Lithium Secondary Battery and Manufacturing Method Thereof |
| abstract |
In the lithium secondary battery provided by the present invention, the positive electrode active material is composed of at least lithium and a lithium composite oxide containing nickel and / or cobalt as a constituent element, and the porosity of the positive electrode active material layer is 30% or more 40 It is% or less, and the porosity of a negative electrode active material layer is 30% or more and 45% or less. And the void volume ratio (Sa / Sb) of the void volume Sa per unit area in the said positive electrode active material layer, and the void volume Sb per unit area in the said negative electrode active material layer is 0.9 <= (Sa / Sb) <= 1.4 Satisfies. |
