Journal It doesn't come easy's Journal: Lithium-Ion battery with unprecedented performance 1

A press release from A123Systems announces a new lithium-ion battery technology that delivers unprecedented performance (according to them). The technology is suppose to deliver 10 times the cycle life and 5 times the power over conventional lithium technology, and only require 5 minutes to recharge to 90% capacity. And this is not a theoretical announcement -- the first batteries are now in production and being delivered to the Black & Decker Corporation, who will be utilizing them in a new line of DEWALT branded power tools. The company is also working with the U.S. Department of Energy as part of a major undertaking to develop battery materials for future use in hybrid electric vehicles. Assuming 5 times power means 5 times range (may not be the case but hey let's dream a little, ok?), an all electric car that only had a 70 mile range would be able to go more than 300 miles between charges and only take 5 minutes to recharge at the station. Might this make fuel cell cars (and hybrids) obsolete before they even get started? On a side note, there have been other promises of breakthroughs for lithium based batteries before...wonder if there is a patent lawsuit in the making? This press release is also mentioned over at Green Car Congress.

    I could use that. Batteries are heavy. Lighter batteries are a good thing. 5 times lighter batteries are very good thing.

    I wonder how well this performs in a high radiation environment....

This is the theory that Jack built. This is the flaw that lay in the theory that Jack built. This is the palpable verbal haze that hid the flaw that lay in...
