I took on the CEO role last year because I see QuantumScape as the global leader in solid state battery technologies with an ability to revolutionize energy storage and create tremendous shareholder value in the process.

QuantumScape’s planned first commercial product, QSE-5, is a ~5 amp-hour cell designed to meet the requirements of automotive applications. Here, we’ll walk through the various elements of the cell specifications and explain some of the complexities behind the seemingly simple metric of energy density.

As lithium-ion batteries have become ubiquitous, their safety risks have increasingly been a focus of public concern.

. In this blog article, we’ll look at battery safety testing and do a deep dive into a couple of key test results from energy-dense 24-layer QuantumScape prototype cells based on our Alpha-2 design.

You can find lithium-ion batteries in everything from electric vehicles to mobile phones. But, different applications have different requirements when it comes to the characteristics of the battery format, and EVs are a particularly challenging use case.

QuantumScape’s solid-state lithium-metal battery technology is designed to deliver disruptive improvements to electric vehicle performance.

There are many factors to consider when evaluating a battery’s energy density — but it’s not as straightforward as it may seem.

There are many factors to consider when evaluating a battery’s energy density — but it’s not as straightforward as it may seem.

Using better active materials and optimizing the use of inactive materials are primary ways to improve energy density.

QuantumScape’s solid-state lithium-metal battery technology is enabled by our proprietary ceramic solid-electrolyte separator.

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

    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

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.
