Pics of mPhase's Manufactured Silicon Wafer for the Company's Smart NanoBattery

(Nanowerk News) mPhase Technologies, Inc. today released photographs of its six inch silicon based wafer that contains the key electrolyte separator membrane for the company’s Smart NanoBattery.

The slotted dark areas that can be seen on the wafer are the porous honeycomb membrane structures that allow the battery’s liquid electrolyte to be controlled in each of the twelve battery cells. Each of the individual slotted dark areas (porous honeycomb membrane) contain approximately 17,000 extremely miniature pores that the battery’s liquid electrolyte will eventually pass through. Each Smart NanoBattery is made up of twelve individual cells that are arranged in a 4 X 3 array. Each battery contains approximately 203,000 pores and each six inch wafer contains over 2 million pores.
A six inch silicon wafer contains the porous honeycomb membranes for ten Smart NanoBatteries. The membrane is uniquely designed to only allow liquid to pass through when the battery requires power. Until power is needed, the liquid electrolyte will simply rest on top of the porous surface without any leakage.
“These photographs represent the creation of a man made material that allows for the precise control of a fluid in the presence of a nanostructured surface,” said CEO Ron Durando. “We used advanced silicon processing and MEMS technology to create this unique and remarkable structure that can be used to improve reserve battery performance immensely.”
