| Product List |
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
【Packing】 25kgs/poly-drum ,500kgs/pallet.
