What this means for investors

QuantumScape will be teaming up with Honda on a new joint research program for its solid-state battery technology. As QuantumScape advances toward validation of the technology and manufacturing capability at scale, investors are gaining optimism about the total addressable market.

Honda isn’t just an automaker; as a partner, it could be a solid-state battery customer for its power equipment as well as for electric cars and motorcycles.

QuantumScape also has a partnership with Volkswagen (VWAGY 0.90%). Earlier this year, QuantumScape debuted a Ducati motorcycle featuring its battery technology. Ducati is part of Volkswagen’s Audi division.

Investors were scooping up QuantumScape shares today, seeing more opportunity beyond EVs once it fully commercializes its solid-state batteries.
