| Rather better article than usual about batteries and where battery tech is heading. http://www.theregister.co.uk/2013/05/28/hot_lithium_ion_batts/ It makes a refreshing change from the usual breathless hype of the (mainly) US tech blog coverage to see some real science and facts in there. The downside is that game changing battery tech is probably going to stay a permanent 30 years out. While there are a few more cycles of incremental change to be had, it won't give us the factor of 10 improvement we need. The available 20-30% improvement is still useful, especially if the costs can come down as well. This in turn means that we need to focus on reducing energy needs in battery powered devices as much as increasing the storage capacity. That's a good thing in itself. And for E-bicycles, I want the lifespan and relative safety of LiFePo, with the size, weight and high current capability of RC LiPo (LiCo) at about a 1/3 of the price. m'kay?   Hot new battery technologies need a cooling off period • The Register »Scientists began buzzing about electrochemical energy cells in the 18th century; consumers bought their first low-density Lithium-ion batteries in the late 1980s, and industry became hooked on the things in the 1990s. Ever since, the comedy electronic-device conflagration has been as much a ... [from: Google+ Posts] |
