Garnet-like Al and Ga co-doped LAGLZO (Li_{7–3(x + y)}Al_xGa_yLa₃Zr₂O₁₂) (x, y = 0.00, 0.05, 0.20, 0.25) powders were prepared in a Couette-Taylor reactor via calcination. Increased Ga content (x = 0.00, y = 0.20) was shown to be associated with improved densification and smaller grains in the sintered pellet, showing the highest ionic conductivity of 1.13 × 10⁻³ S cm⁻¹ at RT. The composite solid electrolyte (CSE) sheet is composed of LAGLZO and polyethylene oxide (PEO) polymer with LiClO₄ showing an ionic conductivity of 4.52 × 10⁻⁴ S cm⁻¹ at 70 °C. However, in the LSV and symmetric cell test, the addition of Ga to the CSE sheet increased the reactivity and over-potential against lithium metal. All-solid lithium batteries (ASLBs) were fabricated using a composite cathode, CSE sheet, and Li-metal anode. The initial capacity of the ASLB slightly increased in proportion to the increasing Ga content, but the capacity retention and rate characteristics decreased as a function of charge/discharge cycles. Capacity reduction was solved by the cell design comprised of the bi-layer CSE sheets (LGLZO-based CSE/LALZO-based CSE), which suppressed the reactivity with lithium metal. Thus, by applying a LGLZO-based CSE sheet to the cathode and LALZO-based CSE sheet on lithium metal in ASLBs, the initial cell capacity with NCM 424 was improved to over 130 mAh g⁻¹ and a capacity retention of 93% was obtained after 50 cycles.

 在Couette中制备了石榴石状的Al和Ga共掺杂的LAGLZO（Li _{7-3（x + y）} Al _x Ga _y La ₃ Zr ₂ O ₁₂）（x，y = 0.00，0.05，0.20，0.25 ）粉末-通过煅烧的泰勒反应器。显示出增加的Ga含量（x  ＝ 0.00，y  ＝ 0.20）与改善的致密化和烧结的粒料中较小的晶粒有关，在RT下显示出最高的离子电导率1.13×10 ^-3  S cm ^-1。复合固体电解质（CSE）片材由LAGLZO和带有LiClO _4的聚环氧乙烷（PEO）聚合物组成离子电导率为4.52×10 ^-4  S cm ^-1在70°C下。但是，在LSV和对称电池测试中，向CSE薄板中添加Ga会增加对锂金属的反应性和超电势。全固态锂电池（ASLB）使用复合阴极，CSE薄板和锂金属阳极制造。ASLB的初始容量与Ga含量的增加成比例地略有增加，但是容量保持率和速率特性随充电/放电周期的变化而降低。通过由双层CSE片（基于LGLZO的CSE /基于LALZO的CSE）组成的电池设计解决了容量降低的问题，该电池设计抑制了与锂金属的反应性。因此，通过将基于LGLZO的CSE薄板应用于阴极和将基于LALZO的CSE薄板应用于ASLBs中锂金属，NCM 424的初始电池容量提高到130 mAh g ^-1以上 50次循环后，容量保持率达到93％。
