• PbGeO3/PPy nanocomposites are successfully fabricated for the first time.
• PbGeO3 nanowire and PbGeO3/PPy nanocomposites were characterized as anode materials in lithium ion batteries for the first time.
• PPy coating can improve the electrochemical performance of PbGeO3 by increasing the electronic conductivity and buffering the volume changes during cycling.
• The PbGeO3/PPy nanocomposites deliver a capacity of 662 mA h g−1 after 50 cycles.
PGO/PPy nanocomposites were prepared via a low temperature chemical coating method for the first time. Electrochemical measurements demonstrate that the PbGeO3 electrodes retain a capacity of 657 mA h g−1 after 100 cycles and possess excellent rate capability indicating that the PGO/PPy nanocomposites could be used as a candidate as high-capacity anode for lithium batteries.
