The Problem with Sulfides

We are often asked about the basic chemistry of solid-state battery materials. Specifically, what’s the composition of your solid electrolyte, and why did you choose that material over others?

How to Benchmark Solid-State Batteries

Evaluating the performance of new technology can be challenging for experts and the public alike. Internal combustion engines have been around for more than a century, and by now, most people know how to compare them based on horsepower, torque, or fuel economy.

Solid-State Battery Landscape

Following the announcement of QuantumScape’s solid-state lithium-metal battery technology results in December 2020, there has been a lot of excitement in the industry related to the potential of this new technology and the impact it could have on the automotive EV powertrain.

A Discussion of QuantumScape’s Battery Technology Performance Results

At QuantumScape, we have appreciated the surge in interest in solid-state batteries since we revealed our performance data at our battery showcase. We would like to elaborate on a few aspects of the data we presented at the showcase.
