LITHIUM SECONDARY BATTERY AND MANUFACTURING METHOD THEREFOR |
摘要 |
The lithium secondary battery provided by the present invention includes a negative electrode having a negative electrode collector and a negative electrode layer including a negative electrode active material and formed on the surface of the negative electrode collector, and is characterized in that the negative electrode layer comprises a negative electrode active material layer composed primarily of a negative electrode active material, and an insulating layer composed primarily of an insulating filler and formed on the negative electrode active material layer, and the ratio (Sb/Sa) of a pore specific surface area of the insulating layer (Sb: m 2 /g) to a pore specific surface area of the negative electrode active material layer (Sa: m 2 /g), as measured by a mercury porosimeter, satisfies the relationship 1.2 ‰¤ (Sb/Sa) ‰¤ 2.5. |
