Characterization of MgO-coated-LiCoO2 particles by analytical transmission electron microscopy

Autor: Hikari Sakaebe, Tomoki Akita, Noboru Taguchi, Kuniaki Tatsumi

Publikováno v: Journal of Power Sources. 328:161-166

The surfaces of LiCoO 2 particles were modified to improve the charge-discharge cycling properties of Li-ion batteries containing LiCoO 2 cathodes. The sol-gel technique was used to modify the surface of LiCoO 2 particles with magnesium oxide. Capaci
