from chemistry to pack
2026 OEM Claims vs. Actual Dates Every major automaker and cell maker working on solid-state batteries has, at some point, put a year on when a real customer will be able to buy a car with one inside. Those years keep moving. This post lines up the current public claims from five of the most … Read more
Every solid-state chemistry roundup mentions that cells need “stack pressure,” usually as a single line in a spec table. What that line means for the person actually designing the pack around the cell: This gets skipped almost everywhere. This is the pack-design follow-on to our cell-level piece on What’s the right stack pressure?, which covers … Read more
Author Dr. Simon Madgwick of Nuvvon Inc. Nuvvon recently showed their solid state 5Ah SiC NMC cell cycling continuously at 3C/5C for 1000 cycles full DOD to 90% SOC. Then incredible sub-zero temperature performance discharging down to -50°C with over 50% capacity and charging at -40°C. Here is the final post on these 5Ah Silicon cells – comparing … Read more
Author Dr. Simon Madgwick of Nuvvon Inc. Last post Nuvvon showed their solid state 5Ah SiC NMC cell cycling continuously at 3C/5C for 1000 cycles full DoD to 90% SoC. Next up is the cell demonstrating incredible sub-zero temperature performance. Here we see discharging at C/5 down to -50° C delivering over 50% capacity. Such cold temperature performance is … Read more
Nuvvon pushes True Solid State boundaries … again Author Dr. Simon Madgwick of Nuvvon Inc. Recently Nuvvon shared 1Ah pouch cell specs for Gr-NMC811 and Li-NMC9 plus the related safety test data (nail and ARC). Here is complete cycle data for the Gr-NMC811 cells (it takes a while to get 900 cycles … and counting) and the … Read more
Number 2 in the article 10 things about SSBs that you are often not told is 2. Pressure – a commonly hidden problem. The image of the battery pack itself was not included in the original press article, but it is available within the images released to the press. The battery pack/module is very uniform … Read more
Among the two broad classes of solid electrolytes, inorganic ceramics currently offer the highest room-temperature conductivities (10⁻³–10⁻² S cm⁻¹) but demand high-temperature sintering, are mechanically brittle, and suffer from large interfacial impedance with composite electrode [1]. Solid polymer electrolytes (SPEs), such as polyethylene oxide (PEO)–LiTFSI, polycarbonates, and block-copolymer systems, trade some conductivity (10⁻⁵–10⁻³ S cm⁻¹ … Read more
Author Dr. Simon Madgwick of Nuvvon Inc. Nuvvon Solid State Passes Nail Test with Graphite-NMC811 and Lithium-NMC9 Nuvvon has been building solid state cells for years and has long since exposed the things SSB players don’t tell you. There are some 60 so called Solid-State offerings out there but none with a completely dry cell that operates … Read more
Author Dr. Simon Madgwick of Nuvvon Inc. In the post about 10-things (10 things about SSBs that you are often not told) Nuvvon highlighted key issues including safety, pressure, lithium compatibility and scalability. At that time Nuvvon were making small cells around the 100mAh range with modest cycle life & C rate but nonetheless truly solid … Read more
Author: rhd instruments GmbH & Co. KG Introduction As the solid-state battery field matures and more attention is turned to detailed characterization of interfaces and individual redox processes, the need for a suitable reference electrode (RE) system emerges, in order to enable three-electrode measurements [1, 2, 3]. While the use of standardized REs is well-established … Read more
