In particular, we focused on the distribution of the ZrO2 on the particle surface to study the relation between electrochemical properties of the coated cathode and the distribution of the coating materials in the particle. Based on the results from the composition analysis and electrochemical tests, it was found that the coating layer consisted of nano-sized ZrO2 particles attached non-uniformly on the particle surface and the ZrO2 layer significantly improved the electrochemical properties of the cathode by suppressing the impedance growth at the interface between the electrodes and the electrolyte. 한국전기화학회 Improving the Capacity Retention of LiNi0.8Co0.2O2 by ZrO2 Coating Article 2 전기화학회지, v.9, no.1, pp.6 - 9 전기화학회지 9 1 6 9 kci ART001203888 LiNi0.8Co0.2O2 zirconium oxide coating lithium ion batteries1. IntroductionRecently LiNi0.8Co0.2O2 has been considered as a promising alternative for conventional LiCoO2 cathodes for rechargeable Li-batteries since the Ni substitution to LiCoO2 LiNi0.8Co0.2O2 zirconium oxide coating lithium ion batteries1.
