All these new technologies imply increased energy consumption. Is there a more efficient alternative to Li-ion power batteries? Can it be environment friendly?

Angstrom Power, a company specialized in batteries, are now trying to provide some Hydrogen fuel cell for mobile phones, and it looks like MOTOSLVR L7 was chosen to be the first one.

According to Angstrom, this kind of resource would provide twice the juice a standard battery would do plus less time consuming for recharge.

The company plans to release the first around 2010, however people have expressed concern about the safety of such a cell in a handheld device.

Another manufacturer, Samsung Electro-Mechanics, announced during the 2007 Korea Electronics Show that it has developed a micro-fuel cell and hydrogen generator that runs on H2O. It even presented a working prototype of the new "Micro Fuel Cell" which works with the Korean version of the Samsung SGH-i600. According to Samsung, the micro-fuel cell can generate up to three watts of electricity which is enough to be used in mobile devices. The new fuel cell could power a handset for 10 hours talk time, twice as long as standard rechargeable batteries.

There has been wide speculation over the environmental effect of Li-ion mobile phone batteries, especially when it comes to their disposal. Although Li-Ion batteries are free of heavy metals (lithium has a low atomic number), lithium's high degree of chemical activity can create environmental problems. When exposed to water, which is present in most landfills, the metal can burn, causing underground fires that are difficult to extinguish.
