Why QuantumScape Stock Surged Today

Aspiring electric-vehicle battery maker QuantumScape (NYSE: QS) doesn't have a product yet and is still years -- rather than months -- away from potential commercialization. QuantumScape believes it has a ceramic material that can be used as a solid-state separator in a battery cell to help overcome slow charging times, and improve performance and safety versus current lithium-ion batteries. Earlier this year, QuantumScape announced it had successfully built its first multilayer battery cell with four layers -- a milestone showing the technology is feasible.
