QuantumScape unveiled on Tuesday afternoon the data about its new solid-state battery technology in a video presentation, revealing impressive results with long-range capacity and especially fast-charging.

In its video, QuantumScape showed that the core of this achievement has been a ceramic separator that the company has been working on for several years. It created the new material in the year 2016 and worked on making it manufacturable at scale with a low defect rate.

Considering that the data is proprietary information, QuantumScape didn’t reveal too much about the material other than it’s ceramic-based and uses four precursors that are available commodities.

The company also showed in its video presentation actual test results, showing that QuantumScape’s new battery cells can charge from 0 percent to 80 percent capacity in only 15 minutes.

The video presentation received praise from battery experts including Tesla co-founder JB Straubel, who said on his Twitter account that the results represented a “major breakthrough,” pointing out that QuantumScape has shown that it can retain over 80 percent capacity after only 800 cycles.
