Abstract To enhance the electrochemical performance of SiO, a simple electroless plating and ultrasonication method is used to prepare SiO/Cu/expanded graphite(EG) composite. Electrochemical results show that the electrode has a reversible specific capacity of 836 mAh/g and the capacity retention ratio is 90.2% in the 100th cycle at 200 mA/g current density (25 °C). Moreover, real time stress measurements quantitatively show that EG effectively suppresses stress development in the electrodes, which results in good cycling performance.
