OPmobility and ProLogium have signed a memorandum of understanding to collaborate on solid-state EV battery packs. Their goal is to integrate ProLogium’s solid-state cells into battery modules and packs for electric vehicles. The companies are focusing on developing a standardized battery module solution. This solution is intended for use by automakers on various electric vehicle platforms in the future. ProLogium will supply the solid-state cells, which OPmobility will then test. OPmobility will also handle the design, development, and manufacturing of the resulting battery modules. Technical Validation of Entire Battery Architectures In the industry, solid-state batteries are regarded as a potential key technology for future electric vehicles. The potential benefits include improved range, charging efficiency, and safety. However, achieving these characteristics in the vehicle does not depend solely on the cell. The integration of these components at the module and pack levels is also crucial. This is precisely where the collaboration comes in. The two companies aim to investigate how the advantages of individual cells can be translated into concrete battery architectures. Their goal is to provide automakers with more reliable data on the performance of such systems. At the same time, they intend to accelerate the development of integrated solutions. According to the companies, the memorandum of understanding aims to establish joint testing and engineering standards. The process will begin with performance tests and the development of battery modules. Subsequently, vehicle integration will be based on these results.

According to a Reuters report, General Motors may change its plans for the batteries in its future electric vehicles.  The company’s head of batteries, Kurt Kelty, revealed that the U.S. automaker is considering excluding LFP cells from its EV portfolio. Previously, GM had announced plans to develop lithium iron phosphate (LFP) batteries for future electric vehicle models. Production was scheduled to begin in late 2027 at a jointly operated plant in Tennessee. However, GM is now shifting its focus toward lithium-manganese-rich (LMR) batteries. The company apparently views this cell chemistry as the more important technology for higher production volumes. According to GM, LMR cells in the U.S. are expected to cost roughly the same as LFP cells but have a higher energy density. The Tennessee plant is set to begin producing LFP cells this month. However, these are intended for stationary energy storage, not electric vehicles. Strategy deviates from market trend Avoiding the use of LFP cells in electric vehicles would set GM apart from many competitors, who use LFP cells to reduce costs and offer more affordable electric vehicles. Several manufacturers use LFP cells to reduce costs and offer more affordable electric vehicles. These include Tesla, Rivian, and Ford. Chinese manufacturers adopted the technology on a large scale early on. LFP batteries are considered cheaper, more robust, and safer than many nickel-rich cell chemistries. However, their lower energy density can lead to shorter ranges. GM has used more powerful nickel-rich batteries in more than a dozen U.S. electric models so far. The new Chevrolet Bolt, on the other hand, is expected to use LFP cells from the Chinese company CATL.

General Motors and Peak Energy plan to develop sodium-ion battery cells for stationary grid storage. This initiative is based on a strategic partnership that includes an investment by GM Ventures in Peak Energy. The goal is to deploy the cells in large-scale energy storage systems. The technology is expected to be ready for mass production in 2028 at the earliest. As part of the collaboration, GM will develop the sodium-ion cell in its Michigan battery laboratories. The company will also retain exclusive manufacturing rights. Peak Energy will then integrate the cells into its own energy storage systems. Passively Cooled Storage as a Cost Advantage According to Peak Energy, the company is focusing on passively cooled storage systems. These systems are designed to operate without the energy-intensive active cooling common in many lithium iron phosphate systems. Peak Energy claims its sodium-ion systems could reduce storage costs by 20 percent compared to conventional systems. GM Seeks Additional Uses for Battery Investments For GM, this move comes during a period of weaker electric vehicle sales in the U.S. The NYT reports that GM and other manufacturers have scaled back production of electric cars. Reasons for this include the expiration of tax incentives and heavy losses from previous investments in electric cars. Stationary storage systems could help automakers leverage their existing battery expertise more broadly. Tesla has been selling such systems since 2015, and Ford is planning large-scale battery storage projects as well.
