NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY CELL |
摘要 |
To provide a negative electrode for lithium-ion secondary battery, negative electrode which has good cyclability by suppressing the active material from coming off or falling down from the current collector. It has a current collector 1; and an active-material layer 6 in which a conductive additive 3; and an active material 2 being surface-treated with use of a surface treatment agent that is specified by a general formula: X-Si (CH 3 ) n - (OR) 3-n wherein: "n" is 0, 1 or 2; "OR" is a methoxy group, or an ethoxy group; and "X" is a methoxy group, an ethoxy group, or a vinyl group; are bound onto a surface of the current collector 1 via a binder 4 comprising a resin that has an alkoxy group-containing silane-modified part. |
