| TechReview: Behold the Lithium Air Battery |
| 2009-06-30 |
| A company based in Berkeley, CA, is developing lightweight, high-energy batteries that can use the surrounding air as a cathode. PolyPlus is partnering with a manufacturing firm to develop single-use lithium metal-air batteries for the government, the use of these batteries would be, at first, limited to underwater vessels and it expects these batteries to be on the market within a few years. The company also has rechargeable lithium metal-air batteries in the early stages of development that could eventually ten years + probably power electric vehicles that can go for longer in between charges. The single-use batteries made by the company employ a piece of lithium metal about two centimeters squared and three millimeters thick; they have a storage capacity close to that of the lithium-ion batteries in today's laptops at one-fifth the weight |

| #3 energy to weight ratio is better with Li theoretically the energy density will also be better |

| #2 Saying "Lithium" is much cooler than saying "Zinc...." |
