Abstract
The present invention provides a method for the fabrication of a LaZrGa(OH)x metal hydroxide precursor with a co-precipitation method in a continuous TFR. The present invention also provides a method for the fabrication of an ion-doped all-solid-state lithium-ion conductive material with lithium ionic conductivity, and mixing with the polymer-based material, then using a doctor-blade coating method to prepare free-standing double- or triple-layered organic-inorganic hybrid solid electrolyte membranes. Furthermore, the present invention provides an all-solid-state lithium battery using the aforementioned hybrid solid electrolyte membrane and the electrochemical performance of the all-solid-state lithium battery. The all-solid-state lithium battery may enhance the lithium ionic conductivity and lower the interfacial resistance between the hybrid solid electrolyte membrane and the electrodes, therefore the battery may have excellent performance, and prevent the lithium-dendrite formation effectively to enhance the battery safety.
