Nissan to use solid-state batteries, gigacasting in its next-gen EVs
Nissan, Japan’s third-biggest automaker by volume, plans to begin producing solid-state batteries for EVs at scale by early 2029, and will also use Tesla-style gigacasting machines in order to increase efficiency and drive down costs on its future EV models. Solid-state batteries are expected to deliver faster charging and longer lifespans than current Li-ion designs…. Read more »
Samsung SDI announces plan to mass-produce solid-state batteries
EV battery manufacturing company Samsung SDI has announced a suite of battery technologies, including fast charging and ultra-long life batteries, as well as its roadmap for mass production of all-solid-state batteries (ASBs). Samsung SDI plans to mass-produce 900 Wh/L solid-state batteries using its solid electrolyte and anode-less technologies, the latter of which enables higher cathode… Read more »
Penn State team uses cold sintering to reprocess solid-state composite electrolytes
A team at Penn State has reported using cold sintering to reprocess solid-state composite electrolytes. According to research published in an open-access paper in the journal ChemSusChem, the technique was used to reprocess Mg- and Sr-doped Li7La3Zr2O12 with polypropylene carbonate (PPC) and lithium perchlorate (LLZO–PPC–LiClO4). The low sintering temperature allows co-sintering of ceramics, polymers, and… Read more »
ION Storage Systems achieves milestone with its anodeless solid-state battery
ION Storage Systems, a Maryland-based manufacturer of solid-state batteries, has announced that its anodeless and compressionless SSB achieved a key threshold with its first market deployment with the US military. ION says its SSB successfully exceeded 125 cycles with less than 5% capacity degradation in performance, offering the potential for more than 1,000 cycles in… Read more »
QuantumScape introduces a new cell format for solid-state EV batteries
QuantumScape, a US battery company, has introduced a new cell format, FlexFrame, for solid-state EV batteries. FlexFrame combines pouch and prismatic cells. The FlexFrame architecture has a frame that wraps around the cell stack and a flexible polymer laminate outer layer like pouch cells. The cell is anode-free and the cell stack is contracted, with… Read more »
Amperesand’s solid-state transformers could help break electric grid bottlenecks
Here’s a story we hear often: a CPO or fleet operator wants to deploy a large-scale EV charging facility, but the project is delayed for months or years because the local utility is waiting for the necessary transformers to be delivered. (Two out of two subjects of infrastructure articles in our current print issue—XCharge’s Alex… Read more »
Saint-Gobain invests in solid-state battery firm ION Storage Systems
NOVA, the partnership and venture capital branch of building materials company Saint-Gobain, has invested in solid-state lithium metal battery company ION Storage Systems to expand their battery technology collaboration. The companies are working to establish US manufacturing of ceramic material for large-scale solid-state battery electrolyte manufacturing. In September, ION announced a multi-year supply arrangement with… Read more »
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 »
Comau and LiNa develop automated manufacturing for solid-state sodium batteries
Comau, an Italian industrial automation company and LiNa, a solid-state sodium battery manufacturer, are developing a scalable manufacturing solution for sodium-metal-chloride battery cells. Comau provided LiNa with a detailed cell manufacturing automation roadmap. Comau and LiNa engineers designed the enclosure and handling equipment for solid-state battery cell components. They also identified and integrated commercially available… Read more »
