LITTLE FALLS, N.J.--(BUSINESS WIRE)--April 7, 2005--mPhase Technologies Inc. (OTC:XDSL) has disclosed that its nanotechnology development roadmap includes a plan to produce a long-life nano battery boasting a four-fold increase in energy density as compared with potential Lithium Ion-based power cells.

In a presentation to the Stephens Inc. 2005 Nanotechnology Investors Conference in Pasadena, Calif., Steve Simon, executive vice president of research and development, this week reported that the company has entered into an agreement with Rutgers University to explore the technical issues required to increase the chemistry choices of its nano battery, now under development, to include a Lithium and water-based composition. This combination would significantly increase the power output capability of resulting devices.

In collaboration with Bell Labs, the R&D arm of Lucent Technologies (NYSE:LU), mPhase has already created a prototype battery based on a Bell Labs discovery that liquid droplets of electrolyte will stay in a dormant state atop microscopic structures called "nanograss" until stimulated to flow, thereby triggering a reaction producing electric current. Future batteries based on this technology have the potential to deliver far longer shelf life and better storage capacity than existing battery technology.
