Preparation and characterization of space meshed LiFePO_4/C and Li_(1-x)FePO_4
Source abstract
Abstract
LiFePO4/C particles whose partial appearance was three dimensional network structure was prepared by hydrothermal method with that acidified Li2CO3 as the lithium resource.Its highest specific capacity was 143.4mAh/g and no capacity lost was found after 100charge-discharge cycles at 0.5C.Li1-xFePO4 were prepared by chemically delithiated method.Li1-xFePO4 were characterized by XRD and EIS.Results show that,with the increasing extraction of Li+ from LiFePO4,XRD analysis of Li1-xFePO4 support the LiFePO4/FePO4 model.Surface resistance of cathode and anode increases at first and then decreases.
