Synthesis of Li1.3Al0.3Ti1.7(PO4)3 by sol–gel technique

“…Since then, a lot of attention has been paid to the studies of Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 for possible use in solid-state lithiumion batteries [3 -8]. Sol -gel method, which is one of the most used technique to synthesis various materials, has been introduced to prepare some solid lithium-ion electrolyte such as La 1/3 À x Li 3x TaO 3 [9 -11] and Li 3 Sc 2 À x Fe x (PO 4 ) 3 [12]. The technique has several advantages including good mixture of the reagents, relatively low crystallization temperature, and homogenous and small grain size of product.…”

Effects of Y³⁺-Doping on the Electrochemical Properties of LiV₃O₈ Cathode Material Prepared by a Solid-State Method

“…However, its practical application is limited by the rapid capacity fading and the unstable electrochemical properties, which are caused by the local damage of the crystal structure and the partial dissolution of the active material in the liquid electrolyte during the cycling [2]. In order to improve the electrochemical behavior of this material, some researchers have focused on the substitution of lithium with other cations such as Na + , K + , Mg 2+ , Ca 2+ , Cu + , Ag + [3][4][5][6][7] and that of vanadium with Mn, Mo, W [8,9], but they do not significantly improve the electrochemical performances of lithium trivanadates.…”
