Negative electrode comprising mesh-type current collector, lithium secondary battery comprising the same, and manufacturing method thereof

A negative electrode for a lithium secondary battery comprising:

• a mesh-type anode current collector formed with a wire rod portion and an opening;
• a lithium thin film formed with an inserted portion inserted to the opening of the negative electrode current collector and a non-inserted portion that is not inserted;
• and
• a protection structure formed on a surface opposite to the lithium thin film that the negative electrode current collector faces,
• wherein the protection structure is formed with an organic polymer portion and an inorganic material portion, and the organic polymer portion is formed on a surface opposite to the lithium thin film that the wire rod portion adjoins and the inorganic material portion is formed on a surface opposite to the lithium thin film corresponding to the opening.

A method for manufacturing a negative electrode for a lithium secondary battery comprising:

• i) preparing a mesh-type anode current collector;
• ii) placing lithium thin film on the negative electrode current collector;
• and
• iii) rolling the lithium thin film and the negative electrode current collector to insert the lithium thin film to an opening of the negative electrode current collector.
