from chemistry to pack
The MG4 Anxin Edition is being sold as the first mass-market car with a semi-solid-state pack. This is a pack analysis rather than a teardown report: a Chinese teardown channel has photographed the pack nameplate, a regulatory filing gives the pack mass, and the cell maker has shown a slide with the cell and string … Read more
Pack analysis of the production Mercedes CLA: 58 kWh LFP, 71 kWh and 85 kWh NMC packs from CATL, 192 cells at 800V, charging curve, and comparison with Tesla Model 3 and BMW Neue Klasse.
A review of Fischer et al. (2026): three 5 to 6 year old Hyundai Kona Electric packs measured intact and then component by component, showing how capacity and ohmic resistance scale from cell to pack.
BYD’s Blade Battery 2.0, introduced in March 2026, represents a significant leap over the first-generation Blade Battery 1.0 launched in 2020. While the first generation revolutionized battery safety and packaging efficiency, the second generation introduces sweeping material overhauls to dramatically improve charging speed, energy density, and cold-weather performance. However, the Blade 1.0 design improved throughout … Read more
Grid storage cells have grown quickly. The 280Ah and 314Ah LFP prismatic cells that defined the early 2020s are being displaced by 500Ah-plus formats, with 587Ah, 628Ah and 684Ah in production or launch, and claims above 1000Ah announced [1]. The interesting engineering question is where the benefit actually lands. Most of it shows up at … Read more
Lithium manganese-rich (LMR) cathodes are back in the conversation because a major automaker has put dates on them. General Motors and LG Energy Solution have said they will build prismatic LMR cells at Ultium Cells, with pre-production at an LG facility by late 2027 and commercial production in the US in 2028 [1]. This post … Read more
How much energy will a cell hold in 2030, or in 2035? (If you need a refresher on the two measures, see cell energy density.) Most answers to that question start from a target or a press release. This one starts from the cells themselves. We took every cell in our cell database that has … Read more
CATL and Quibo’s Mobile Power Plant Ultra 2.0 packs up to 2,036 kWh, a converter, EV chargers and a solar inverter into a 20-foot container. What the IAA 2026 placard discloses, what it leaves out, and how it compares.
The Battery Data Behind IAA Transportation 2026 IAA Transportation 2026 ran in Hannover from 15 to 20 September, and electrification was the theme running through most of the exhibitor announcements: Volvo, DAF, MAN, Scania and SANY all had electric truck news on the stand. The one battery-specific launch worth digging into in detail is CATL’s … 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
