    New battery announced

    I read an article today about a new battery that has 10X the power density of the Li ion batteries now being used. Plus, has a projected life of 1000 recharges. So that would be a Tesla Model S with 3,000 mile range and a battery life of three million miles. Of course, it is not in production yet, and there are safety issues that still need to be resolved. But I think better batteries are definitely on the way. Here is a link to the article.

    • Most likely we will see this kind of tech in military applications, then small consumer devices like cell phones, smart phones, etc. Meanwhile, incremental improvements in anodes, cathodes, electrolytes have taken place that increase Li-ion battery capacity by 20-30% - from Panasonic. Some of this stuff is selling. I suspect Tesla likes to evaluate the battery for safety, reliability, cost versus benefit, etc. These incremental improvements will help MS and MX. Not enough to drive price down for the mass market.

    • The article doesn't say anything about the number of recharges. It says it can be recharged 1000 times more quickly. Assuming you had a source that could feed that much power into your car (1.21 gigawatts!), then what would have been a 10 hour charge could be accomplished in 36 seconds.

      I hope such things come to pass, but I wouldn't hold my breath. We've seen far to many breakthroughs that take forever to commercialize, or don't scale up from lab experiments.

    • (sarcasm) but everything I learned from JP told me this was an impossibility...It's chemistry! (/sarcasm)

      Sentiment: Buy
