2 - 2 - MANUFACTURING METHOD OF Si ALLOY-SHAPE MEMORY ALLOY COMPLEX FOR LITHIUM RECHARGEBLE ANODE ACTIVE MATERIAL AND Si ALLOY-SHAPE MEMORY ALLOY COMPLEX MADE BY THE SAME

摘要

The present invention relates to a method for producing a Si alloy-shape memory alloy composite for a lithium secondary battery anode active material, and a Si alloy-shape memory alloy composite for a lithium secondary battery anode active material produced thereby. The method for producing a Si alloy-shape memory alloy composite for a lithium secondary battery anode active material of the present invention and the Si alloy-shape memory alloy composite for a lithium secondary battery anode active material produced thereby form a composite of a shape memory alloy and a Si alloy , It is possible to manufacture a Si alloy-shape memory alloy composite for an anode active material for a lithium secondary battery excellent in capacity characteristics as well as life characteristics by minimizing the volume expansion and volume change of the Si alloy by charging and discharging.
