The latest publication by ITU-T’s Technology Watch looks into the major technological challenge of powering increasingly complex portable ICT devices.
Advances in processing power and new-generation communications links have increased mobility and driven the demand for mobile phones, laptops and other gadgets. Battery packs are a crucial ingredient of new technologies, not only in the ICT sector, but, also in other industries such as automobile. One report suggests that the $71 billion-a-year world-wide battery market – rechargeables accounting for two-thirds – could grow by 4.8 percent annually through 2012.
From a standardization perspective the report notes that to date, no common methodology or standardized procedure is available to provide exact and comparable information on battery runtime of ICT devices.
Batteries for portable ICT devices summarizes the trends and developments in battery technologies for mobile ICT devices. Today’s research on mobile power supplies mainly focuses on (a) incremental advances to current power solutions (e.g., Li-ion), (b) application of known alternative power supplies (e.g., photovoltaics, fuel cells) to mobile devices, and (c) the development of new battery concepts including nanotechnology. Advances in power supplies for mobile phones and other ICT devices are also important in bridging the digital divide and to address environmental issues.
Batteries for portable ICT devices is the second publication in a series of TechWatch Alerts (the first Alert addressed the topic Mobile Applications). Alerts are intended to provide a brief but concise overview of emerging technologies and trends in the field of ICTs.
