Webeither oxidized or reduced, resulting in a change in their ionic radii, which induces an overall expansion or contraction of the crystal lattice (occasionally with lattice distortion). These changes in the crystal lattice can cause particle fractures in the material leading to capacity fading [3,4] and/or increased resistance [5]. Web11 jan. 2024 · The authors attribute that to smaller ionic radius of the Co +2 (0.56 Å) and Ni +2 (0.55 Å) with respect to Zn +2 (0.60 Å), confirming that the Co +2 and Ni +2 ions are doped into the ZnO lattice. Our result seems then acceptable because the ionic radius of Fe +2 is (0.78 Å).
