方相，在室温下具有更好的导电能力，其离子电导率更大。
