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 »
DOE issues $16-million lab call to strengthen domestic manufacture of solid-state and flow batteries
A new lab call promotes collaboration between DOE National Laboratories and industry partners to accelerate the development, from innovation to scale-up and commercialization, of the manufacture of two types of advanced batteries: solid-state and flow. Solid-state batteries are widely considered to be a safer alternative to current batteries that use liquid electrolytes. Flow batteries, which… Read more »
LiNa Energy demonstrates dynamic containment with its solid-state sodium batteries
LiNa Energy, a developer of solid-state sodium batteries, has successfully completed an independent demonstration of its batteries for energy storage systems. In the test, a 1 kW / 1 kWh LiNa system performed dynamic containment. This is a key revenue stream for battery energy storage systems in the UK, which requires rapid injection and absorption… 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 »
