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]. WebReferences.
