Unlike conventional batteries, thin-film batteries can be deposited directly onto chips or chip packages in any size or shape. When deposited on thin plastics they are quite flexible. These batteries can be fabricated on a variety of substrates as well as onto chips, chip carriers and multichip module packages. Whereas conventional batteries, such as coin or button cells, contain organic liquid electrolytes and cannot survive high temperatures and, therefore, must be added to circuits as a separate component, often manually.

By using the available space on a ceramic package or a silicon die, these thin-film batteries can provide the power required while occupying otherwise wasted space. Yet, they add negligible mass. The company's batteries are intended for applications such as wireless sensors that operate in harsh environments, semiconductor diagnostic wafers, radio-frequency identification (RFID) tags, semiconductor non-volatile memory chips and advanced medical devices.

Oak Ridge Micro-Energy Inc. develops and produces thin-film lithium and lithium-ion batteries for a variety of applications where a small power source is needed. The company maintains R&D and manufacturing facilities in Oak Ridge, Tennessee and additional offices in Salt Lake City, Utah.
