Synthesis of LiFePO4 nanoplatelets as cathode materials for Li-ion batteries

Аннотация

Lithium iron phosphate with plateletlike morphology (length of 200 nm and thickness of 15–25 nm) was obtained using the solvothermal method. The resulting particles have the smallest dimension along the 1D channels, which are paths of Li⁺ ion migration. The discharge capacity of composite based on synthesized LiFePO₄ and carbon was equal to 160 mAh/g at a current density of 20 mA/g and 80 mAh/g at a current density of 800 mA/g.
