We recently published 10 Stocks Stole the Show, 5 Hit Historic Highs. QuantumScape Corp. (NYSE:QS) is one of the best performers on Thursday..

QuantumScape extended its rally for a second day on Thursday, climbing 18.23 percent to close at $12.13 apiece on strong investor confidence after taking center stage at the demonstration of the Ducati V21L prototype that runs on its solid-state battery cells.

The showcase highlighted significant improvements in battery chemistry and charging performance, with the cells able to charge between 10 and 80 percent in just around 12 minutes, as compared with today’s EV charging, which takes up to hours to fully charge.
