摘要
分析了甲基丙烯酸(MMA)接枝到聚丙烯(PP)隔膜表面对金属锂界面稳定性的影响。未处理的PP隔膜,界面电阻随着放置时间的延长而增大,约45 d后达到稳定值;接枝MMA后,界面电阻在放置初期很快达到稳定值,约为320Ω·cm2,稳定一段时间后,增大到新的稳定值380Ω·cm2。分析了隔膜表面接枝MMA对天然石墨电极界面阻抗行为的影响。
The influence of methyl methacrylate（MMA） -grafting into polypropylene（PP） separator on the lithium interface stability was studied. For PP separator without treating,the interface resistance increased as the shelving duration increased, reached to a constant after about 45 d. For PP separator grafted with MMA ,the interfacial resistance quickly reached to a constant value of about 320 Ω.cm2, after a duration interval ,increased to the new stable value of 380 Ω-cm2. The influence of MMA-grafting on the impedance response of natural graphite electrode interface was analyzed.
