After 3G its 4G Mobiles

---

The mobile industry all over the world is going to be credited with the fourth generation mobile phone... but not quite in the near future. The rat race of launching this mobile phone is gaining speed.
Till date, the 3G mobile phones like BlackBerry Bold and Apple’s iPhone that used third-generation networks for faster Web browsing and e-mail were in demand but this time the companies are yearning to take a step forward. But due to the ongoing crisis, that has gripped the world, the techno savvy will have to wait some time before this technological evolution reaches into their hands.

ADVANCED BATTERY

---

Altair Nanotechnologies Inc. (Altairnano) of Reno, Nevada, has invented and developed a nano-structured negative electrode material called nano Lithium Titanium Oxide (nLTO) that replaces the graphite used in "standard" Li-ion batteries with safe nanomaterials.

Altairnano performed "hot box" exercises on its batteries at temperatures up to 240°C - more than 100°C above the temperature where graphite-based batteries can explode - with zero explosions or safety concerns. In addition, high-rate overcharge, puncture, crush, drop and other comparative tests were also performed alongside a wide range of graphite-based battery cells with no malfunctions, explosions or safety concerns exhibited by the nLTO cells. Put to the same tests, the graphite cells routinely smoked, caught fire and exploded.
