LLZGO (Li6.4La3Zr2Ga0.2O12) Powder as Solid-State Electrolyte for Lithium-Ion Battery, 25-100 g/bottle, CLIBSSELLZGO

Li6.4La3Zr2Ga0.2O12 (LLZGO) is a gallium-doped cubic garnet-type solid-state electrolyte (SSE). Gallium substitution Ga^{3+} on Li+ sites) stabilizes the high-conductivity cubic garnet phase at ambient temperatures while creating lithium-site vacancies that unlock high bulk ionic conductivity (Li > 10^{-3} S/cm at 25°C). It is widely deployed as a ceramic powder for fabricating dense sintered ceramic separators, as an active ion-conducting inorganic filler in composite polymer electrolytes (CPEs), and as a protective coating on high-voltage cathode active materials.

Un-doped Li7La3Zr2O12 (LLZO) stabilizes in a thermodynamically favored tetragonal phase at room temperature, which has ordered lithium sublattices and poor ionic conductivity (~ 10^{-6} S/cm). (1) Site Occupancy: Ga^{3+} preferentially substitutes at the tetrahedrally coordinated 24d =Li+ positions. (2) Sintering Aid Behavior: Beyond phase stabilization, gallium acts as an internal sintering aid. During high-temperature sintering (1050–1150°C), gallium-rich liquid transient phases lower the activation barrier for densification, allowing relative pellet densities >95–98% without excessive lithium volatilization compared to un-doped or standard Al-doped LLZO.
