Flexible thin-film batteries are ideally suited for a variety of applications where small power sources are needed. They can be manufactured in a variety of shapes and sizes, as required by the customer. By using the available space within a device, the battery can provide the required power while occupying otherwise wasted space and adding negligible mass.
The thin-paper battery is suitable for applications requiring low-voltage power (1.5V to 3.0V), where traditional button cell batteries are problematic to use. Such thin-film or power-paper batteries will work exactly like traditional batteries, but will be nearly as thin as a piece of paper. A power-paper cell can generate 1.5V of electricity, which is approximately the same output as that of a watch or calculator battery. A power-paper cell will be 0.5mm thick, and several cells can be used in combination to provide more power.
Non-rechargeable thin-film batteries are normally printed and may be either zinc-manganese chemistry (such as a paper battery) or lithium polymer chemistry. Chargeable thin-film batteries are lithium-ion batteries and have solid lithium cores rather than liquid cores, so they are less vulnerable to overheating and catching fire. They lose virtually no power over time, and can be recharged thousands of times before they need to be replaced. The thin-film industry is developing miniaturized versions of this technology. A thin-film battery can be smaller than a postage stamp and twice its thickness, can be manufactured in various shapes, and can attach directly to a computer chip.
Power-paper batteries are printed directly onto thin substrates such as paper, so they are far more flexible than any other batteries due to their ultra-thin profile, low thermal mass, and ability to operate in harsh environments. Non-rechargeable thin-film batteries are uniquely suited as power sources for one-time password display-type smart cards, semi-battery-assisted passive (BAP) radio frequency identification (RFID) tags, semi-active tags with sensors (used in functional packaging), cosmetic and medical patches, consumer music greeting cards, toys and novelties.
Rechargeable thin-film batteries are suited for ultra-low power energy harvesting systems for wireless sensor networks, including ultra-small scale energy harvesting power systems (below 100 milli-amps) of wireless devices. The batteries are rechargeable, which means their size need be no larger than required to satisfy the energy requirements on a single cycle, thus reducing cost and weight; this characteristic in itself may give birth to new applications.
Thin-film batteries – seamlessly integrated into the objects they power – will mirror other integrated circuits on the miniaturization curve, as power itself becomes a component subject to Moore’s Law. Vertical and lateral build-outs in the industry will swell, flooding the marketplace with myriad useful new gadgets and peripherals. All these advancements will provide the breakthroughs needed to put power anywhere, in any form factor imaginable. Power will be lightweight, fully mobile, inexpensive and pervasive.
STUDY GOAL AND OBJECTIVES
Thin-film battery power systems differ from regular rechargeable micro-batteries used in notebooks, PDAs and mobile phones, which are available in prismatic, cylindrical and button forms. Commercially, low-profile micro-battery buttons have thicknesses ranging from 0.9mm to 2.1mm, compared to thicknesses below 0.6mm for flexible thin-film batteries.
Rechargeable thin-film cells can be stored for decades yet retain almost all their charge, according to developers, and they deliver powerful bursts of energy whenever needed. In many applications, they also can be actively used for decades, since they can be charged and discharged tens of thousands of times. To date, small-scale power supplies have been the missing link in the information revolution, a significant obstacle to the ubiquitous computing “aware environments” and smart machines that have been heralded as the next big wave of silicon intelligence.
Within the decade, however, all this will change. As the micro-device market grows, new innovations will redefine the personal uses of power. The individual will be free from household and workplace power grids, relying – when desired – on personal (and personalized) mobile power systems. Connectivity, communication and knowledge management will be forever changed.
Roll-to-roll production of thin-film printed batteries will be low cost and high volume. These batteries can be manufactured in any size, shape, voltage, or power capacity needed. Thin-film batteries are positioned to become the next generation of lithium batteries for portable electronic applications.
Therefore, this study focuses on thin-film batteries that can be used in powering one-time password display-type smart cards, semi-BAP RFID tags, semi-active tags with temperature sensors (used in functional packaging or smart packaging), interactive merchandising displays, cosmetic and medical patches, greeting cards, toys and novelty items, as well as energy storage in ultra-low power (ULP) energy harvesting power systems (below 100milli-amps) of wireless devices.

The thin-film battery (TFB) market is an attractive and still-growing multimillion dollar market characterized by very high production volumes of thin-film batteries that must be extremely reliable and low in cost. Thin-film lithium and lithium-ion batteries are ideally suited for a variety of applications where small power sources are needed. By using the available space within a device, the battery can provide the required power while occupying otherwise wasted space and adding negligible mass.
Three very distinct types of flexible TFB technologies exist – lower performance printed TFBs, single-use higher performance lithium polymer (LiPo) batteries, and solid-state rechargeable lithium phosphorous oxynitride (LiPON) batteries (which are the most expensive). Currently, non-rechargeable zinc batteries can be fully printed and used in roll-to-roll manufacturing processes.
The range of possible applications for these batteries derives from their important advantages over conventional battery technologies. They can be made in virtually any shape and size to meet the requirements of an application. The batteries are rechargeable, which means their size need be no larger than is required to satisfy the energy requirements on a single cycle, thus reducing cost and weight, which in itself may give birth to new applications.
Up until now, various power factors have impinged on the advancement and development of microdevices. Power density, cell weight, battery life and form factor all have proven significant and cumbersome when considered for microapplications. Batteries of the future will need to be miniaturized, untethered, and portable.
