All lithium-ion cells will continue increasing in voltage until the charge current is cut. So unless you have a damaged cell, the cell''s voltage will pass 4.2 and can go as high as 4.5 or 4.6 V. So it is possible that with an ideal CV supply, to keep it at 4.2 V, and let the cell naturally cut off the current as its voltage rises.
The high-voltage battery means that the battery has more voltage as compared to normal batteries. The present LiPo batteries can be classified into high voltage batteries (4.35 V / 4.4 V) and regular voltage batteries (4.2 V). The nominal voltage of a typical voltage battery is 3.6 V / 3.7 V, and the upper boundary of the charging voltage is usually 4.2 V.

Li-ion batteries should be stored in a charged state, maintain a voltage above 2.5V before they start to break down and decompose. According to the Li-ion batteries'' chemical features, as permanent capacity loss is greatest at elevated temperatures with the batteries voltage maintained at 4.2 V (fully charged), you also couldn''t maintain them at fully charged 4.2V.
When ever the battery voltage is above 4 volts the voltage fed back to the inverting input will be higher than 3.5 voltas. That is 4V-D1 drop =3.5V. The output of the opamp swings to ground and transistor Q1 will be switched OFF. This isolates the battery from the charging voltage and the battery remains safe.
