Here’s another update as it pertains to automakers actually testing solid-state batteries: Not just simultaneously, but dramatically (see graph above).Īccording to QuantumScape, it has five consumer sampling agreements, three of which are with top-10 automotive OEMs, one of which has already reserved at least 5 MWh of capacity on the QS-0 pre-production line. However, its solid-state lithium-metal technology offers the potential to improve both. In the letter, QuantumScape admits it does not believe it’s possible to improve both the power and energy of battery cells simultaneously given their current chemistry. QuantumScape can offer updates to battery power and energy The A sample is planned to have dozens of layers and is intended to demonstrate the core functionality of the battery cells. We continue to target delivery of A-sample cells to at least one customer in 2022.

In Q2, we aim to complete production qualification for the majority of the tooling for the Phase 2 engineering line, including automated cell assembly tools, ultrasonic welders and cell testing systems. We can explain the rest, but QuantumScape offers its own production line updates best: This line remains on track to produce candidate B-sample cells in 2023 (B samples are made using production processes).QS-0 Pre-Pilot Production Line – Planned to feature film production in large continuous kilns with automated film handling and cell assembly.Phase 2 Engineering Line – Builds upon the capabilities of Phase 1 but integrates larger-scale equipment with higher levels of automation.Phase 1 Engineering Line – QuantumScape’s current core of development capabilities to date (supports R&D, process development, and pre-A sample customer sampling).Speaking of which, the battery developer also shared a detailed strategy of its initial scaling of production capacity. This increase was made possible by QuantumScape’s updates to production tooling on its Phase 1 engineering line. This past quarter, the company recorded average weekly starts over 3,700, up from 2,000 in Q4 of 2021.

QuantumScape also offered updates to the scale of its operations, including a ramping up of separator production – a key goal for 2022 to reach weekly starts over 8,000. The company describes this initial cell as “an encouraging proof of concept” for the flexible format but admits much work still needs to be done before it can truly be commercialized. In addition to containing more layers, this new cell is the first to showcase QuantumScape’s proprietary cell architecture, which is flexible enough to support an anode-free format. So far, the cell’s energy retention and cycling have behaved similarly to the cells that came before it (see graphic above). The 16-layer solid-state cellĬontinuing its trend of developing and testing multi-layered cells that perform under the company’s “gold standard” conditions, QuantumScape shared that it has developed a 16-layer solid-state battery cell that has already endured over 500 charge cycles.

The details can be rather … dense, so we recommend checking out the full letter for yourself, but here are some of the key takeaways. The following information was taken from QuantumScape’s quarterly letter to shareholders recapping Q1 of 2022. Source: QuantumScape The latest QuantumScape updates In its latest Q1 letter to shareholders, QuantumScape has continued its momentum with a bunch of additional solid-state updates. In February, QuantumScape shared another industry first with a single-layer cell that completed 400 consecutive 15-minute fast-charge cycles, replenishing from 10% to 80% capacity while still retaining over 80% of its initial energy. After doubling the size of its initial pilot manufacturing line, Quantumscape revealed it had also developed a 10-layer cell. In December of 2020, the battery developer announced it had reached a “major breakthrough” in its technology by utilizing a ceramic separator, leading to the successful testing of single-layer prototype cells. QuantumScape ($QS) is a battery technology company founded in 2010 with the goal of developing scalable, effective solid-state batteries.
