2. LiFePO4 for cathode of Li-ion
High theoretical capacity- 170 mAh/g
Low cost of Fe if compare with Co (LiCoO2)
Drawbacks:
Low Li and electronic conductivity for both LiFePO4 and FePO4
Difficult to control valency 2+ for Fe during synthesis

3. Approach#1 Raw materials: Li2CO3 or LiOH, Fe(CH3COO)2, NH4H2PO4 xH2O
Temperature of synthesis 800 centigrade in Ar
Fe(CH3COO)2 too expensive
Low electrochemical capacity

4. Approach#2 Raw materials: NH4H2PO4, FeC2O4, Li2CO3
Temperature of synthesis: centigrade in N2
Low electrochemical capacity

5. Approach#3
Formation precursors of LiFePO4 by dissolving in water Li(1+), Fe(3+),PO4(3-) components without pressure. Example: LiOH, FePO4
Solid state reactions centigrade in N2/H2
Difficult to control Fe (2+) valency
Low electrochemical capacity

6. Approach#4 ( by Phostech Lithium)
Formation precursors of LiFePO4 by dissolving in water Li(1+), Fe(3+),PO4(3-) components without pressure.
Hydrothermal treatment of precursors
Electrochemical capacity 150 mAh/g
Low yield, secondary products necessary to recycle
Price for China customers 40 USD/kg

7. Hydrothermal approach by Mineral
Complete recycling of secondary products
Standard autoclaves for quartz synthesis are suitable for using after add special tools
Perfect crystal structure
Electrochemical capacity: 150 mAh/g
No patent issues- new technical solution
Not necessary purchase any gas (Ar,N2,H2 or others)

8. Efficiency of LFP-C powder production
Expected production cost in Korea (including, salaries, taxes) about 10 USD/kg Market price: 23 USD/kg for commercial grade (electrochemical capacity 120 mAh/g), 40 USD/kg for special grade (electrochemical capacity 150 mAh/g)

9. Market LFP cathode material
Size of the world market about tons/year with 50-80% annual growth
Main market: hybrid cars and motorcycles, solar
Phostech Lithium got investments 91 mln USD investments for production 2500 tons/year LFP
