The decrementing comprises a gradient reduction from the middle layer to the inner core, and the gradient reduction refers to the fact that the mass-duty ratios on the circumference parts which have the same central distance from the inner core are the same, and when the distance from the center of the inner core is reduced, the mass-duty ratio is reduced step by step. The non-lithium silicate is generated in situ on the outer layer of the inner core, and has a non-water-soluble or non-alkaline or weakly alkaline compact structure, so that the dissolution of theinternal water-soluble lithium silicate can be effectively relieved; and the pH value of the ghost-eye composite negative electrode material can be lowered.

Oxygen-doping for non-carbon radical-component CVD films
Methods of forming silicon oxide layers are described. The methods include the steps of concurrently combining both a radical precursor and a radical-oxygen precursor with a carbon-free silicon-containing precursor. One of the radical precursor and the silicon-containing precursor contain nitrogen. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain very little nitrogen. The radical-oxygen precursor and the radical precursor may be produced in separate plasmas or the same plasma. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.

Method of resisting contaminant build up and oxidation of vehicle surfaces and other surfaces
Coating compositions and methods for applying reactive silanol coating compositions having electron deficient surfaces when cured wherein organic radical groups from the silanes are forced to the surface of the coating. The interpenetrating silicon-oxygen structure below the surface skews the electron cloud downward creating a net positively charged surface which is hydrophobic and oleophobic to repel contaminants by discouraging light hydrogen bonding. The surface is also extremely tight and thereby absent nutrients for microorganisms, discourages organic growth. These unique qualities provide cleanliness solutions for automotive and marine applications, including substrates subjected to elevated temperatures typically destructive to organic coatings (paints). Substrate examples are: brakes to repel brake dust on wheels; coating of engines and engine accessories, high-temperature exhausts / stacks / eductors, and engine compartments; automotive, architectural, industrial, and marine exterior substrates; and preservation and restoration of vehicles and boat interiors, seats, and instrument panels / dashboards and the like.
