Doesn’t mean they are going to make a new and better battery.
Time well tell.
It also doesn’t mean that the materials they found will work outside laboratory conditions. They may very well have found materials that will form a battery with the same work efficiency as gasoline, 12,000 watts per gallon. However, it might cost $150,000/battery to create.
True.
But they might find battery types that might, or if not as well, may be acceptable for certain types of commercial applications where it could be worth it to produce.
