Precise Control of Fluid on Nanostructured Surface Enables Breakthrough in Battery

(Nanowerk News) mPhase Technologies, Inc., the developer of Power On Command™ battery technologies, will be announcing this afternoon at the NanoBusiness Conference/NYC, an event sponsored by the NanoBusiness Alliance, that it has successfully bonded a glass reservoir capable of holding various electrolytes to the microfluidic structured layer of the mPhase Smart NanoBattery -- a key step in the packaging and assembly phases of this innovative new power source. The conference is being held at the Marriott Marquis Hotel in Manhattan.
The smart nanostructured membrane, which allows for the precise control of the liquid electrolyte, is the heart of the mPhase Smart NanoBattery. In its inactivate state, the electrolyte remains atop the battery's membrane surface; once triggered, the electrolyte comes in contact with the electrode material, producing voltage. The initial activation of the battery can be remotely controlled and pre-programmed.
The proprietary nanostructured membrane was created by mPhase and enabled by advances in microfluidics, nanotechnology and MEMS processing. In order to contain the electrolyte in its inactive state, mPhase had to create a hermetic bond between a glass reservoir holding the electrolyte and the nanostructured porous silicon membrane. "This was no easy task," said Ronald A. Durando, CEO of mPhase Technologies. "We had to bring together the expertise of our technical team, a MEMS foundry, and experts in glass machining and bonding, as the packaging and assembly of the elements of the battery are essential to the overall success of the project. The successful bonding of the glass reservoir to the microfluidic structured surface represents a key advance in the development path of commercializing the world's first Smart NanoBattery."
mPhase is on target to deliver a working battery this fall to the U.S. Army under a two-year STTR grant. The battery is designed to provide critical backup power to a computer's memory and can be diversified into many other applications.
