Colin McEwan,Maria-Isabel Silvahout this section, the method used to make samples in the Li-Mn-Ni-O system will be described. The only variation needed to make samples in the Li-Co-Mn-O system is to replace the nickel starting solution with a cobalt solution (both were nitrates in these studies). This method, developed by Carey a

Sarah Byrne,Anne Clarke,Robin Torrencethe main source of lithium loss was the decomposition of lithium carbonate that failed to react with the nickel oxide structure. The fact that the formation of LiNiO. was hindered significantly in air was attributed to the presence of constituents in air other than oxygen and nitrogen, the likeliest

Axial Scattering from Thin Conesd that the layered region is a single composition line corresponding to cobalt being constrained to the 3+ oxidation state only. This composition line, joining LiCoO. to Li.MnO., was a solid solution over its entire length when samples were quenched from either 800 or 900 °C. Upon slow cooling, the

All samples discussed here either contained one or two phases; and no evidence for nonequilibrium behaviour was seen. Two-phase fits in the coexistence regions were used to determine lattice parameters to allow the drawing of tie-lines. The lever rule

Though the thermodynamics of this are complex, a qualitative understanding can be achieved by considering the results of the Rietveld refinement. The R and M phases were collectively more ordered than the N and S phases (

The four-phase equilibrium was observed and transformations were found to be reversible, thereby confirming that two three-phase regions exist and transform during slow cooling. The primary importance of this work is a better understan

Materials made with 5 . excess lithium (at point B. in Fig. .) were found to stay single phase even when the regular cooling rate of 5–10 °C/min was used. These single-phase layered materi

Some approximations were made to join the two faces since the Li-Co-Mn-O face was synthesized in air while the nickel containing samples were made in oxygen. Nonetheless, the two faces join quite well. The pyramid strongly suggests that both single-phase regions of importance for
