One of the most important points for the decade is to offer the longest battery life time in the smallest enclosure possible. This is true for notebook, but also for handhelds, all mobile devices, transportations or in your car.
Many companies are working in this field to offer competitive solutions. One of them, ZPower announced to have developed a battery bringing 40% more power than the equivalent Li-Ion enclosure. ZPower should launch this next generation of rechargeable silver-zinc batteries for mobile electronics in 2009. In addition to power such battery are also greener as 95% of the primary elements can be recycled and reused. That battery will also be less dangerous and not carry the explosive potential of Li-Ion.
