应用领域

LAGP is one of the top-choices for solid electrolyte in ASSLBs. LAGP powder is typically processed into thin films through pressing a pellet and sintering at temperatures between 800–900 °C. One advantage of LAGP compared to other solid electrolytes it that its thin films typically exhibit superior mechanical strength, crucial for resisting lithium dendrite growth and maintaining structural integrity within battery cells. Because LAGP is stable with most high-voltage cathode materials, LAGP is also commonly mixed with cathode material to form a composite cathode or "catholyte", which helps form continuous ionic conduction pathways through the interface between the electrodes and the solid electrolyte. Direct contact with lithium metal anodes, however, requires strategic interfacial engineering such as coatings or intermediary layers to promote stable anode/electrolyte interfaces. Furthermore, LAGP′s versatility extends to its role in polymer-ceramic composite electrolytes, where it synergizes with polymers such as PEO-LiTFSI to form a matrix that supports enhanced ionic conductance and structural flexibility.
