In a previous life I was slightly involved with some of the largest lead-acid batteries there are, the ones in Submarines.
I have friends that are well, deeply involved (up to, and including the Navy's Main Battery Steering Committee)
They have been very -VERY- interested in Lithium-Ion battery as a "some-day" replacement for lead-acid battery

Still? Lithium-Ion doesn't play well with salt water environments and then there's the run-away event the Navy had on one Submarine that was testing them. Sure had the rest of us who used Lithium-Ion on other military projects scrambling with additional testing, reports, meetings, presentations, etc.
