Highly interconnected Si nanowires for improved stability Li-ion battery anodes

Abstract:

Silicon exhibits the largest known capacity for Li insertion in anodes of Li-ion batteries. However, because of large volume expansion/phase changes upon alloying, Si becomes powder-like after a few charge-discharge cycles. Various approaches have been explored in the past to circumvent this problem, including the use of nanomaterials, particularly Si nanowires. However, even though nanowires resist cracking very well, anodes based on Si nanowires still see their original capacity fade away u...
