Yes. Still few people understand about li-ion. The main thing to understand is there is so many different ways to make them it is quite impossible to know enough to make any general assumptions. There’s maybe less than dozen people in the world who can say anything in general. I can only say I know those cells I am making and which I have been litterallyt living with almost two decades. It is not about knowing all but to know what one specific cell type can do. And when certain treshold of knowledge is met most things around it can be optimized to get the job done (what ever it is). -Jukka
