Synthesis and electrochemical performance of macroporous LiNi0.5Co0.2Mn0.3O2 by a modified sol-gel method

Although the sample S2 delivered an initial capacity of 159.2 mAh/g tested at 300 mA/g, comparatively lower than that of S3, its capacity retention is markedly higher. Bacause the particle size and crystallinity strongly influence the cycling performance of the electrode materials.
