The quality of diaphragm will influence the cycle life and self-discharge of battery to a great extent. The design of diaphragm hole, thickness and resistance have also become important indexes in judging battery quality. As to nickel-hydrogen battery, diaphragm with bad gas permeability will cause an increase of the internal pressure from oxygen produced by positive electrode due to overcharge which cannot be compounded. The increased pressure to certain value will be released from safety vent and cause the loss of electrolyte. Diaphragm with excellent gas permeability is helpful to the compounding of oxygen and can increase the battery capability of over-charge resistance.
【Application】
It is mainly used for the coating material of positive and negative pole diaphragm of lithium battery, which is beneficial to the stability of the battery.
It is suitable for Lithium ion battery separator,and the battery can be used for electronic car, electronic intelligent products and energy storage products.

【Product features】
Lithium ion batteries with alumina separator is fabricated for safety improvement. Alumina separator is coated on electrode by a scalable and cost-effective method.Lithium ion batteries with alumina separator perform better than conventional cells.
The presence of the alumina can significantly improve the physical and chemical properties of battery separators. The alumina coating layer may reduce or prevent dendrite puncture, lithium plating and separator shrinkage during over-heating, hence significantly increasing safety performance for a lithium ion battery
