List of Tables
Table 1.1
The median voltage, specific capacity, crystallographic density
and volumetric energy density of some oxide materials that are
either commercially available or promising candidates for next
generation Li-ion batteries ...........................................

Table 3.1
Li x Ni 2−x O 2 properties obtained by fitting the X-ray diffraction
(XRD) patterns of the combinatorial samples. All samples were
prepared by heating for 3 h in a flow of approximately
30 mL/min of oxygen gas or in air in a box furnace. The
uncertainty values shown are the maximum for the entries in
each column. Size is shown for the samples made at 700
◦ C only

Table 3.2
Average Li 2 CO 3 crystallite size and microstrain. Values were
stable over the heating temperature range in which lithium
carbonate is present. The uncertainty is half the range in the
values ...................................................................

Table 6.1
The lattice parameters obtained for the single-phase corners of
the three-phase regions as well as the average values obtained in
the three-phase regions and the standard deviations (σ ). All
values are in Å. The uncertainty for the average lattice
parameters is calculated as σ/
