Title:
二次電池用のリチウムイオンセル
Document Type and Number:
Japanese Patent JP6407265
Kind Code:
B2
Abstract:
The cell has a positive electrode (1) comprising an active material layer (2) in which active material particles in contact with non-aqueous electrolytes and particulate, porous additive are contained. Porous carbon particles are used as the additive, where porosity of the porous carbon particles lies in a region between 50% and 95%. The porous carbon particles comprise fluidic connected macropores, which are limited by carbon walls with a middle wall thickness within a range of 5 to 500 nm. The active material layer exhibits thickness of 75 nm or more.
