"Plus, the battery pack created during the research was 50 percent smaller than a conventional lithium-ion battery." So can we just keep the battery the same size and now it has 1000 mile range? And - (knows nothing about EV battery technology) - these batteries are liquid cooled, no? Is there no solvent they can run through the battery to "clean off" the crystals that develop?

The battery in a Tesla is about 25% of its weight. So, going to a battery that’s 50% of the current battery’s weight (assumption #1: smaller = equivalently lighter) would cut about 12% of the car’s weight in batteries alone. I guess designing the car around those lighter batteries can get you a total decrease in weight of around 20%. If so, and assuming that’s a similar decline in energy used per kilometer, a 50% smaller and lighter battery already can give you 25% more range.
