Riset dan pengembangan baterai lithium mulai banyak dilakukan di Indonesia sejak awal dekade 2000-an. Diantara salah satu material yang dikembangkan adalah bahan aktif katoda LiFePO4,dengan harapan bahwa seluruh bahan baku pembuatan LiFePO4 diperoleh dari sumberdaya lokal. Sumber-sumber bahan baku LiFePO4 sendiri adalah LiOH atau LiOH.H2O atau Li2CO3 atau CH3COOLi sebagai sumber Li, Fe2O3 sebagai sumber Fe, dan H3PO4 sebagai sumber PO43-. Diantara berbagai sumber bahan baku tersebut, Fe2O3 dan H3PO4 dapat diperoleh dari dalam negeri, namun sumber lithium masih harus impor. Oleh sebab itu, produksi LiFePO4 kedepannya tidak dapat 100% menggunakan bahan baku lokal. Namun, terdapat satu cara yang dapat dilakukan agar menggunakan 100% bahan baku lokal, yaitu pengembangan FePO4. FePO4 ini nantinya berpotensi untuk diproduksi dan diekspor sebagai bahan baku pembuatan LiFePO4. Disamping itu, FePO4 juga memiliki nilai tambah lain sebagai bahan pelapis pencegah oksidasi pada permukaan logam. Oleh sebab itu, material ini cukup strategis untuk dikembangkan di Indonesia.

LiFePO 4 nanorods composed of nanoparticles were synthesized from precursor phase Fe 3 (PO 4) 2 (H 2 O) 8 (vivianite) via hydrothermal reaction. Nanorods consisting of nanoparticles were formed by using L-(+)ascorbic acid as reducing and capping agent. Near-theoretical specific capacity is achieved at 0.1 C rate with excellent retention capacity of up to 50 cycles. Morphology of as-synthesized samples favours fast intercalation/deintercalation process with easy mass and charge transfer.

“…In recent decades the exploration of A2O-M2O3-P2O5 (A=monovalent cation and M=multivalent metal ion) system was used to isolate a large number of phosphates. Several well-known varieties of structures are reported in literature like NaSicon type A3M2(PO4)3 (A=monovalent ion, M = Al, Cr, Ti, Zr, Ga, Fe ...) [10][11][12][13], olivine structure LiMPO4 (M=Fe, Al , Co.) [14,15]. The Na7M4(P2O7)4PO4 with (M = Fe, Al, Cr) compound family containing mono-and pyrophosphate groups was discovered by De la Rochère et al [19].…”

The title compound, heptasodium tetrachromium(III) tetrakis(diphosphate) orthophosphate, was synthesized by solid state reaction. Its structure is isotypic with that of Na7M4(P2O7)4PO4 (M = In, Al) compounds and is made up from a three-dimensional [(CrP2O7)4PO4]7- framework with channels running along [001]. The Na+ cations are located in the voids of the framework. This compound has been investigated by X-ray diffraction and infrared (IR) spectroscopy. The conductivity measurements of the compound were carried out from 515 to 795 Kelvin using the frequency response analyzer with 0.05V amplitude signal over the range of 13MHz-5Hz. The conductivity of the sample at 574K is 0.45 10-6 S.cm-1. The activation energy Ea=0.73eV shows that Na7Cr4(P2O7)4PO4 is a medium ionic conductors. The monovalent cations conduction pathways in the crystal bulks are simulated by means of the bond valence model (BVS).
