Why would anyone do that when Tesla already makes full sized vehicles with 100kwh packs?

GCC:
Ford partnering with Solid Power to develop solid-state batteries for next-gen EVs
https://www.greencarcongress.com/2019/0 ... power.html
. . . Solid Power’s solid-state technology combines a cathode, metallic lithium anode, and a safe, inorganic solid electrolyte layer. Solid-state batteries offer improved energy and safety as compared to current industry-standard lithium-ion batteries.

This partnership will heavily leverage Solid Power’s first fully automated, roll-to-roll production facility, which is anticipated to be fully operational in Q2 2019. . . .

Potential benefits of Solid Power’s ASSBs include:
  • Fifty percent higher energy vs. current state-of-the-art (SOTA) lithium-ion, which can increase at the module- and pack-level due to design simplicity.

    Substantially improved safety due to the elimination of the flammable liquid electrolyte as used in lithium-ion.

    Low-cost battery-pack designs through minimization of safety features and simplified thermal management.

    High manufacturability due to significant compatibility with automated, industry-standard, roll-to-roll production. . . .
There's a comparison chart. Biggest issue I see is the minimum operating temp, only 0 deg. C for these batteries (but 150 deg. C max). They claim -20 - +60C for current Li-ion, although most I'm aware of are -30C.
