QuantumScape is developing solid-state lithium metal anode batteries to make long-range, mass market electric vehicles faster charging, longer range, and more affordable. Software has been a key enabler of rapid learning that has spanned new materials discovery through production quality control. QuantumScape has deployed many different models of varying complexity up to neural networks for image segmentation. Working under the constraints of smaller data (10s to 1000s of labels) in a small team of developers has taught the value of empowering expert users to label data and construct their own models.
