HIPORE™ is Asahi Kasei's polyolefin film, used in a wide range of high-technology fields, such as lithium ion battery separators.
The membranes look like plastic films, but are actually filled with microscopic pores. HIPORE™ is high-performance microporous membrane with wide range of thickness and highly uniform pores.
|Made of polyolefin, does not emit harmful gases when incinerated.
|Available in a wide range of thicknesses with excellent uniformity of membrane thickness.
|Available with uniform submicron pores.
|High porosity, for outstanding liquid holding capacity.
|High puncture strength, for improved safety and reliability.
Batteries are indispensable for mobile electronics products. HIPORE™ is widely used as a separator in lithium ion rechargeable batteries and primary lithium batteries, having earned an outstanding reputation for high performance and safety. HIPORE™ separators are under development for a variety of other types of battery.
Demand is growing rapidly for double-layer capacitors as power back-ups to preserve data stored in the memory of mobile telephones, VCRs, and other electronic devices. HIPORE™ separators are widely used in such capacitors.
Our company is the proprietor of multiple domestic and international patent rights covering a particular separator for use in a lithium ion secondary battery(HiporeTM).
