They use the same Li-Ion chemistry, but structural composite batteries are on the near term horizon. You get extra capacity "for free" since they also serve as the physical structure of the car/cellphone/aircraft.

That doesn't really help with grid storage.

That sounds potentially incredibly scary if you get into a fender-bender.

  They use LiFePO4 so it's chemically inert, and it's protected from shorting out due to mechanical damage because the entire composite acts as a thermoresettable fuse.

    The next question is how do you repair damage in that scenario?
    - chroem- 8y ago
      Composite structures don't tend to be very repairable in general, but if it's localized damage usually you will just glue a patch in place.

    LiFePo4 also works better in the cold.

How does the structure behave in a fire?
