how to charge a li-ion battery with a small amperage?
$begingroup$ A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V.

Why is there no current flowing across the battery
When R is very large, I will be very small. Once you get to R=100 ohms, then 100*0.02=2V, so that the 0.02 A when flowing through the resistor R will exactly produce the 2V drop and thus require no current through the 2V battery. If R goes below 100 ohms, then you will again see current flowing through the 2V battery, but in the other direction.

Current flow in batteries?
The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow. In your battery example, there is no return current path so no current will flow.

6 Frequently Asked Questions about “Will the battery compress a very small current ”
How much current can a battery supply?
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
What determines the amount of current a battery can supply?
The amount of current a battery can supply is determined by several factors. The first factor is the battery's voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
Do batteries need a lot of current?
If you only need the battery for a short period of time, it won't need to supply as much current as if you were going to be using it for an extended period of time. Finally, you need to consider the temperature. Batteries perform better in cooler temperatures and can supply more current in those conditions.
Can a current flow in a battery?
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
What happens if a battery is fully charged?
The charging current of the battery will decrease, and the battery charging current will decrease as it approaches full capacity until the battery is fully charged. Another is that there is no harm in charging a fully charged battery because the current will be very small.
How does voltage affect a battery?
The higher the voltage, the more current the battery can supply. The second factor is the battery's capacity. This is measured in amp-hours (Ah), and it refers to how much charge the battery can store. The higher the capacity, the more current the battery can supply. The third factor is resistance.
