Benefits and Features
"Greener, Safer, Economic"
Benefits
Improved Safety
Dreamweaver's flexible technology platform has allowed us to choose materials that are inherantly more safe than traditional battery separators. By providing thermal stability at temperatures that are hundreds of degrees higher, Dreamweaver separators are an integral component of cells that have a much higher margin of safety.
|
Increased Power
Today's users of batteries need to be able to get the energy out, and in, quickly and efficiently. With smaller fibers and higher porosity, Dreamweaver separators get the separator out of the way, providing more efficient cells for energy storage, electric vehicles, e-bikes, wind energy and more.
|
Reduced Cost
In order for batteries to expand into the largest energy storage opportunities, the costs will have to come down, and not just a little bit. By using high volume non woven production techniques, Dreamweaver is able to bring a new paradigm of low costs to the energy storage separator industry.

Features
Increased Thermal Stability
Dreamweaver's flexible technology platform allows us to choose materials that have high thermal stability and flame retardant characteristics. Dreamweaver Gold uses Twaron, a para-aramid fiber that is stable at over 500 C, to create the ultimate separator in battery separator thermal stability, with only 2% shrinkage after 1 hour at 290 C.
|
Greater Efficiency
The smaller nanofibers used in Dreamweavers separators allow a separator with higher porosity, giving the ions more freedom to move quickly without impedance. This means that your electric tools and e-bikes have more power, and that charge times will be faster and more efficient in any application. Reduced electrical resistance is a key Dreamweaver characteristic
|
Reduced Pore Size
Dreamweaver takes normal textile fibers and then fibrillates them to a size far smaller than a micron. These fibers are then blended to achieve just the right properties, which include a very narrow distribution of pores, allowing the separator to keep the electrodes electrically isolated, while ions flow freely.
|
High Speed Production
Dreamweaver technology builds on decades of innovative development - development of high speed, high efficiency and high quality wet laid non woven production. This production process is routinely used in high quality technical filters and other applications. By drawing on this innovation and expertise, Dreamweaver products can be made on existing equipment at rates that far exceed normal battery separator production.

The Difference
Dreamweaver uses a completely new technology that brings with it the possibility to achieve benefits that could never before be realized with the current antiquated platforms. They now have all the tools available that were developed for nonwovens, and built those into their flexible technology platform. For this reason Dreamweaver is able to tailor their products to deliver what the market needs: safety, power, and cost reduction.
Today Dreamweaver products are bringing a new performance paradigm to lithium iron phosphate cells and supercapacitors. However, the advancements do not end there. Dreamweaver is following a technological roadmap that will provide separators at 10 microns. This separator will provide safety that cannot be delivered by other manufactures using current technology at any thickness. This will be done at a volume and economy that is suitable for automotive, electrical grid and green energy markets, in addition to more traditional applications like computers, cell phones and tablet computers.
For an example of such technology, see the video below; in a test that exceeds the boundaries of normal separator experiments, battery separators were saturated with lithium ion battery electrolyte and lit on fire. What you see on the left is that traditional separators shrink, deform, catch fire and burn, while the Dreamweaver separators remain dimensionally stable, providing safety and electrical isolation even during a battery thermal event.

Dreamweaver Silver (middle) and Dreamweaver gold (far right) remain stable even in the presence of burning electrolyte, while traditional separators shrink, deform, and then catch on fire and burn. Increased stability at higher temperatures is a key DWI separator safety feature.
