Note that LFP//graphite chemistry (like any battery chemistry) can deliver much higher power ratings in cylindrical cells (refer to figure 40), but in large-scale pouch cells between 25–280 Ah, the manufacturers recommend a maximum continuous discharge from 1 to 3 C [293].PDF Image | 2021 roadmap for sodium-ion batteries
