Layer-Structure lithium zinc borate, LiZnBO₃, is prepared by a solid state reaction of LiOH·H₂O, ZnO, and H₃BO₃ at 1000°C for 10 h. Highly preferred orientation and a layer-structure are observed in the powder XRD patterns and the SEM images, respectively. The Rietveld analysis indicates a monoclinic unit cell with space group C2/c, and the lattice parameters are refined as a = 8.827 Å, b = 5.078 Å, c = 6.171 Å, and β = 118.86°. LiZnBO₃ shows the capacity of 17 mAh/g between 1.3 V and 4.3 V (vs. Li/Li⁺) larger than ZnO.
