詳細說明

層複合隔膜熱關斷層/PP/Al2O3

Three-layer composite separator (thermal shutdown layer/PP/ Al2O3)

關斷溫度:A125 B113

 

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,A型號關斷溫度為value="125" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">125B型號關斷溫度為value="113" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">113。當鋰電池發生異常發熱,達到關斷溫度時,熱關斷層會立即切斷隔膜的離子通道,從而抑製電池溫度的進一步上升,起到“保險絲”的作用。

2. 熔破溫度高:氧化鋁塗層具有優異的耐高溫性,在value="210" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">210還能保持隔膜形態。

3.熱收縮小:在value="150" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">150高溫下縱向熱收縮小於5%,橫向熱收縮保持為0

4.抗刺穿:氧化鋁塗層堅硬,可阻止極片毛刺、粉塵及鋰晶枝刺穿隔膜。

5.耐氧化性:氧化鋁塗層可保護基材不被氧化。

6.良好浸潤性:氧化鋁塗層具有良好的吸液及保液能力,提高充放電性能

7.提升電池耐酸性:氧化鋁塗層可中和電解液中遊離的氟化氫。
8
.低自放電率:氧化鋁塗層及熱關斷層增加微孔曲折度及硬度,自放電大大低於普通隔膜。
9
.循環壽命長:降低了循環過程中的機械微短路,有效提升循環壽命。

 

1.Low temperature of thermal shutdown: two types of different shutdown temperatures are available, i.e. the shutdown temperature of type A is value="125" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">125, and the shutdown temperature of type B is value="113" hasspace="True" negative="False" numbertype="1" tcsc="0" 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" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">210 or above. 

3Shrinkage is low: MD shrinkage is less than 5% at the high temperature of value="150" hasspace="False" negative="False" numbertype="1" tcsc="0" w:st="on">150℃, and TD shrinkage maintains 0.

4. Puncture-resisting: tough aluminium coating can prevent burrs of pole piece, dust and lithium dendrites from puncturing separator.

5. Oxidative resistance: Alumina coating can protect the base material from oxidization.

6. Good wettability: Alumina coating has good imbibition and liquid preserving capabilities, can enhancecharge and discharge performance.

7. Promote battery acid resistance: Alumina coating can neutralize dissociative hydrogen fluoride in electrolyte.

8.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.
9.
 Long cycle life: reduce mechanical micro short circuit in cyclic process and efficiently promote the cycle life.
