Design and developmental testing of electrical components for two-shaft Brayton cycle energy conversion system, discussing Na-Bi and Li-Te cells
Li2Te is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li1+ is bonded to four equivalent Te2- atoms to form a mixture of corner and edge-sharing LiTe4 tetrahedra. All Li–Te bond lengths are 2.82 Å. Te2- is bonded in a body-centered cubic geometry to eight equivalent Li1+ atoms.
Li3Te crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li is bonded in a 4-coordinate geometry to four equivalent Te atoms. There are two shorter (2.90 Å) and two longer (3.12 Å) Li–Te bond lengths. Te is bonded to twelve equivalent Li atoms to form a mixture of corner and face-sharing TeLi12 cuboctahedra.
LiTe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two LiTe3 sheets oriented in the (0, 0, 1) direction. Li is bonded in a hexagonal planar geometry to six equivalent Te atoms. All Li–Te bond lengths are 3.09 Å. Te is bonded in a distorted linear geometry to two equivalent Li atoms.
