Our separator is a polyolefin microporous film which has a uniform microporous structure produced by our original dry manufacturing process. Our separator is the essential material for lithium-ion batteries (LIB) which has been used in the broad fields of LIB application for many years.
- Since pore shape of membrane is straight towards the direction of thickness, resistance to transmitting ions is low. So it is suitable for high charge and discharge of batteries.
- Heat shrinkage of transverse direction (TD) is greatly low because of one way (Machine Direction, MD) stretching process.
- Having a shutdown function, tri-layer structure, polyethylene is laminated between two polypropylene layers, is excellent in safety of batteries.
- Making the best use of straight microporous structure produced by our dry manufacturing process, we have mono (single) layer separator on our product portfolio.
- Without using solvent, our dry manufacturing process is good for the environment.
●Thickness range : 12-25 micron
CPORE® -Ceramic Coated Separator-
CPORE® is a high functional coated separator film which is produced by advanced dispersion technology and high speed and accuracy coating technology on the surface of separator film. CPORE® is produced by Ube Maxell Kyoto Co., Ltd..
- Excellent in resistance of heat.
- Excellent in resistance of short circuit.
- Having shutdown function, safety level is same as UPORE®.
●Thickness range(total thickness of base film and coating):13-25 micron
We can customize a specification of our product such as thickness, width, length etc. for your request. If you have an interest, please contact us.
- UPORE® is mainly used for rechargeable lithium-ion batteries (LIB). The product is folded between cathode and anode inside batteries. In case batteries become high temperature, pores shutdown, which prevent batteries from overheat. UPORE® is vital material for securing safety of batteries.
- UPORE® is suitable for lithium-ion batteries (LIB) which are required for high safety and high frequency of charge and discharge such as batteries electric vehicles (BEV), plug-in hybrid vehicles (PHEV), hybrid vehicles (HEV).
- Our product is fit for fast charging and discharging batteries which demand is growing for many applications lately such as automated guided vehicles (AGV), energy storage systems (ESS).
