AC impedance of LiNi₀.₇Co₀.₂Al₀.₁O₂ and LiCo0₂ at room temperature / Nur Saidah Mohamed

New materials based on LiCo02 with some nickel and aluminium atoms substituted for other metals has become increasingly popular in cathode materials for Li-ion batteries. The purpose was to investigate AC impedance study of LiCo02 and LiNio.7Coo.2Alo.1O2 by electrochemical impedance spectroscopy (EI...
