It is funny, in the Solar business, many are considering Li-Ion. The charge controllers are not setup to properly charge Li-Ion. For Solar, since we're not moving (generally), Lead-Acid is still the norm. Although in my applications, my customer requires liquid Nickle-Cadmium batteries, because of life issues.
We are exploring Molten Salt as an alternative to Nickle-Cadmium. If the Sumitomo battery pans out, Li-Ion is done. Twice the power density at 10% of the cost. And with the very long life and high current capability, it might replace lead-acid in starting cars.
