Title: Electrochemistry and structural chemistry of LiNiO[sub 2] (R[bar 3]m) for 4 volt secondary lithium cells

Abstract

The synthesis and characterization of LiNiO[sub 2] for a 4 V secondary lithium cell was done. The LiNiO[sub 2] was prepared by ten different methods and characterized by X-ray diffraction and electrochemical methods. LiNiO[sub 2] prepared from LiNO[sub 3] and NiCO[sub 3] [or Ni(OH)[sub 2]] exhibited more than 150 mAh/g of rechargeable capacity in the voltage range between 2.5 and 4.2 V in 1M LiClO[sub 4] propylene carbonate solution. The reaction mechanism was also examined and explained in terms of topotactic reaction. Lithium nickelate (III) (R3m; a[equals]2.88 [angstrom], c[equals]14.18 [angstrom] in hexagonal setting) was oxidized to nickel dioxide (R3m; a[equals]2.81 [angstrom], c[equals]13.47 [angstrom]) via Li[sub 1[minus]x]NiO[sub 2] (0.25(2) [le]x[le]0.55(2)) having a monoclinic lattice (C2/m). The nickel dioxide could be reversibly reduced to lithium nickelate(III). Factors affecting the electrochemical reactivity of LiNiO[sub 2] are given and the possibility of using LiNiO[sub 2] for 4 V secondary lithium cells is described.
