چکیده انگلیسی
A novel network composite cathode was prepared by mixing LiFePO4 particles with multiwalled carbon nanotubes for high rate capability. LiFePO4 particles were connected by multiwalled carbon nanotubes to form a three-dimensional network wiring. The web structure can improve electron transport and electrochemical activity effectively. The initial discharge capacity was improved to be 155 mA h/g at C/10 rate (0.05 mA/cm2) and 146 mA h/g at 1C rate. The comparative investigation on MWCNTs and acetylene black as a conducting additive in LiFePO4 proved that MWCNTs addition was an effective way to increase rate capability and cycle efficiency.
