White paper: A deep dive into QuantumScape’s fast-charging performance

Chart of discharge energy

    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 of battery design. QuantumScape’s technology has been designed to overcome many of these constraints, to unlock a step-change in fast-charging performance […]

Distinguishing charge rates for next-generation batteries

Charge rate chart

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.

Temperature in Battery Development

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?

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.
