Some research shows that

2、sub-micrometer pore dimensions are critical for preventing internal shorts between the anode and the cathode of the lithium-ion cell, particularly as the separators are as thin as 25 mm or less. The influence of PPTA pulp dosage to the maximum and average pore size of separator is shown in Figure 3.

3、 With the increase of PPTA pulp dosage, the maximum pore size and average pore size of the separator remain on a downward trend. When the PPTA pulp dosage reaches 40%, the pore size of the separator is decreased obviously. The pore size of the separator can be well controlled to less than 1 mm.该隔膜应孔

4、径分布均匀，以避免由于不均匀该隔膜应孔径分布均匀，以避免由于不均匀造成性能损失。造成性能损失。研究表明研究表明，亚微米孔隙尺寸，亚微米孔隙尺寸是针对预防性内部的阳极和锂离子电池的阴是针对预防性内部的阳极和锂离子电池的阴极之间的短路的关键，特别是隔膜是薄如极之间的短路的关键，特别是隔膜是薄如2525毫米或更小的。毫米或更小的。PPTAPPTA浆液剂量对隔膜最大和浆液剂量对隔膜最大和平均孔径平均孔径的影响示于图的影响示于图3 3。随着随着PPTAPPTA浆液剂量浆液剂量的增加的增加，最大孔径和平均孔径都，最大孔径和平均孔径都呈下降的趋呈下降的趋势势。当。当PPTAPPTA浆液剂量达浆液剂量达404

5、0时，隔膜的孔隙时，隔膜的孔隙尺寸明显减小，隔膜的平均孔隙尺寸可以很尺寸明显减小，隔膜的平均孔隙尺寸可以很好地控制到小于好地控制到小于1mm1mm。Figure 3. The influence of PPTA pulp dosage to the pore size of separator.图3 PPTA剂量对隔膜的孔径的影响 The pore size distribution of the separators with PPTA pulp dosage ranging from 20% to 100% is shown in Figure 4. It can be seen that

6、 the pore size distribution is not continuous. Parts of large pores appear near the maximum pore size, and another centralized zone of scatter is near the average pore size. The reason for the discontinuous distribution of the pore size might be that the maximum pore size depends on the coarsest fib

7、ers diameter and the defects of nonwoven, but the average pore size depends on the most common fiber diameter. In Figure 4a, when PPTA content is 20%, there are almost 95% pores in the range of 0.720 10.000 mm, but the maximum pore size of wet-laid nonwoven is 26.923 mm. This means the separator may

8、 have some defect such as pinholes and cannot meet the requirement of the separator. In Figure 4 f, the pore size distribution of the separator prepared with pure PPTA pulp is shown. There are about 3% of the pores near the maximum pore size of 0.895 mm, and almost 97% of the pores are at the range

9、of 0.118 mm0.500 mm, which indicates that the separators uniformity is improved obviously. PPTAPPTA浆液剂量浆液剂量范围从范围从20 20 到到100100的孔径的孔径分布示于图分布示于图4 4。该孔径分布是不连续的，孔径分布最多部位附近出现最大。该孔径分布是不连续的，孔径分布最多部位附近出现最大孔径。孔径的非连续分布孔径。孔径的非连续分布原因可能是原因可能是最大孔径取决于纤维的最大直径，但其平均孔径依赖于最常见的纤维直径。最大孔径取决于纤维的最大直径，但其平均孔径依赖于最常见的纤维直径。在在图图

10、4A4A中中，当，当PPTAPPTA含量为含量为2020 ，孔隙在，孔隙在0.7200.720m- 10.000- 10.000m的范围内的占的范围内的占9595，但此时湿法成网非织造布的最大，但此时湿法成网非织造布的最大孔径为孔径为26.92326.923m。这意味着这意味着隔膜可能有一些缺陷不能满足隔膜的要求：如针孔。隔膜可能有一些缺陷不能满足隔膜的要求：如针孔。如图如图4 F4 F中中，100%100%纯纯PPTAPPTA量时的孔量时的孔径分布情况：有径分布情况：有9797的小孔分布在的小孔分布在0.1180.118m- 0.500- 0.500m的范围内，只有的范围内，只有3%3%的小

11、孔分布在最大孔径为的小孔分布在最大孔径为0.8950.895m附近。附近。这表明这表明该分离器的均匀性该分离器的均匀性得到明显改善得到明显改善。Figure 4.

14、 dosage increases. This is because, initially, the binder fibers lead to an increase of the bonding strength of the PPTA fibers and when the PET fiber content reaches a certain point, the bonding fibers form a low tear strength membrane itself. When the PET dosage is 20%, the tear index of the separ

15、ator is 5.16 mNm2g-1, which is increased by 59% than that of the pure PPTA pulp. Based on the analysis of the pore size and the mechanical properties, the wet-laid nonwoven material whose PET content is 20% is chosen, as a preference,for the following properties study.从图从图7 7中得出中得出，撕裂指数随，撕裂指数随PETPET

16、纤维含量纤维含量增大而增加，到达增大而增加，到达一定剂量一定剂量后开始降低。后开始降低。这是因为这是因为：开始时开始时粘合纤维与粘合纤维与PPTAPPTA纤维接合，强度开始增加，但纤维接合，强度开始增加，但当当PETPET纤维的含量纤维的含量达到某一点时达到某一点时，粘合纤维的撕裂强度低隔膜本身的强度，所以撕裂强度开始下降。，粘合纤维的撕裂强度低隔膜本身的强度，所以撕裂强度开始下降。当当PETPET用量为用量为2020时，隔板的撕裂指数为时，隔板的撕裂指数为5.16mNm/g5.16mNm/g，与纯，与纯PPTAPPTA浆液相比，增大浆液相比，增大59%59%。基于前面基于前面对孔径和机械性能

17、等性能对孔径和机械性能等性能的分析的分析，可以得出湿法成网的非织造材料中，可以得出湿法成网的非织造材料中PETPET含量为含量为2020时性能较好又能满足作为电池隔膜的要求，因此对时性能较好又能满足作为电池隔膜的要求，因此对20%PET20%PET、80%PPTA80%PPTA混混合的非织造材料隔膜的性能进行研究。合的非织造材料隔膜的性能进行研究。Figure 7.

18、 10, the LOI of polyolefin membrane and nonwoven material decreases with the increase of temperature. The LOI of the nonwoven separator is higher than that of the polyolefin membrane at the same temperature because of the excellent flame retardancy property of PPTA fiber.在图在图1010中，聚烯烃膜和非织造隔膜的中，聚烯烃膜和
