Hi
As long as I remember about battery charging technology I knew that CC/CV is the safest charging technique for charging Li-ion batteries. Now I suddenly read about this. https://qnovo.com/why-is-charging-with-cccv-bad/
A company named qnovo who built some technology for big guys like Sony, Intel, Qualcomm etc claiming that cccv actually bad and damages the battery and its capacity, cycle life etc.
Are their claims true or false?
Then what other charging methods we can use to charge our packs?
Please tell us your views.
Also, the guys in battery University claim that CC/CV is the only method for charging Li-ion cells. http://batteryuniversity.com/learn/article/what_everyone_should_know_about_battery_chargers
About CC/CV method if I'm not wrong (if yes correct me please) first constant current applies to empty cells with lower voltage, then, when it's full about 80% current drops and voltage rises to 4.2v and cuts off, right? Then whats the traffic collision of ions inside batteries they are claiming is all about?

Of all chargers, the Li-ion charger is the most simplistic. No trickery applies to improve battery performance and longevity. Only the CCCV method works.
