Abstract

Influence of ceramic separators with different base film on the performance of LiNi_0.8Co_0.15Al_0.05O₂ high power battery is researched, with conventional polyolefin separator as control experiment. The intrinsic performance of these three kinds of separators including micro-morphology, gurley number, and ion conductivity are investigated. For dry process base film ceramic separator, wet process base film ceramic separator and polyolefin separator, the air permeability are 165sec/100cc, 200sec/100cc and 520sec/100cc, respectively. The ion conductivity are 0.952 mS/cm², 0.703 mS/cm², and 0.622 mS/cm². Pouch cells of 2 A-h were prepared with three kinds of separators. Rate performance, cycle and capacity retention were tested. The results exhibit that the ceramic separator can improve voltage plateau compared with polyolefin separator, and the role of dry process base film ceramic separator in improving cell power performance is more evident than the wet process base film ceramic separator, especially when the discharge rate is increased to a margin level of the cell design.
