We've had 3 major changes in battery chemistry in the last 45 years. Energy density, lifespan, cost, and dangerous materials have all generally improved. We also have 2 new battery technologies in the process of becoming generally commercially available. Also, batteries went from 500 mAh batteries about the size of your smartphone to 3000 mAh as a minor component of that same smartphone, about an order of magnitude in energy density.
