QuantumScape (NYSE: QS) saw a 35% increase in shares, while the S&P 500 and Nasdaq gained 0.8% and 1% respectively. The company announced a major milestone in developing its solid-state lithium battery, integrating its Cobra separator process for faster, more efficient production, claiming a 25x improvement over previous processes.

QuantumScape’s stock is down over 90% from its 2020 peak due to past failed promises. With potential disruption in the market with solid-state batteries, competition is fierce. The stock’s future is uncertain, and investors should exercise caution unless they have a high-risk tolerance.
