Title: Synthesis and characterization of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} (R{bar 3}m) for lithium-ion (shuttlecock) batteries

Abstract

The synthesis and characterization of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} were carried out in order to improve the electrochemical properties of LiNiO{sub 2} for lithium ion batteries. Single phase of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} (R{bar 3}m; a = 2.86 {angstrom} and c = 14.24 {angstrom} in hexagonal setting) was obtained by heating a reaction mixture of LiNO{sub 3}, NiCO{sub 3}, and Al(OH){sub 3} at 750 C under an oxygen stream for 20 h and examined in nonaqueous lithium cells. LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} was oxidized to {open_square}{sub 3/4}Li{sub 1/4}Ni{sub 3/4}O{sub 2} in the voltage range of 3.5--4.8 V. {open_square} denotes the vacant octahedral sites in a cubic-close packed oxygen array. X-ray diffraction examinations of Li{sub 1{minus}x}Al{sub 1/4}Ni{sub 3/4}O{sub 2} indicated that the reaction proceeded in a single phase over the entire range. The rechargeable capacity was observed to be about 150 mAh/g based on the sample weight. DSC measurements on fully charged LiNiO{sub 2} and LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} at 4.8 V were also done and the effects of substitution of aluminum for nickel in LiNiO{sub 2} upon the electrochemical properties were discussed in terms of capacity, failure, and safety coupled with overcharge.
