Super high energy density of Li3V2(PO4)3 as cathode materials for lithium ion batteries

Lithium ion batteries have many advantages such as high energy density, no memory effect, long time cycleability and friendly environment. One type of cathode material that can be developed is Li3V2(PO4)3. In this study has been carried out the synthesis of Li3V2(PO4)3 with a hydrothermal temperatur...

Description
Summary:Lithium ion batteries have many advantages such as high energy density, no memory effect, long time cycleability and friendly environment. One type of cathode material that can be developed is Li3V2(PO4)3. In this study has been carried out the synthesis of Li3V2(PO4)3 with a hydrothermal temperature variation of 140, 160 and 180 °C and calcination temperature at 800 °C. SEM images show that the morphology of Li3V2(PO4)3 has irregular flakes with a size between 1-10 µm. CV results show redox reaction occurs in the range between 3 V to 4.8 V with the highest specific discharge capacity of 136 mAh/g for specimen with temperature hydrothermal and calcination are 180 °C and 800 °C. This result demonstrates that Li3V2(PO4)3 has a great potential as cathode material for lithium ion battery.
