A novel Si/Sn composite with entangled ribbon structure as anode materials for lithium ion battery
A novel Si/Sn composite anode material with unique ribbon structure was synthesized by Mechanical Milling (MM) and the structural transformation was studied in the present work. The microstructure characterization shows that Si/Sn composite with idealized entangled ribbon structured can be obtained by milling the mixture of the starting materials, Si and Sn for 20 h. According to the calculated...
متن کاملPorous Si anode materials for lithium rechargeable batteries
Si anode materials for lithium rechargeable batteries have received much attention due to their high capacity. The Si itself can alloy with lithium up to Li4.4Si, corresponding to 4212 mAh/ g (4.4Li + Si 4 Li4.4Si). However, the large volume expansion of over 300% due to the formation of various LixSiy phases generates enormous mechanical stress within the ionic character material, which become...
متن کاملUltrasonic Characterization of Advanced Composite Materials
With increased use of composite materials in critical structural applications it is more important than ever to independently assure structural integrity. Complexity of the advanced composite materials including layered and bonded structures represents challenges in developing optimized ultrasonic tests. Traditional ultrasonic NDT methods are inappropriate and often misleading when applied to a...
