A 12 months after first deliveries of prototype solid-state batteries to its automotive companions, QuantumScape is receiving extra reward from PowerCo – the battery-focused subsidiary of Volkswagen Group – for the potential of its know-how. PowerCo lately accomplished an endurance check of QuantumScape’s solid-state cells and decided that they may sooner or later energy EVs that may journey 310,000 miles with out nearly any lack of vary.
QuantumScape ($QS) is a complicated battery know-how firm that has been working for greater than a decade to develop scalable, energy-dense solid-state battery cells that may energy EVs in a single day which might be safer, cost quicker, and go farther.
Throughout QuantumScape’s time in solid-state battery improvement, the Volkswagen Group has been a companion from the start and stays one of many startup’s largest traders. OEMs like Volkswagen have helped QuantumScape proceed improvement and ship among the most promising solid-state battery know-how within the trade.
In December 2022, the corporate delivered its first batch of 24-layer solid-state cells to its automotive companions for testing, together with Volkswagen Group and others. Since then, we have seen QuantumScape develop even higher-energy cells and, as of October 2023, exceed efficiency targets in testing.
Not too long ago, Volkswagen Group’s battery subsidiary PowerCo accomplished its personal endurance testing with QuantumScape’s 24-layer cells and studies encouraging outcomes for future electrical automobiles that may provide higher vary with considerably much less battery degradation.
VW Group proud of QuantumScape’s SSB vary
In accordance with a report from PowerCo, it has formally confirmed the efficiency metrics beforehand shared by QuantumScape, bringing longer-range EVs even nearer to scaled deployment. The battery firm underneath the VW Group umbrella has detailed its sturdiness testing course of, which passed off over a number of months in its laboratory in Salzgitter, Germany, and put the solid-state cells by greater than 1,000 charging cycles.
The end result was a battery that retained greater than 95% of its authentic capability. Primarily based on that knowledge, PowerCo states that an EV with a WLTP vary of 500-600 km (311-373 mi) geared up with the QuantumScape cells can journey roughly 500,000 km (~311,000 mi) with none noticeable lack of total vary.
Whereas trade commonplace targets for solid-state cells at this stage of improvement are 700 cost cycles and a most capability lack of 20%, PowerCo states that QuantumScape’s solid-state cell exceeds these expectations, confirming the developer’s personal outcomes described in its report. Third quarter letter to shareholders. The energy-dense cells additionally met or exceeded different check standards, equivalent to quick charging capabilities, security and self-discharge. PowerCo CEO Frank Blome stated:
These are very encouraging outcomes that impressively help the potential of the solid-state cell. The final word results of this improvement could possibly be a battery cell that allows a wide variety, could be charged tremendous rapidly and nearly doesn’t age. We’re satisfied of the solid-state cell and are working at full pace on sequence manufacturing along with our companion QuantumScape.
PowerCo stated the uniform cell idea design developed for the Volkswagen Group is already appropriate to accommodate QuantumScape’s solid-state cell know-how. The subsequent step will probably be to excellent and scale up the manufacturing processes as each corporations intention for scaled manufacturing of solid-state batteries – thought-about by many to be the ‘holy grail’ of electrical mobility.
QuantumScape nonetheless has a variety of work to do earlier than viable, scaled manufacturing could be achieved, however VW plans to proceed its help now within the hope of sooner or later delivering long-range solid-state EVs. In accordance with QuantumScape founder and CEO Jagdeep Singh:
These outcomes from Volkswagen Group’s PowerCo assessments reveal that QuantumScape’s anode-free lithium metallic cells are able to distinctive efficiency. Whereas we nonetheless have to do extra work to convey this know-how to market, we aren’t conscious of every other automotive-sized lithium-metal battery that has demonstrated such excessive discharge power retention over an identical variety of cycles underneath comparable circumstances. We’re excited to work carefully with the Volkswagen Group and PowerCo to industrialize this know-how and convey it to market as rapidly as doable.
