中文摘要	Partial oxygen in LiNi/sub 0.7/Co/sub 0.3/O/sub 2/ was replaced by chlorine to form LiNi /sub 0.7/Co/sub 0.3/O/sub 1.9/Cl/sub 0.1/. Phase structure of LiNi /sub 0.7/Co/sub 0.3/O/sub 1.9/Cl/sub 0.1/ was identified as a pure hexagonal lattice of alpha -NaFeO/sub 2/ type by X-ray diffraction. Discharge capacity of LiNi /sub 0.7/Co/sub 0.3/O/sub 1.9/Cl/sub 0.1/ was 202 mAh/g in initial cycle at 15 mA/g current density in 2.5-4.3 V potential window. The constant current charge/discharge experiments and cyclic voltammograms showed that chlorine addition was effective to improve reversible capacity and cycle stability of LiNi/sub 0.7/Co/sub 0.3/O/sub 2/.
