The lattice parameters of the material were calculated by MDI.Jade.5.0 soft, the lattice constants of the simple are: a=10.310Å, b= 6.001Å, c= 4.687Å, that is very close to the standard LiFePO4 data.
The uniform distribution of the carbon and appropriate reduction of the particle size can significantly improved the diffusion rate and the conductivity of the LiFePO4/C [6].

These data show that there is a latent potential for the use of gypsum in Brazil [2].The plaster can be considered a binding energy-efficient, which is of interest to the sustainability of construction: in its manufacturing process, while the Portland cement requires temperatures of 1450oC, emitting CO2 in the atmosphere, gypsum can be obtained with less than 170 °C, emitting water vapor.
In the case of reinforced concrete structural elements subjected to bending, the reduction of adhesion is characterized by decreased rigidity of these elements [5].

Fig. 4b shows broadening diffraction peaks of the porous film, which implies a reduction in crystalline size.
The barrier height () and the ideality factor (n) can be determined from the y-intercept and the slope of the fitted curve, respectively, by using a linear curve fit to the forward characteristics of ln(I) against the V data.

In addition, it can be reconstructed from the experimental data, without the need to know [3] [4] used the theory of systems of differential equations embedded.
Test Reduction in the impact, pressure disturbance involving the HV system having the grid and with respect to a different point of view, the smaller the pressure conditions (i.e., the maximum switching power) on the storage device (i.e., calculated to assess the benefits of equal the interference is reduced in proportion to the economic cost of the storage device).
