A straightforward and scalable solid-state synthesis at 975° C. used to generate cathode materials in the system Li_(3+x)3Ni_(1-x-y)Co_yMn_2x/3O₂ {a combination of LiNiO₂, Li₂MnO₃, and LiCoO₂ as (1-x-y)LiNiO₂.xLi₂MnO₃.yLiCoO₂} is described. Coatings for improving the characteristics of the cathode material are also described. A ternary composition diagram was used to select sample points, and compositions for testing were initially chosen in an arrangement conducive to mathematical modeling. X-ray diffraction (XRD) characterization showed the formation of an α-NaFeO₂ structure, except in the region of compositions close to LiNiO₂. Electrochemical testing revealed a wide range of electrochemical capacities with the highest capacities found in a region of high Li₂MnO₃ content. The highest capacity composition identified was Li_1.222Mn_0.444Ni_0.167Co_0.167O₂ with a maximum initial discharge capacity of in the voltage range 4.6-2.0 V. Differential scanning calorimetry (DSC) testing on this material was promising as it showed an exothermic reaction of 0.2 W/g at 200° C. when tested up to 400° C. Cost for laboratory quantities of material yielded $1.49/Ah, which is significantly lower than the cost of LiCoO₂ due to the low cobalt content, and the straightforward synthesis. Li_1.222Mn_0.444Ni_0.167Co_0.167O₂ is thought to be near optimum composition for the specified synthesis conditions, and shows excellent capacity and safety characteristics while leaving room for optimization in composition, synthesis conditions, and surface treatment.

A method for controlling the synthesis gas composition obtained from a steam methane reformer (SMR) that obtains its feedstock as product gas directly from a steam hydro-gasification reactor SHR). The method allows control of the H₂/CO syngas ratio by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR. The steam and methane rich product gas of the SHR is generated by means of hydro-gasification of a slurry of carbonaceous material and water. The mass percentages of the product stream at each stage of the process are calculated using a modeling program, such as the ASPEN PLUS™ equilibrium process. By varying the parameters of solid to water ratio and hydrogen to carbon ratio, a sensitivity analysis can be performed that enables one determine the optimum composition of the slurry feedstock to the SHR to obtain a desired syngas ratio output of the SMR. Thus one can adjust the hydrogen feed and the water content of feedstock into the SHR that supplies the SMR to determine the syngas ratio output of the SMR.

In the step of forming a piezoelectric layer of the method for manufacturing a piezoelectric actuator, the piezoelectric layer is formed by using material particles M having a composition which differs from the optimum composition by the diffusion amount of Ti. The piezoelectric layer has a two-layer structure including a first piezoelectric layer formed on a vibration plate and a second piezoelectric layer laminated on the first piezoelectric layer. Only the first piezoelectric layer has a composition different from the optimum composition, and the second piezoelectric layer laminated thereupon has the optimum composition. When the piezoelectric layer of such a two-layer structure is subjected to the annealing treatment, the composition of the first piezoelectric layer is corrected and becomes the optimum composition by the diffusion of a diffusion element. On the other hand, because the diffusion does not advance to the second piezoelectric layer which is on the farther side from the vibration plate, the optimum composition of the second piezoelectric layer is maintained. As a result, good piezoelectric characteristic can be obtained.
