A Battery Revolution
Dreamweaver has developed a new nonwoven battery separator made from a combination of nanofibers and microfibers that provides
- 300% Higher Power: The technology allows higher transmission of electricity in the battery, improving the power available in electric vehicles, power tools and other high power applications.
- Better Efficiency: The technology reduces the battery internal resistance, lowering energy dissipation and increasing efficiency.
- 23% Higher Energy Density: The technology allows more efficient use of the electrodes, increasing energy density.
- Thinner, lighter, smaller: Because of the above attributes, the technology allows for thinner, lighter and smaller batteries.

Our Technology
The job of a battery separator is to be a perfect barrier between the electrodes, while also acting as a perfect window to the electrolyte. Dreamweaver technology uses a combination of nanofibers and microfibers in a nonwoven structure that can give both.
- Perfect Window: The microfibers give an open structure, forming a tinkertoy network that is flexible yet strong and porous.
- Perfect Barrier: The nanofibers drape on the microfibers like spider webs on tinkertoys, giving a low pore size and narrow pore distribution that keeps the electrodes apart.
