![]() ![]() With 24 layers, each comprised of a solid-state separator, cathode, and a lithium-metal anode, QuantumScape states that its prototype cells have capacities in the “multi-amp-hour range.” With initial deliveries underway, OEMs like Volkswagen Group for instance, can begin their own internal testing of the solid-state batteries as they pertain to EVs and provide feedback on their performance. While this milestone brings us closer to our ultimate goal, there’s still a lot to do before this technology becomes a commercial product, and we now turn our attention to this important work. I’m proud of our team for all the effort and determination that went into achieving this milestone, especially in light of the challenges we encountered this year. Per QuantumScape CEO and cofounder Jagdeep Singh: View all commentsĪll that said, QuantumScape is the first to admit it still has a long way to go before solid-state batteries become commonplace within EVs and other electronics. Independent testing means we will know if these batteries are as good as they sat. I never can fully trust reports that are just from a research department of the company that plans to sell an item, they always will use the best terms they can get away with. I am glad that samples have been sent out to others for testing. The company shared details of the initial deliveries in a press release today, capping off another impressive year of development. ![]() First solid-state EV batteries reach OEMs for initial testingĪs promised, QuantumScape delivered its 24-layer solid-state EV batteries to OEMs before year’s end. Today, QuantumScape has delivered the first A0 prototype solid-state batteries to EV automakers for them to test themselves. Each major sampling stage (A,B, and C) will consist of several generations of maturing cell prototypes which will be delivered to OEMs for testing and validation. These first 24-layer prototypes have been labeled Sample A cells, representing the beginning of a three step journey toward automotive qualification and eventual production. This past February, QuantumScape shared another industry first with a single-layer cell that had completed 400 consecutive 15-minute fast-charge cycles, replenishing from 10% to 80% capacity while still retaining over 80% of its initial energy.īy Q2 of 2022, the company was touting energy dense, 24-layer cells, which were already enduring internal testing. After doubling the size of its initial pilot manufacturing line, Quantumscape revealed it had also developed 10-layer cells, followed by a 16-layer prototype. This led 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 that achieve cost parity with traditional lithium-ion cells popular in current EV models.Īfter over a decade of research and development, the battery developer really started gaining momentum in 2020 when it announced it had reached a “major breakthrough” by utilizing a ceramic separator. Referred to as “Sample A0,” these cells represent QuantumScape’s most impressive solid-state technology to date, and their delivery marks a key milestone in its journey toward full integration of energy dense, fast-charging cells into future electric vehicles. Everyone seeks for new technologies and maybe even some breakthroughs as it's already clear that there is no other way than electrification.Solid-state battery manufacturer QuantumScape announced that its first 24-layer lithium-metal prototype sells to EV OEMs for testing. It appears that the battery start-ups are attracting large OEMs, as we are getting more and more news about new deals or investments. ![]() The JDA allows the partners to respond to opportunities from automotive manufacturers seeking to achieve next generation performance." Each of the partners has expertise in manufacturing as well as research and development. To improve battery performance, the partners need to understand how the materials would behave in assembled batteries, so the collaboration between PPES and Nexeon is an ideal partnership to accelerate the development. "Silicon materials are important for PPES, and are a key component in achieving new battery designs. Many manufacturers have already added silicon to the anodes, but as far as we know, the full potential has not been reached yet. The problem is to bridle the silicon - which expands, breaks and degrades the electrode - so it would not affect the longevity or charging times. ![]()
