The next GREAT battery invention for electric cars is ALWAYS just around the corner. The problem is that these new batteries never actually make it “around the corner” because the REAL WORLD is vicious to batteries, much more so than it is to gasoline. Temperatures from -40 to 120F have to be accommodated, running at varying loads, especially climbing steep hills slowly in hot weather (which often overheats gas cars too), and the demand that they charge fast, very fast.
Young people and Lover's Lane - leaving the radio/stereo going late into the night - they shouldn't use electric cars.
