from chemistry 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
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
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
CATL’s automotive-grade NMC811 prismatic cell ships with a headline safety feature: a “Dual Vent Safety Design.” The specifications: We believe this cell is for ACC. Jerry Wan shared details of this CATL cell on LinkedIn and it got us thinking: Why vent design matters more on NMC811 A cell’s vent only has one job: get … 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
Author Dr. Simon Madgwick of Nuvvon Inc. Since the Nuvvon post unveiling Solid State Silicon Anodes (1Ah Silicon NMC), the cells have been scaled up and further differentiated into 250Wh/kg Power cells versus 400Wh/kg Energy cells. Here is the Power cell with continuous 3C Charge / 5C Discharge full DOD – at point of posting 1014 cycles … Read more
This is from a poster and shows the Gotion Universal Cell MEB+ battery pack. We have already looked at the 2026 VW Polo MEB+ LFP pack that delivers 37kWh using the universal cell format. This pack has a total energy = 65.59 kWh and using the Usable SOC window of the smaller pack of 96% … Read more
We have just received the specification sheet for the JLi Battery Co 37Ah 4695 cell and it is really interesting. This is a 335Wh/kg cylindrical cell with a Ni-rich NMC cathode + Silicone Carbon anode. The cells are using aluminium shell to enable the lightest weight and highest thermal performance. The Welding instructions for this … Read more
We have initial data for the 2026 BYD Short Blade 2.0 cell based on a shared [1] teardown of a 75.6kWh pack. Specifications Charge Rate – supports a massive 8C peak charge rate. Under optimal conditions with the right charger, this rate allows the short blade battery to charge from 0% to 80% (and potentially … Read more
