Hitachi Speeds Into Hybrids with World's Most Efficient Lithium-Ion Battery

[Texas]

Some have written off the Japanese for lithium-ion (OK, only HyperMiler) but it appears they are not out of the game yet.


"According to Japanese Web site Nikkei, Hitachi's battery has an output per kilogram of 4,500 watts--70% more than its current li-ion batteries and 50% more than a new model that will be released next year. The super-battery has a lifespan of 10 years, so it can stay put in a PHEV for life (or close to it).

No word yet from Hitachi on pricing, but the battery, scheduled to be released in mid-2010, will almost certainly be more expensive than its less efficient counterparts. One thing is for sure, though. Li-ion battery makers like Johnson Controls-Saft and Blue Energy should watch their backs. "

A123 can deliver 7,500 watts per kg for 10 secs and 4,500 watts continuous. So what's the big deal - A123 is already in DeWalt battery tools. Of course a Hitachi product will be top of the line.

I am pretty sure they use some form of nano-technology.

Convention activity in the United States and Canada has become a much larger and much more popular trend within the past decade. Larger conventions such as Anime Boston, Otakon and Sakuracon have become renowned internationally. With the added public attention coming from such popular animated cartoons imported from Japan (see anime) including bleach costume and now the popular bleach costumes, cosplayers and the anime world have peeked their heads into the world of mainstream pop-culture, on at least a relatively underground scale. More and more convention goers bleach cosplay as their favorite characters from their favorite anime, and thus, the bleach cosplay costume and anime subcultures have been able to have enough influence to further the creation of List of anime conventions to accommodate for the increasing number of cosplayers. Many cosplayers jokingly refer to Halloween as "National Cosplay Day", although many cosplayers spend so much of the year dressed up, they also like to take Halloween as a day off.
