If you're finding that your notebook battery life falls a bit short of your expectations, then Sony has good news as the company has managed to improve the capacity of its Nexelion hybrid Li-Ion battery cells. The original Nexelion battery cells were introduced back in 2005 and back then offered a good bump in battery capacity and although it's taken six years, we're now getting another bump.

If you're finding that your notebook battery life falls a bit short of your expectations, then Sony has good news as the company has managed to improve the capacity of its Nexelion hybrid Li-Ion battery cells. The original Nexelion battery cells were introduced back in 2005 and back then offered a good bump in battery capacity and although it's taken six years, we're now getting another bump.

The current generation of Nexcelion cells are rated at 2.2Ah per cell, but now Sony is getting ready to start shipping cells rated at 3.5Ah. The energy density has increased from 182Wh per kg to 226Wh per kg, although the new cells are slightly heavier than the current ones at an additional 10g per cell.

The new cells can also be drained for more power than the current cells, as where the current cells have a cut-off point at 3V the new cells can go all the way down to 2V while still delivering 3.5Ah. Another bonus is that the new Nexelion cells are less temperature sensitive and won't suffer from premature discharging at low temperatures, something that is a problem for Li-Ion batteries.

Sony should start shipping the new battery cells shortly and they should appear in battery packs for various notebooks and several other types of products like camcorders and what not. It'll be interesting to see how much difference in notebook battery life Sony's new Nexcelion cells make and let's hope Sony has managed to improve the reliability as well, so we don't get any more of those nasty exploding battery packs.
