Laminates with Continuous Compositional Change (Functionally Gradient Materials) The concept of “Functionally Gradient Materials (FGM)” was proposed in Japan in 1984 and appeared in some journals from 1987 [5-8] to apply this type of materials into thermal protection for aerospace technology.

Introduction Olivine-type LiFePO4 is one of the most promsing cathode materials because of its high theoretical capacity (170mAhg−1), stable cycly ability, environmental benign, low-cost raw materials.
The cathode consisted of 78wt.% active materials, 15wt.% acetylene black and 7wt.% PVDF(Polyvinylidene Fluoride) on aluminum foil.
Fig. 3 shows the galvanostatic charge/discharge curves of the pristine and Mn–Cl co-doped LiFePO4/C materials.
The Li+ ion diffusion coefficient in olivine LiFePO4 is 7.15×10-12 by C-coating, while 5.48×10-11cm2 s−1 to the co-doped materials.

Its processing and material transfer the flexible big, but still low personnel flexibility.

The factors are simulated by ABAQUS software for the impact of seismic performance, which are difference of material strength grade, initial load and the order of prestressing and pretightening.
The factors are simulated by ABAQUS for the impact of seismic performance, which have different strength grade of materials, initial load, the order of prestressing and pretightening force.
The material strength of the new beams is higher than the initial beam, therefore, the damage of the new beam is lighter than it.
