Method of producing negative electrode for secondary battery
摘要:
A method of producing a negative electrode for a secondary battery, which includes: forming a negative electrode structure including a negative electrode current collector having two surfaces and a negative electrode active material layer formed on at least one surface of the negative electrode current collector; preparing a pre-lithiation cell including the negative electrode structure, a lithium metal counter electrode disposed to face the negative electrode active material layer of the negative electrode structure, and a separator interposed between the negative electrode structure and the lithium metal counter electrode; immersing the pre-lithiation cell in a pre-lithiation solution; and carrying out pre-lithiation by electrochemically charging the pre-lithiation cell while pressing the pre-lithiation cell at a pressure of 15 kPa to 3,200 kPa.
