A method of conventional chemical reaction to prepare delithiated cathode materials of Li-ion battery has been introduced.
A series of tests were conducted to verify the composition, crystal structure and electrochemical property of the delithiated cathode materials were all desirable.
Delithiated cathode materials with various lithium contents are needed in order to analysis the microstructure and properties.

The materials were characterized by XRD, BET, OSC and so on.
Phase structure in the materials is stable in the aging process.The addition of Mn in the oxygen-storage materials contributes to raise oxygen-storage performance of the materials.
The materials has the better oxygen-storage performance and heat stability when Mn content in the materials is 0.03.
The rare earth oxygen-storage materials as a critical materials of a vehicle exhaust purification three way catalyst have successfully been used[1].
(3) The addition of Mn content in the materials contributes to raise oxygen-storage performance of the materials.

Experiment Materials and Procedures Materials and Properties.
As a result, the steel surface materials were worn down.
Therefore, the wear mode of the steel surface materials may be changed.
The effect of water on the tribological properties of materials is complicated.
For example, in some cases, the existence of water may act as lubrication and reduce the friction coefficients and wear rates of materials, but it can also produce corrosion and oxygenation, and then aggravates the wear of materials [12].

For the same photon energy, this device has a lower value of α compared to Ge (α = 1.45 × 104 cm-1) and InGaAs (α = 2.18 × 104 cm-1).[19], [20] Overall, the α value above the energy bandgap is around 104 cm-1 which is within the estimated range for III-V semiconductor materials.
Other work on Bi-based material systems have reported similar behaviour due to disorder of the material and the tail can be extended about <100 meV below the bandgap.[13], [22]–[24].

Building materials accounted for 60% of the project cost in general building, while the cost of the decoration materials accounted for about 50% of the total cost of building materials, especially in the luxury building decoration, material costs accounted for about 70%.
Two aspects should be considered to select materials.
The interior decorative materials refer to the wall decoration, materials of furniture, and paint, floor tile, lighting, etc.
