mPhase Technologies Inc. reports the successful prototyping of its multi-cell Smart NanoBattery. This marks the completion of the technical work under the Phase 2 Small Business Technology Transfer Program (STTR) grant awarded by the U.S. Army.

The STTR funding enabled the mPhase technical team to develop functional prototypes and to conduct detailed analysis of the novel multi-cell reserve battery designs. The team was able to create a substantial IP portfolio and to achieve a Technical Readiness Level (TRL level) 4/5, which conventionally means that the original Smart Nanobattery design and technology used in its implementation progressed to the extent that they now meet the criteria for prototype testing in both laboratory and simulated deployment environments.

The completed Smart Nanobattery is based on a complex MEMS device consisting of layers of silicon and glass fabricated to the exact specifications of the mPhase team by its commercial foundry partner. The mPhase team finished the assembly by populating each battery with the electrode stacks of lithium and carbon monofluoride materials (Li/CFx), that delivered 3 volts per cell. Because of the unique design of the multi-cell battery, each cell in the battery has very long shelf life until it is activated via a technique called electrowetting, which gives the mPhase reserve battery one of its key attributes -- programmable triggering.

mPhase is currently working to secure additional funds to optimize the battery's design and increase the technical level of development towards commercial opportunities for defense and commercial applications.
