Effect of Synthesis Time and Component Excess on LAGP Phase Composition

Solid-state lithium-ion batteries with NASICON-type electrolyte are a promising direction of the current source's development. One of the main problems of lithium-conducting materials with NASICON-type structure, LAGP in particular, is their relatively low electrical conductivity since the grain boundary and low-conductivity phases decreases the average conductivity of the material. The change of chemical composition during synthesis due to volatilization of the most mobile components directly affects the properties of the material and its crystallization. However, the method to influence the components ratio in LAGP has not yet been provided. Thus, the study of the synthesis time and the attribution of DTA exothermic peaks to specific phases are urgent scientific questions.
