Cathode materials, traditionally used in industries, such as LiCoO2 , LiNiO2 , LiMn2O4 have pretty good electric performance, but expensive raw materials and toxic cobalt make them unsuitable for large-sized batteries production [1].
The cathode material LiFePO4 (LFP) is the best studied material among cathodes of the polyanion type (class of materials with tetrahedral structural unit (XO4)n-, and its derivatives (XmO3m+1)n- where (X=P, S, As, Mo, W), connected with the polygons MOx, where М is transition metals) [2-4].
However, as many other similar cathode materials of the polyanion type, Li2FeSiO4, still has insufficient conductivity (6*10-14Cm/cm) [8].

This paper design a new kind of grouting material, which is composed of coal fly ash and montmorillonite, these two grouting materials separately according to a certain proportion with pure cement material on the site grouting test and compare the compressive strength of the stones of the body and the size of the diffusion radius, and compare the grouting materials with pure cement materials.
Comparison analysis shows:The core compressive strength of pure cement materials and montmorillonite with cement mixing materials has little difference.
Comprehensive analysis and comparison of two kinds of materials as well as the advantages and disadvantages of pure cement, the compressive strength of pure cement injection and formation of montmorillonite and cement mixed materials can achieve the requirements of coal seam floor reinforcement.
