QuantumScape Battery Technology Advancement
Can be combined as current density
Challenge: The "AND" Requirements Test
Historically, solid-state batteries haven't been able to meet all simultaneously
No single accepted standard test since batteries have different requirements and operating conditions are so varied
For EV market, a good start is a simultaneous test of:
QuantumScapeⓇ
