Abstract

Abstract New Li-ion conductors with several different structure types are reported. Li 4B 7O 12(Cl,Br) and LiM 2P 3O 12 (MZr, Hf) have framework structures. The others are based on structures with isolated polyhedra in a network of edge-linked Li polyhedra and include Li 2+xC 1−xB xO 3, Li 3−x B 1−xC xO 3, Li 4+xSi 1−xSi 1−xAl xO 4, Li 4−xSi 1−xP xO 4, Li 4−2xSi 1−xS xO 4 and Li 5−xAl 1−xSi xO 4. Li 0.8Zr 1.8 Ta 0.2P 3O 12 has the best room temperature conductivity, ∼5 × 10 −6 (Ωcm) −1. At 300°C, the conductivities of Li 3.75Si 0.75P 0.25O 4, Li 3.4Si 0.3O 4 and Li 2.25C 0.75B 0.25O 3 are 1 × 10 −2 (Ωcm) −1. These compositions resist attack by molten li at 200°C and some can be easily prepared as dense ceramics.
