Abstract

properties of the composites were determined by charge-discharge tests and cyclic voltammetry. The composite composed of Si∶Ag with an atomic ratio of 1∶1 (sample 1#) showed good cyclic stability and charge-discharge reversibility. The reversible capacity of the composite (sample 1#) was remained over 300 mAh·g^-1 after 50 cycles. Experimental results showed that controlling the potential range of charge-discharge processes could enhance the cyclic performance of alloy materials.
