Abstract:Ultrafast high‐capacity lithium‐ion batteries are extremely desirable for portable electronic devices, where Si is the most promising alternative to the conventional graphite anode due to its very high theoretical capacity. However, the low electronic conductivity and poor Li‐diffusivity limit its rate capability. Moreover, high volume expansion/contraction upon Li‐intake/uptake causes severe pulverization of the electrode, leading to drastic capacity fading. Here, interface and morphology‐engineered amorphous… Show more
