Rechargeable lithium-metal batteries have been the subject of intense research for decades, and today they seem closer than ever to reaching the marketplace.

Check out this article written by the experts on solid-state battery technology, QuantumScape, to learn about coulombic efficiency in electric vehicles.

Fast charging is increasingly important to buyers of electric vehicles, but high-energy legacy lithium-ion batteries are still limited in how fast they can recharge. These limitations are largely due to fundamental constraints

In the simplest terms, a battery’s capacity describes how many electrons it can store for later use.

In our blog post on sulfides, we outlined some of the limitations we believe make sulfide-based solid electrolyte separators unsuitable for enabling lithium-metal anode technologies.

A critical factor drivers consider when looking at electric vehicles is how quickly they can be charged. Unfortunately, battery experts can use confusing jargon when talking about this concept, so here we’re going to break down key charging concepts and how they translate to the real world.

This report from Mobile Power Solutions, an independent battery laboratory, validates QuantumScape battery cell performance.

Today’s electric vehicle battery market is characterized by various technologies and chemistries, addressing different user requirements.

Why do electric vehicles heat up the battery before a fast-charging session but run cooling systems while cruising? Why do EVs lose range in the cold winter months – and how can QuantumScape’s battery technology overcome these challenges?

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?

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.

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.

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.
