The market advantage of a new technology or new product comes from the unique features which distinguish it from other technologies or products.  Compared to conventional batteries, the main feature of thin film batteries (TFBs) is that they are truly all solid state (no liquid or polymer).  All active layers of a TFB are made of inorganic materials.  Therefore, they are highly reliable, safe, and can be processed and operated in conditions where other batteries would fail.

Excellatron batteries have the following practical advantages:

Highly reliable and environmentally friendly.  No liquid or polymer in the active materials
Single cell operation at 4 V
High continuous discharge currents (up to 60C rate demonstrated at room temperature) and very high pulse discharge rate (up to 1,000C rate at elevated temperature)
Long cycle life (40,000 full depth-of-discharge (DOD) charge-discharge cycles demonstrated with specially designed lithium batteries)
Wide operating temperature range (-25ºC to 80ºC)
Wide storage temperature range (-55ºC to 300ºC)
Solder reflow process compatible (260ºC soldering followed by detergent and water wash) demonstrated with lithium ion batteries

TFBs are an ideal power source for applications that require a small current drain, high peak power output, and long durability.

Based on the unique advantages and properties of TFBs, the initial market for these batteries will be in devices that require a small current drain but have easy access for recharging. Examples of these devices include smart cards, active RFID tags, and printed circuit boards.  A solid state mini/micro battery is required in these applications because of the need for processibility and functionality under special conditions.Excellatron's battery technology is ideal to act as a microbattery or even a nanobattery for embedding onto a printed circuit board, flexicircuit or even into a microcircuit. These paper-thin batteries are the only power sources that can be made small enough to embed into MEMS devices and wireless micro sensors. These flexible batteries can also support electronic ink type displays. In addition, these rechargeable batteries also offer a battery-on-a-chip power solution for system-on-a-chip devices.

Other potential markets for TFBs include integrated circuits which require batteries that can withstand the solder reflow process, and medical applications that have stringent requirements for safety and durability.

With further advancement of our technology and development of the market, our next target market will be applications that require high temperature, high pulse power operations. Conventional lithium or lithium ion batteries, for example, cannot operate at 80ºC; but our battery can deliver pulse power (as high as 1,000C rate) at this temperature.
