Abstract
Provided is a lithium ion battery wherein the content of an iron element contained in a positive electrode active material (measured with an ICP emission spectrophotometer) is 10 ppm or more, and magnetic materials having a size of 0.70 times or greater than the thickness of a separator layer are substantially not included in order to provide a lithium ion battery which has small voltage drop during a charge state or under storage at high temperatures.
