While true, take note of both the power and energy density. They are not as good as Lithium batteries, though still well suited to stationary applications IMO, e.g. as a buffer for wind/solar, especially as they are likely to be much cheaper than Lithium if manufactured in bulk. >This subject may be common knowledge to many on this list, but I was unaware >of it. I was wondering if the lithium in the batteries we all use could be >replaced with sodium so I just did a web search (I, like many, no longer >google) and found there has been considerable research going on in that >direction. > >Improvements in the structure of the "hard carbon" electrodes bodes well for >the future of this type of battery.
