摘要：

The thin-film electrodes of LiNi0.8Co0.2O2 were deposited by pulsed laser ablation. The average thickness of these thin-films was measured by AFM to be approximately 0.62 mum. The electrochemical properties of LiNi0.8Co0.2O2 thin-films as working electrode in lithium cells were characterized by galvanostatic charge/discharge, cyclic voltammetry and ac impedance spectroscopy. The average capacity of these thin-film electrodes is about 60-62.5 muA/cm(2) mum. The Li+ diffusion coefficient in the LiNi0.8Co0.2O2 thin-film electrode was measured to be in the range of 3.19 x 10(-3) - 2.48 x 10(-10) m(2)/s. (C) 2001 Elsevier Science B.V. All rights reserved.
