I think pretty much all Li-ion chemistries can be charged at constant
current to 80 percent, then at constant voltage. The last 20 percent
takes a long time. The charging is terminated when the current drops
below a certain limit in the constant voltage mode. This is mandatory:
they cannot be float charged like other types. I think all the Li-ion
charge controller chips do this.

I have Lithium batteries in my laptop, my KX2, my electric razor, a

chargers for each of them.
I think the dedicated, automatic chargers fill the batteries to 100%,
so there must not be a lot of caution to only charge them to 80%.
