No salary listed
Thornton, CO, USA
The job is onsite at Solid Power. The specific address is not provided in the job posting.
Solid Power develops and produces all-solid-state battery cells aimed at enhancing the electric vehicle (EV) market. These batteries are designed to be safer, provide higher energy density, and be more cost-effective than traditional lithium-ion batteries. The technology utilizes sulfide-based solid electrolytes, which allow for efficient ion movement and easier manufacturing, resulting in lighter battery packs with longer ranges and lower costs. Solid Power collaborates with major automotive companies like BMW and Ford, and has partnered with SK Innovation to scale production. The company aims to transform energy storage solutions and support the growth of e-mobility.

Wednesday, 21 May 2025The BMW Group is bringing large-format, pure ASSB cells from Solid Power to its test vehicle, a BMW i7, being operated in the Munich area, introducing the potential benefits of ASSB technology – higher energy density in a very compact storage system compared to current technologies.Since 2022, the BMW Group and Solid Power have intensified their activities with regard to the development of ASSB technology, through a transfer agreement. With a higher energy density compared to current battery technologies, ASSB batteries have the potential to achieve longer ranges in vehicles without the disadvantages with regard to the weight of the overall storage system.“Solid Power is extremely proud that our partnership with BMW has resulted in the first demonstration of truly all-solid-state battery cells in a vehicle” said John Van Scoter, President and Chief Executive Officer of Solid Power. “We believe in the promise of ASSB’s and continue to drive innovation of our sulfide electrolyte in support of that future for EV’s.”The concept battery integrated in the BMW i7 test vehicle combines Gen 5 construction principles (prismatic cells in modules) with new module concepts for integrating ASSB cells from Solid Power.“Our BMW i7 ASSB test vehicle on the road is a perfect example of the BMW Group's technology-open mindset” added Martin Schuster, Vice President Battery Cell and Cell Module at the BMW Group. “We are continuously advancing the development of new battery cell technologies and are constantly expanding our know-how with valuable partners such as Solid Power. ”The management of cell expansion is to be tested along with questions around how to control operating pressure and adjust the temperature conditions.The use of solid power cells with sulfide-based electrolytes and their complete integration into a battery pack will provide the BMW Group with further important findings in the test programme over the coming months.The cells were developed and manufactured by Solid Power in collaboration with experts from the BMW Group. Further development steps are required to implement ASSB technology in a competitive overall storage system.The BMW Group and Solid Power have been cooperating since 2016 through an extended “Joint Development Agreement”, which was supported by BMW Group's investment in Solid Power in May 2021 as part of a financing round.At the end of 2022, BMW and Solid Power agreed to further deepen their partnership
Solid-state batteries are in focus these days. It is steadily gaining traction with consumer electronics and electric vehicles, constituting the largest share of the global solid-state battery market in 2022. Researchers estimate that solid-state battery applications in the EV sector will grow exponentially in the next decade, reaching a market size of US$4.3 billion by 2032. There are reasons why solid-state batteries are poised for exponential growth. Essentially, they refer to a battery technology that uses a solid electrolyte instead of liquid electrolytes, as used in lithium-ion technology. Solid-state cells consist of a cathode, a separator, and an anode. The cathode could be made with the same compounds as a lithium-ion battery
BMW has partnered with Solid Power to develop solid-state batteries for future electric vehicles.
High-capacity batteries that charge faster and last longer are key to powering the future of portable electronics, electric vehicles, and long-term energy storage.For the past few decades, lithium-ion batteries have been leading this sphere. A type of rechargeable battery, lithium-ion batteries are charged and discharged by the movement of these ions between the positive electrodes and negative electrodes, i.e., anodes and cathodes.The metal lithium used in these batteries is soft, silvery, and highly reactive. It has the lowest density of all metals and is found in compounds as a mineral, with Chile being its biggest producer. Chile also has the largest lithium reserves, followed by Australia and China; the latter is also a leader in lithium-ion batteries.These batteries actually require huge amounts of water and energy to produce. They are also very difficult to recycle.So, while lithium-ion batteries have proven their performance in portable consumer electronics like smartphones, laptops, and other handheld devices, as well as EVs and storage systems for solar power backup, the market is now searching for materials that can outperform lithium-ion and power the next-generation of devices, long-range vehicles, electric aircraft, and grid-level storage.This has led researchers to aluminum, which shows promising performance for safer, cheaper, and more powerful batteries.Aluminium's Potential in Advancing Batteries Efforts to develop rechargeable aluminum batteries have been going on for many decades now but gained significant traction in the past decade or so. Increased attention and research have helped Al-ion batteries achieve exceptional rates in charging and discharging. All the developments surrounding Al-ion batteries are significant due to the superior benefits this electropositive metal brings to the table. Aluminum's unique properties include being lightweight, corrosion-resistant, and having high thermal conductivity. This versatility has made this metal highly beneficial in a wide range of applications in various industries, notably transportation
Solid-state batteries are an emerging technology that is expected to revolutionize energy generation and storage. These batteries have the potential to redefine how we power our electric vehicles (EVs) and even smartphones by being safer, charging faster, and storing more energy.These batteries convert chemical energy into electrical energy by using a solid electrolyte, which is a material involving a solid matrix with high ionic conductivity, to move lithium ions from one electrode to the other. This is unlike the currently popular lithium-ion batteries, which use liquid or gel electrolytes.Having a solid electrolyte allows these batteries to have a long shelf life because solid systems are more stable, can operate efficiently over a wider temperature range, and are non-flammable, making them safer.But while solid-state batteries offer greater durability, versatility, and a higher energy capacity, they are not widely produced yet. That is because of the challenges they face in terms of cost and scalability, which researchers are actively trying to overcome. Several companies are also investing heavily in the hopes of taking it commercially in the next few years.Best Investable CompaniesSo, let's take a look at some prominent companies, their unique technology, financial performance, and how far their tech is from reaching the market.The California-based QuantumScape Corporation is one of the best ones out there when it comes to the development and commercialization of solid-state lithium-metal battery technology for EVs. Their focus is on making battery production economical and accessible for adoption in various markets, including consumer electronics.The company's battery technology is designed to offer faster charging, greater energy density, and enhanced safety.Making a battery better than lithium-ion, however, isn't easy; rather, as QuantumScape's chief technology officer Tim Holme has pointed out, it's “really hard.” It actually took them $100 mln and five years just to choose the right material for the solid electrolyte
