Analysis of the Separator Thickness and Porosity on the Performance of Lithium-Ion Batteries

Table 1

Comparison of the separators based on thickness, porosity, and specific capacity.

(a) Monolayer separator properties and discharge results comparison

Separator	Thickness	Porosity	Specific Capacity Uncalendered Electrode (mAh/g)	Specific Capacity Calendered Electrode (mAh/g)
2400 (PP) [Monolayer]	50 μm	41%	125.4	156.3
PP2075 (PP) [Monolayer]	40 μm	48%	119.1	133.5

(b) Trilayer Separator properties and discharge results comparison

Separator	Thickness	Porosity	Specific Capacity Uncalendered Electrode (mAh/g)	Specific Capacity Calendered Electrode (mAh/g)
H2013 (PP/PE/PP) [Trilayer]	40 μm	45%	141.9	156.1
H2512 (PP/PE/PP) [Trilayer]	50 μm	50%	140.2	144.3
