Hello!<p>Last ditch effort here - a year ago or so there was posed a link to a page which had wonderful visual and text descriptions of different battery technologies and their tradeoffs. It illustrated 5-6 different dimensions which one might optimize for (e.g. charging speed, capacity, cost, lifetime, etc) on these little charts which looked a bit like spiders' webs.<p>I thought that was a great resource, but didn't save it at the time. Anyone know what I'm talking about or have a link? Thanks!
