Embodiment 1

[0111] 0.7 g of HASE and 0.3 g of polyacrylic acid were physically mixed and about 50 g of deionized water was added and mixed well. Afterwards, 1 g of conductive agent was introduced and mixed well. In addition, 98 g of an anode active material and about 50 g of deionized water were additionally added and thoroughly mixed to prepare an anode slurry composition.

[0112] The pH of the prepared anode slurry composition was about 6.9.

Embodiment 2 to Embodiment 5

[0114] An anode slurry composition was prepared by the same method as in Example 1 except that the content of each material was changed.

[0115] The compositions of the examples are respectively summarized in Table 1 below.
