A bio-mineralized composition for use in an electrochemical cell is described. The bio-mineralized composition may comprise a material represented by general formula y[Li1±xMaOc].(1-y)[Mb(PO4)3±d(Ap)1±e].Cz or y[Ma].(1-y)[Mb(PO4)3±d(Ap)1±e].Cz or y[Li1±xMaOc].w[Li2±xMaOc].(1-y-w)[Mb(PO4)3±d(Ap)1±e].Cz or y[MaOv].(1-y)[Mb(PO4)3±d(Ap)1±e].Cz where M represents at least one element; Ap represents group of mixtures; C represents Carbon or its allotropes; P represents element phosphorous; Si represents silicon; Li represents lithium; B represents boron; O represents oxygen and x, y, z, w, a, b, c, d and e represent a number.
