Most EVs with LiIon batteries have less than 4.2V maximum charge voltage and recommend charging up to 80-90% of available capacity when possible. (Source: my ID.4 owners manual) I also know that charging a lithium ion battery involves a constant current and constant voltage phase. It usually does, but it's not necessary.
The common sense of lipo voltage as below: 1. A fully charged lipo voltage is 4.2V per cell (HV lipo can be charged to 4.35V). 2. A lipo cell battery should never be discharged below 3.0V. 3. The proper lipo storage voltage is 3.8V per cell. 4. A lipo cell nominal voltage is 3.7V.
Yes, an 18650 3.7V lithium-ion battery can use a 4.2V charger because 4.2 volts is the standard charging voltage for most lithium-ion batteries when they are fully charged. The nominal voltage of these batteries, which is typically listed as 3.7V, refers to their average or operating voltage during use, not the charging voltage.
I recently came across a device (a headlamp) with lithium-polymer battery, which is marked 3.8 V nominal voltage, instead of usual 3.6-3.7 V. It's charging circuit is based on ME4057D chip, which is a 1 A lithium battery charger.
I wouldn't care about bottom limit much. The cutoff voltage is 4.4 V. It's a high voltage lithium polymer accumulator. You can hook it up to a standard charging circuit (that means 4.2 V cutoff I assume) but you won't get the claimed capacity out of it. But you will drastically increase the cycle count of the battery, so that's a plus.
If the cell temperature reaches 175°C with a cell voltage of 4.3 V, thermal runaway may occur and the battery may explode. Similarly, Figure 3 shows the JEITA guidelines for charging Li-ion batteries in single-cell handheld applications, where the charge current and charge voltage are also functions of the cell temperature.

The battery performance is the most stable in the platform period, while the performance of the battery pack will be unstable in the low SOC or overcharge state. The lithium battery will not be charged after it is fully charged, and the power output will be stopped when the SOC = 30%, which can make the service life of the lithium battery longer.

Aircraft - General Batteries and Chargers Li-Poly--why charge to 4.25V per cell?
How to solve the problem of Polymer Lithium Battery puffy? (1) Lithium Battery Manufacturers must strictly control the production process. (2) During charging the battery, the user should avoid overcharging and protect the battery from harm. (3) Users must stop using the lithium battery after they find that the battery is swelling.
The battery industry raised the voltage a few years back from a maximum of 4.2 V to the present-day value of 4.35 V. This was responsible for adding approximately 4 to 5% to the energy density.
