Abstract： |
| A kind of high electrolyte uptake PBI/ PEI (Short Name: PBEI) lithium ion battery separator was prepared by blending with polybenzimidazole(PBI) and polyetherimide (PEI) via vapor induced phase separation (VIPS) method. The internal microstructure of PBEI membrane presents a three-dimensional network structure. When the content rate of PBI reaches 40% (PBEI-4), the pore structure is the most loose and the porosity is the highest. Besides, due to the existence of ether bond, amide bond and imidazole polar groups, the electrolyte uptake of PBEI-4 separator is the highest, up to 391.84%. PBEI-4 membrane has good thermal stability and almost does not shrink at 160℃.The ionic conductivity of PBEI-4 membrane is 1.943 mS cm-1, much higher than that of PP (Polypropylene) membrane and PEI membrane. Under the same current density, the discharge capacity of PBEI-4 membrane is also higher than that of PP and PEI membrane. After 50 cycles of 5C current density, the capacity retention rate is 95.2%, which shows excellent cycle performance. |
