The problem with batteries isn't so much the cost as their weight. There is a limit to the power density of current battery technology and nothing really in the pipeline to greatly improve on this.
So installing a higher-capacity battery also means having a heavier car, which in turn requires more power to keep it moving.
- toomuchtodo 13y agoI'd love to have a gentleman's bet on this :) I bet you a beverage of your choice (I know we're not all craft beer aficionados) that within 10 years, the cost of batteries will have halved, and their capacity will have doubled. I try to put my money where my mouth is; when Tesla went IPO, I bought several thousand shares of stock. I'm holding for the long term, as I think they're not just going to revolutionize mobility, but also battery technology.
