Did you read the article? If you understand economies of scale and can read the graph, you'll understand why it's electric cars causing this new development in battery technology. From 1939 to 1945, the world saw the greatest change in weapon technology it had ever seen, topped off with the atomic bomb. That weapons technology was not spawned because people wanted to go hunting. It was because governments around the world poured money into weapons research.
Your mistake is to assume that no one desperatly pumped R&D ressources into battery technology in the last 40 years until Elon Musk decided to write a blog about it. Its not like lap tops/mobile phones/air planes are in need of lighter and more efficient energy storage technologies too, right? Oh wait, my fault. Economics of sale. Iphones sell like **** compared to EVs.
Both electric motors and battery technologies are already well researched, what's new now is their application for EV/HEVs.
