Silver Zinc Batteries

Zinc Matrix Power has unveiled its new rechargeable battery technology at the Intel Developers Forum, based on silver-zinc instead of lithium-ion currently used in many modern rechargeable batteries.

They see three main advantages that their amalgamation of silver, zinc and water have over the current technology:

1. Safer: in the light of the recent overheating and catching fire of laptop batteries, this is a major plus
2. Performance: more battery life
3. More environmentally friendly: battery cells can be easily recycled and reused.

Zinc Matrix Power claims their battery will have twice the energy of a lithium ion battery. According to their technology page, their technology has an energy density of 600 Wh/liter and 240 Wh/kg. This compares to ~250 Wh/L and ~150 Wh/kg for lithium ion batteries according to Wikipedia.

If so, I can't wait for them to be released. The other big question, of course, is how much will it cost?
