Quantumscape has shared new data showcasing further development of its solid-state batteries, whose cells have completed 400 consecutive 15-minute fast-charge cycles, replenishing from 10% to 80% capacity while still retaining over 80% of the initial ener

QuantumScape ($QS) is a solid-state battery manufacturer founded in 2010 with the goal of developing scalable, effective solid-state batteries. By utilizing millions of dollars in funding from major automakers like Volkswagen Group, as well as a reverse SPAC merger with Kensington Capital Acquisition, Quantumscape has established itself as one of the global leaders in solid-state battery development.

In December of 2020, the battery developer announced a “major breakthrough” in its technology by utilizing a ceramic separator, leading to the successful testing of single-layer prototype cells. After doubling the size of its initial pilot manufacturing line, Quantumscape revealed it had also developed a ten-layer cell.

The battery developer continues to work on multiple layer solid-state batteries before test cells are produced on its QS-0 pre-pilot production line in 2023. In the meantime, however, Quantumscape has reached another industry first with its single-layer solid-state batteries, sharing new charge cycle data.
