Synthesis and Characterization of LiAl1 / 4Ni3 / 4 O 2 ( R 3m ) for Lithium‐Ion (Shuttlecock) Batteries

Abstract

The synthesis and characterization of were carried out in order to improve the electrochemical properties of for lithium ion batteries. Single phase of ( and in hexagonal setting) was obtained by heating a reaction mixture of , , and at 750°C under an oxygen stream for 20 h and examined in nonaqueous lithium cells. was oxidized to in the voltage range of 3.5–4.8 V. X‐ray diffraction examinations of indicated that the reaction
