摘要

The optimal heat-setting temperature for PP/HDPE bilayer separator is 130 ℃. At this temperature

the bilayer achieves maximum puncture strength

lowest Gueley value and ionic conductivity of 9.7 N

369 s/100 ml and 2.35×10

−3

S/cm

respectively. Heat setting at 130 °C enables the achievement of a high-safety composite separator with excellent performance.

Abstract

Due to the mechanical stability of PP layer

the PP/HDPE double-layer microporous membrane could be prepared at a higher heat-setting temperature than that of PE monolayer membrane. In this work

the effects of heat-setting temperature on the pore structure and properties of PP/HDPE double-layer membrane were studied. With the increase of heat-setting temperature from 120 °C to 130 °C

the length of connecting bridge crystal and crystallinity in the PE layer increase due to the melting of thin lamellae and the stability of connecting bridge structure during heat-setting. The corresponding air permeability

porosity

wettability of liquid electrolyte and mechanical property of the heat-set microporous membrane increase

exhibiting better electrochemical performance. However

when the heat-setting temperature is further increased to 140 °C

higher than the melting point of PE resin

some pores are closed since the lamellae and connecting bridges melt and shrink during heat-setting

resulting in a decrease of air permeability and porosity. In contrast

there is negligible change in the PP layer within the above heat-setting temperature region. This study successfully builds the relationship between the stable pore structure and property of microporous membrane during heat-setting

which is helpful to guide the production of high-performance PP/PE/PP lithium batteries separator.
