Hello, I own around 30 kinds of Huawei, Samsung, Dell, Apple pouch cells produced from 2016 to 2020. The cells are stored at low SOC in cold (max 12 deg C) which results in a minimal calendar aging. I am tracking the progression of Energy to weight gain, average voltage and maximum voltage in batteries with modified silicon-graphite anodes. Recent NEW cells (mainly produced by SONY MURATA, CATL/ATL, Lishen) have huge energy density, in practice at discharge current C/5 --- C/10 it exceeds 310 Wh/kg. HB526489EEW series - 5Ah, 67 grams (reports almost always 5.3Ah 21Wh).
If someone wants to buy cheaply any model in Poland I invite you to the Allegro portal. The seller is wesmag_pl. At ebay you can also find them, a bit more expensive due to international shipping:
