I know it is Slashdot and the summary is misleading about it "adding 100kg over a Tesla battery" but if you actually read the article you would learn that the idea is not to replace the existing Li-ion battery but to have this as well as a reserve. As you point out most people only drive short trips for which a Li-ion battery is well suited. This is just to provide a power for long distance driving.
Or, you know, if people would just actually read the summary, which states that the Li-ion battery would still be retained for short-range trips...
I'm sure I could have worded the 100kg bit better to state that the 100kg is IN ADDITION TO the existing weight of the Li-ion battery... but I guess
