That's the first I've heard of massless batteries. Fascinating.
Definitely the first time I've heard of the excellent marketing term "massless battery", but I've seen structural batteries mentioned before. There was an Ars Technica (actually Wired) article last year about them here .
The commenters quickly found some major issues with the idea - it'd be harder to recall/replace/recycle batteries since they're now part of the chassis and not detached commodity parts, body damage turns into a dealer-level repair since you're not just welding/bending metal anymore, it's harder to cool/heat them if they're not all in one place, etc.
Definitely valid criticisms, also what the hell happens in an accident to these structural batteries in a vehicle? Are they a fire or explosive hazard, how much more dangerous is it for the passengers (vs gas tank/fuel cell/battery pack) or people outside the vehicle, etc. etc.
All questions that can be answered, and structural batteries sound useful enough that they will probably spend the time, money and brain power to mitigate or solve all of those sorts of problems.
Bring it on, my next car/truck is going to be electric for sure, unfortunately these probably won't be available by the time I have to buy something.
