Solid electrolyte, preparation method thereof and battery
The invention relates to a solid electrolyte, a preparation method thereof and a battery, and belongs to the technical field of solid electrolytes. The chemical general formula of the solid electrolyte is (LirXa) (BsYb) (StZc), wherein X is selected from any one of Na, K, Mg, Ca, Al and Fe; y is selected from any one of Si, Al, P, Ga and Ge; z is selected from any one of O, Se, F, Cl, Br and I. The solid electrolyte provided by the invention has four crystal forms, each crystal phase is good in crystallization, and the solid electrolyte can stably exist under normal pressure and has relatively good ionic conductivity. According to the preparation method, the distance between lithium ions is shortened by utilizing a high-pressure synthesis technology, so that the ionic conductivity of the electrolyte is improved, the reaction time is relatively short, and the prepared target product is single and free of byproducts.
本申请涉及一种固态电解质及其制备方法和电池，属于固态电解质技术领域。一种固态电解质，其化学通式为(LirXa)(BsYb)(StZc)；其中，X选自Na、K、Mg、Ca、Al和Fe中的任意一种；Y选自Si、Al、P、Ga和Ge中的任意一种；Z选自O、Se、F、Cl、Br和I中的任意一种。本申请提供的固态电解质具有四种晶型，各个晶相结晶良好，可以在常压下稳定存在,且具有较好的离子电导率。该制备方法利用高压合成技术以缩短锂离子之间的距离，从而提高电解质的离子电导率，且反应时间较短，制备出的目标产物单一，无副产物。
