Solid State Lithium Thin Film Batteries:
ITN has used its expertise in thin film technology to create a unique battery that has numerous advantages over other rechargeable batteries and has been introduced into Commercial Markets (see below).

ITN continues to carry forward research and development into new methods and applications of thin-film battery technology.  One of the most exciting developments from this continuing research is the first thin-film battery technology around fibrous substrates, which we call PowerFiber. Developed under the auspices of DARPA, PowerFiber is expected to enable development of an entire new class of electronic textiles devices and novel composite power packs that simultaneously provide a variety of mechanical, optical, electronic, and electrochemical properties.

Commercial Markets:

• Implantable medical devices (hearing aids, pacemakers, etc.)
• Spacecraft multifunctional structures (where the power supply is also doing the work of structure)
• Flexible power packs that combine solar energy collection with energy storage all in one lightweight and versatile package
• Power for microelectronics such as smart identification cards, computer CMOS-RAM, etc

Design Features/Advantages

• Does not leak.
• Does not contain toxic materials like some batteries (NiCad).
• Can be recharged thousands of times and delivers an enormous lifetime capacity and lifetime energy per unit area and unit volume.
• Economical production: made with large-area, low-cost, vacuum processing (additional cost reductions will be made in the future as transition is made to roll-to roll configuration).
• Inherent thermal stability over extended temperature range enables direct integration into applications, such as electronics, as part of the fabrication process: demonstrated operating range between -45°C and 100°C.
• Versatile: Flat flexible form factor enables the battery to be used in many configurations, including prismatic and jelly roll (cylindrical) packaging, and bipolar stacking (prismatic) for increased capacity.
