    摘要: A polyurethane binder prepared by a polyurethane compound having double bonds and by crosslinking the polyurethane compounds. The polyurethane binder having double bonds can be dispersed in water with the dispersant including a reactive group such as a carboxyl group, and thus an organic solvent is not required to produce an electrode. The crosslinked polyurethane binder with a high crosslinking density provides an excellent elastic force and binding force, and thus the electrode and the lithium battery employing the polyurethane binder have improved recovery properties and charge/discharge properties.

    摘要: A composite anode active material includes a composite of a carbon-based anode active material, a metal-based anode active material and polymer particles. By increasing the conductivity of the composite anode active material, a lithium battery having a large capacity, high initial efficiency, high rate capability and improved cycle life performance can be obtained. An anode includes the composite anode active material and a lithium battery includes the anode.
