★四層復合隔膜(Al2O3/熱關斷層/PP/Al2O3)
Four-layer composite separator (Al2O3/ thermal shutdown layer/ PP/ Al2O3 )
關斷溫度:A型125℃ B型113℃
●產品特點Features
1.熱關斷溫度低:可提供兩款不同關斷溫度的產品琢歇,A型號關斷溫度為value="125" unitname="℃" w:st="on">125℃旭愧,B型號關斷溫度為value="113" unitname="℃" w:st="on">113℃拌倍。當鋰電池發(fā)生異常發(fā)熱姑子,達到關斷溫度時去扣,熱關斷層會立即切斷隔膜的離子通道孙咪,從而抑制電池溫度的進一步上升怪与,起到“保險絲”的作用夺刑。
2.熔破溫度高:氧化鋁涂層具有優(yōu)異的耐高溫性,在value="210" unitname="℃" w:st="on">210℃以上還能保持隔膜形態(tài)分别。
3.熱收縮行杂:在value="150" unitname="℃" w:st="on">150℃高溫下縱向熱收縮小于5%,橫向熱收縮保持為0茎杂。
4.高安全:雙層氧化鋁错览,安全系數更加高。
5.抗刺穿:氧化鋁涂層堅硬煌往,可阻止極片毛刺倾哺、粉塵及鋰晶枝刺穿隔膜。
6.耐氧化性:氧化鋁涂層可保護基材不被氧化刽脖。
7.良好浸潤性:氧化鋁涂層具有良好的吸液及保液能力羞海,提高充放電性能。
8.提升電池耐酸性:氧化鋁涂層可中和電解液中游離的氟化氫曲管。
9.低自放電率:氧化鋁涂層及熱關斷層增加微孔曲折度及硬度却邓,自放電大大低于普通隔膜。
10.循環(huán)壽命長:降低了循環(huán)過程中的機械微短路院水,有效提升循環(huán)壽命腊徙。
1.Low temperature of thermal shutdown: two types of different shutdown temperatures are available简十,i.e. the shutdown temperature of type A is value="125" unitname="℃" w:st="on">125℃, and the shutdown temperature of type B is value="113" unitname="℃" w:st="on">113 ℃. When the lithium battery occurs in abnormal heating, and reaches to the shutdown temperature, the thermal shutdown layer will immediately cut off the ion channel of the separator, so as to control the battery temperature to rise further, having the effect of "fuse".
2. High meltdown temperature: the aluminium coating enjoys excellent high temperature resistance, and can maintain separator form atvalue="210" unitname="℃" w:st="on">210℃ or above.
3.Shrinkage is low: MD shrinkage is less than 5% at the high temperature of value="150" unitname="℃" w:st="on">150℃, and TD shrinkage maintains 0.
4.High safe: the double-layer aluminium enjoys more secure performance.
5.Puncture-resisting: tough aluminium coating can prevent burrs of pole piece, dust and lithium dendrites from puncturing separator.
6.Oxidative resistance: Alumina coating can protect the base material from oxidization.
7. Good wettability: Alumina coating has good imbibition and liquid preserving capabilities, can enhancecharge and discharge performance.
8.Promote battery acid resistance: Alumina coating can neutralize dissociative hydrogen fluoride in electrolyte.
9.Low self-discharge rate: alumina coating and thermal shutdown layer increase microporous sinuosity and hardness that self-discharge of the separator is much lower than the ordinary separator.
10. Long cycle life: reduce mechanical micro short circuit in cyclic process and efficiently promote the cycle life.
