Negative electrode for rechargeable lithium battery, method for manufacturing the same, and rechargeable lithium battery including the same

A negative electrode for a rechargeable lithium battery, the negative electrode comprising:

• a negative electrode current collector;
• and
• a negative electrode active material layer on the negative electrode current collector,
• wherein the negative electrode active material layer has a short axis extending in a first direction,
• wherein the negative electrode active material layer comprises:
• first regions opposing each other in the first direction;
• and
• a second region between the first regions, and
• wherein a ratio of a mixture density of the second region to a mixture density of the first regions is greater than or equal to about 85% and less than about 100%.

A method for manufacturing a negative electrode, the method comprising:

• preparing a negative electrode current collector;
• forming a negative electrode active material layer on the negative electrode current collector, the negative electrode active material layer having a long axis extending in a first direction, the negative electrode active material layer comprising a first region and a second region arranged along the first direction;
• and
• selectively performing a surface treatment process on the first region excluding the second region to remove a binder in a surface portion of the first region,
• wherein a mixture density of the first region is less than a mixture density of the second region.
