My Response to Donut Lab's Statement That All NMC Lithium Cells Will Overheat Charging at 11C

This is in response to Donut Lab's CEO Marko Lehtimaki's statement: "First of all, not a single NMC cell would perform like that during full 11C charge without active cooling and reaching 89 celsius. Happy to cover all the test costs and a little bonus to anyone who successfully does it with VTT or other trustworthy research lab and proves otherwise." So here's a 6 Ah NMC lithium cell heating up less than a one degree Celcius charging from empty to 80% SoC at 11C. My test mostly replicates the test shown in VTT's test report. Given that my cell heated from 23 degC to 24 degC, whereas Donut's cell heated from 23 degC to 89 degC; I propose any differences between the test setups are irrelevant. In other words, I am confident that an NMC cell will meet Marko's stated claims even after modifying the test to Donut's satisfaction. Marko, I accept your offer². Please get in touch so we can replicate my test results in the lab of your choosing. Or you can just do it yourself... I used a Sunwoda SHP-02-0060 NMC lithium cell. ²Please donate any prize money to the non-profit Truth In Advertising. ... Cell post-test performance results: https://github.com/doppelhub/Long-Ter...
