LONDON, Nov. 20, 2012 /PRNewswire/ -- Thin-film batteries hold the key to revolutionising miniature devices. Their flexibility, miniaturisation and high power attributes position thin-film batteries as the go-to power source for the next-generation of power- hungry gadgets. New analysis from Frost & Sullivan ( http://www.powersupplies.frost.com), Analysis of the Global Thin-film Battery Market, finds that the market earned revenues of $86.7 million in 2011 and estimates this to grow at an impressive rate to reach $1,986.5 million in 2018. "Thin-film batteries offer the flexibility to design a miniature gadget, with a reliable power source," noted Frost & Sullivan Energy and Power Supplies Industry Manager, Suba Arunkumar. "The inherent tendency to be only a few millimetres thick and the flexibility to be designed in different shapes make thin-film batteries suitable for specific niche applications." Thin-film batteries are benefiting from the trend of many consumer electronic devices converging into a single, miniature, multi-functional, high-powered gadget. The market is also being driven by the heightened need for small and light-weight security and surveillance devices. This ability to adapt to a wide range of applications is fuelling market acceptance. Radio-frequency identification (RFID) tags, smart cards, sensors, and spy gadgets could use these batteries for powering their devices. "Advancements in the manufacturing process of thin-film batteries will enhance their performance," advised Arunkumar. "This, in turn, will expand the base of end-user applications." Key challenges in this nascent market are the lack of standardisation and limited number of manufacturers. Those that are active have a regional, rather than global, profile. "Manufacturers need to compete in a common space, which could happen when all participants begin large-scale, high-volume commercial production," stated Arunkumar. "Mass commercial production will also be critical to bringing down the current high price of the technology."
