Dreamweaver International, an advanced technology company whose products use a combination of nanofibres and microfibres to deliver best-in-class performance in lithium ion batteries and supercapacitors, has developed patented technology that will allow it to make the thinnest nonwoven separators in the world for lithium ion batteries and supercapacitors, as low as 10 – 12 microns.

The technology relies on lighter weights and much higher compression than other nonwoven battery separators. The innovation will allow the traditional benefits of nonwoven separators to be delivered at a thickness that is optimum for traditional lithium ion battery separators. The thickness is half the thickness of the dominant products in the supercapacitor industry, according to a press release.

Dreamweaver has prototypes for a 15 micron Titanium product developed for the supercapacitor industry, and a 20 micron Silver product developed for the lithium ion battery market. The products will be produced by Glatfelter, Dreamweaver's production partner.

Stephen Voller, CEO of ZapGoCharger Ltd., developer of ultra-fast charge graphene supercapacitors that can replace slow charging lithium-ion batteries, said, “This is a game changer for supercapacitors. The thickness reduction will complement our industry-leading energy density, making our supercaps even more competitive with batteries. Perhaps the most important part is that the cost per farad will decrease because of significantly reduced use of expensive electrolyte.”

Dr. Lin Cao, general secretary of China supercapacitor standard committee said, “Separator is an important component in supercapacitors. Technological advances for lighter and thinner separators with improved safety and stability are critical to drive developments and applications of the industry. They are also key elements to increase energy density and reduce the cost.” (GK)
