Can output of SPV1040 DIrectly be connected to Lion battery?

Hi, I could not find reference that the SPV1040 can be used directly as a CC CV LiON battery charger. Although in the circuit, you have directly connected it to the battery. Should we not hook up SPV1040 with a CC CV LiOn charger IC?

Another point is that R1 and R2 would make the output be 3.7V which is not the max voltage the battery can be charged upto. Is it a conscious decision or am I missing something?

Closing the issue. The value of R1 and R2 leads to a constant voltage of 4.2 volts which is ideal to charge the LiOn battery. was my calculation mistake.
