Mercedes CTO says solid-state batteries may not be necessary
Solid-state battery technology is widely expected to be the next big thing in the EV world, as it promises higher energy density, lower cost and more safety than current Li-ion designs. However, Mercedes Chief Technology Officer Markus Schäfer recently voiced a contrarian view, saying that solid-state batteries “may not be necessary,” thanks to developments in… Read more »
Nio says it’s ready to use semi-solid-state batteries in production EVs
Solid-state batteries promise improved performance and safety compare to current technology, and they may be getting close to commercial deployment. The latest step forward: semi-solid-state batteries may soon appear in production vehicles in China (sigh…where else?). Chinese battery specialist WeLion has delivered its first semi-solid-state battery cells to EV manufacturer Nio, which plans to use… Read more »
Factorial earns UN 38.3 certification to ship 100 Ah solid-state batteries
Factorial Energy, a Massachusetts solid-state battery developer, has received UN 38.3 safety certification for its 100+ Ah automotive solid-state batteries. The UN 38.3 standard governs the safe transport of lithium-ion and lithium-metal batteries. It includes crush, thermal, vibration, shock, external short circuit, altitude simulation and forced discharge tests that are conducted by a third party…. Read more »
Engineers find a novel way to control dendrite propagation in solid-state batteries
Solid-state batteries are a major focus for battery researchers, as they could offer weight and size reductions, as well as greater safety, compared to current Li-ion designs. However, they have a major drawback: dendrites, root-like structures that build up on the lithium surface and penetrate the solid electrolyte, eventually crossing from one electrode to the… Read more »
New electrode material preserves its volume, solving a major limitation of solid-state batteries
Solid-state batteries (SSBs) offer several potential advantages over current lithium-ion batteries, including improved safety and faster charging. However, SSBs suffer from a problem that limits their durability. When lithium ions are inserted into or extracted from the electrodes, the crystalline structure of the material changes, making the electrode expand or shrink. These repeated changes in… Read more »
Researchers develop method for stabilizing interfaces in solid-state batteries
Researchers at MIT and the DOE’s Brookhaven National Laboratory have developed a method for stabilizing the interfaces between the electrolyte and cathodes in solid-state batteries during the sintering process. Based on research reported in Advanced Energy Materials, the team found that when temperatures are above a few hundred degrees Celsius, carbon dioxide and reactions unfold… Read more »
Nissan unveils prototype production facility for solid-state batteries
Nissan has unveiled a prototype production facility for laminated all-solid-state battery cells, which the company aims to bring to market in 2028. This prototype facility, within the Nissan Research Center in Kanagawa Prefecture, is designed to promote the development of solid-state-batteries. Nissan plans to establish a pilot production line at its Yokohama Plant in 2024,… Read more »
Are solid-state batteries always safer than Li-ion?
Many in the EV industry see solid-state batteries as the future, and one of the reasons is that the more stable solid electrolyte is expected to be safer than current liquid electrolytes. However, new research indicates that the picture may be more complex. A recent study led by the DOE’s Sandia National Laboratories, published in… Read more »
Mercedes-Benz teams up with ProLogium on solid-state batteries
Mercedes-Benz and battery firm ProLogium are teaming up to develop solid-state batteries. The automaker will make an unspecified investment in ProLogium, and will take a seat on the company’s board of directors. The first test vehicles using the new batteries are not expected to appear for several years. “We believe that range and efficiency are… Read more »
