LITTLE FALLS, NJ - May 20, 2011 (Investorideas.com Newswire) - mPhase Technologies, Inc. (OTC.BB:XDSL) reported today that it has been granted a United States patent for the unique concept of a smart battery design that could contain different battery chemistries within the same battery configuration or battery pack. The concepts behind the patent could be used to create a new type of reserve battery that would work in a wide range of applications, such as electronic devices and sensors used in very high and low temperature environments, where the temperature conditions may change over time, or in other environments where optimal battery performance is not easily achieved based on a single non optimized battery chemistry.

The techniques described in the patent are based on the idea of creating individual cells within a battery system, where each cell could contain a custom combination of electrolyte and electrode materials. The patent describes how individual cells in a battery could be activated based on conditions such as the surrounding temperatures or other conditions such as power drain requirements, which can be used in determining which cells in the battery to activate. For example, if the outside temperature is sub freezing, cells containing a battery chemistry optimized for cold weather would be activated, or if the surrounding temperature became very hot, a different series of cells in the battery configuration could be activated.

The use of this patented technique may be incorporated into future battery designs by battery vendors and other applications, and is being evaluated in future designs of the mPhase Smart NanoBattery. mPhase Smart NanoBattery design uses electrowetting and microfluidic techniques to selectively activate and control the power generated by the cells in the reserve battery.

"This patent represents a major technical and business achievement in creating new approaches for designing batteries that can be used in applications requiring long shelf life, high availability and other programmable factors," said mPhase CEO Ron Durando. "This concept is a key component of not only something that can be implemented in our own products, but has applicability that could be incorporated by other vendors in the battery industry, as well as in other industries."
