Battery prototype: Two sludge-like electrode materials are fed into the device shown here. The anode material flows into the top half, and the cathode flows into the bottom. Lithium ions pass from one material to the other, and electrons flow through the black and red leads. Credit: Yet-Ming Chiang
Liquid Car Battery Ping!...........
By definition, higher energy density means a smaller battery — however, it does not necessarily mean cheaper. For instance, lithium batteries have higher energy density than lead-acid batteries — they are also much more expensive.
Them’s some damn big alligator clips (red and black) if that’s really a car battery....
“A startup hopes ...” to make a new kind of car battery?
