Synthesis of Carbons Added UFePo_4 Powders by Two-fluid Nozzle Spray Pyrolysis and Measurement the Charge-Discharge Properties

摘要

LiFePO_4/C powders were synthesized by ultrasonic spray pyrolysis using carbon powder instead of organic substances as the carbon source. LiFePO_4 (LFP) powders containing different types of carbon powders were prepared and used as cathode active materials in lithium ion batteries. The charge-discharge properties of lithium ion batteries with LFP, LFP/AB, and LFP/CNT powders as the cathode material were worse than those of the battery with LFP/sucrose powder as the cathode active material.
