SYNTHESIS MATERIAL
KATHODA LMP/C BERBASIS
BAHAN TEKNIS (M=Fe, Mn)
MATERIAL KATHODA
 Material Kathoda:
 LiMn(1-x)FexPO4 --- 0 < x < 0.15
 LiFe(1-x)MnxPO4 --- 0 < x < 0.2
 Technical Grade Materials:
 LiOH.2H2O  Germany, imported.
 Fe2O3  Puslit Metalurgi LIPI, local.
 MnO2  Puslit Metalurgi LIPI, local
 H3PO4  Brataco, local
 Gas Nitrogen  local
 Citric Acid  Cap Gajah, local
 Fructose  Rose Brand, local
TAHAP SINTESIS
 Mixing, Drying & Milling (#100 mesh) of starting
materials
 1st Heating Process
 300 - 400ºC
 5 – 10 hours
 N2 flow
 Milling (# 400 mesh)
 2nd Heating Process
 600 - 800ºC
 6 – 10 hours
 N2 flow
HASIL DAN ANALISIS
 LiMn(1-x)FexPO4 --- 0 < x < 0.15
 Fructose as carbon source
 Obtained Phase
LiMn(1-x)FexPO4 MnO
x = 0 91.9 % 8.1 %
x = 0.10 100 % -
x = 0.15 100 % -
ANALISIS PERFORMA
 LiMn(1-x)FexPO4 --- 0 < x < 0.15
 x = 0 (ongoing)
 x = 0.10
 x = 0.15
 Specific Capacity LiMn(1-x)FexPO4 (0 < x < 0.15)
masih rendah < 2 mAh/g
HASIL DAN ANALISIS
 LiFe(1-x)MnxPO4 --- 0 < x < 0.20
 Citric acid as carbon source
 Obtained Phase
LiFe(1-x)MnxPO4
x = 0 100 %
x = 0.10 100 %
x = 0.15 100 %
x = 0.20 100 %
ANALISIS PERFORMA
 LiFe(1-x)MnxPO4 (x = 0)
 LiFe(1-x)MnxPO4 (x = 0.10)
 LiFe(1-x)MnxPO4 (x = 0.15)
 LiFe(1-x)MnxPO4 (x = 0.20)
RINGKASAN: LiFe(1-x)MnxPO4
 Bahan teknis + methode synthesis menghasilkan katoda
dg fasa tunggal
 Specific Capacity 19 – 31 mAh/g, tertinggi x = 0
 Siklus sangat stabil dg x = 0.10 dan 0.15
 Coulombic Efficiency stabil 100% stlh siklus > 20
 C-rate tertinggi 10C, dapat dicoba utk > 10C
 Stlh variasi C-rate, tidak ada penurunan kapasitas yg
berarti. Kapasitas dg 0.5C sblm dan sesudah variasi C-
rate tetap
 Specific capacity perlu ditingkatkan agar mendekati nilai
yang lebih acceptable (70-90 mAh/g)
 Mampu utk aplikasi High C-rates spt EV
