A review of Zhao, Leung and Huang (2026): using pre-calender measurements and process settings to predict post-calender thickness and early-cycle capacity in NMC811 cathodes, and what the results do and do not show.
Quantifying microstructure differences across Gr-SiOx anodes stopped at states of charge from 0 to 100%. Introduction Fast charging in graphite-silicon suboxide (Gr-SiOx) composite anodes depends on maintaining efficient ionic transport as the electrode evolves during lithiation. This is particularly challenging because the two active phases undergo different degrees of dimensional change. SiOx offers substantially higher … 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
Quick facts The prompt for this piece Prof Louis Piper (WMG/Warwick, Faraday Institution) posted a summary of this paper on LinkedIn, describing work from the Faraday Institution’s LEAP project led by Eleni Fiamegkou and Daniela Proprentner. His framing of the result is worth repeating directly, because it’s the thesis the underlying data set out to … Read more
A new Nature Energy paper puts a number on it I’ve written before about cell electrode pressure and how it’s applied and lost across a module’s life, and about the practical business of mapping pressure distribution across a pouch cell in operando. Both of those pieces stopped short of answering the question every pack designer … Read more
Author Dr. Simon Madgwick of Nuvvon Inc. In yet another breakthrough Nuvvon has used its Solid Polymer Electrolyte (SPE) to combine a high silicon anode with a high nickel cathode. See below data set for 1Ah 40% silicon graphite vs NMC 811. Crucially, the SPE is able to accommodate traditional expansion issues associated with high silicon, without … Read more
AION Engineering INC The performance of a lithium-ion cell is fundamentally governed by its material chemistry, particularly the composition of its cathode active material (CAM). In this article, we focus specifically on the role of nickel content in Nickel Manganese Cobalt Oxide (NMC) materials and how it correlates with energy density and power capability. Although … Read more
AION Engineering INC In lithium-ion battery technology, optimizing cell performance and safety requires careful consideration of multiple parameters. Among these, the cut-off voltage is critical for balancing energy density and ensuring cell longevity and stability. While cathode chemistry often guides cell classification, variations in anode materials significantly impact the appropriate cut-off voltage setting. Influence of … Read more
The Polestar 3 shares the Volvo SPA platform with Volvo EX90. Note: Lotus has its own derivative of the SEA platform called EPA. SEA and EPA has many similarities while SPA and SEA is quite different. Metrics This post has been built based on the support and sponsorship from: Thermo Fisher Scientific, Eatron Technologies, About:Energy and Quarto Technical Services. Specifications … Read more
