BINDER FOR ANODE IN LITHIUM ION BATTERY, ANODE IN LITHIUM ION BATTERY COMPRISING THE SAME, LITHIUM ION BATTERY COMPRISING THE SAME, AND MANUFACTURING METHOD FOR THE SAME

摘要

In the present invention, provided is a binder for an anode in lithium ion batteries having a β-cyclodextrin polymer which is a hyperbranched net structure. Specifically, provided is the binder having the hyperbranched polymer net structure, which is originated from polymerization of a unique and large-sized structure of β-cyclodextrin (β-CD) and a three-dimensional structure of the unit β-cyclodextrin (β-CD). The binder facilitates interaction of Si-binder and self-healing ability and has an outstanding effect of improving mechanical stability on the film of electrodes, and can resolve chronic irregular cycle life of anode in Si.
