A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
Avoid using lead-acid battery chargers, as they have different voltage levels. Frequent Charging: To extend the life of lithium-ion batteries, they should be charged before reaching a low state of charge, ideally when they're at around 80% capacity. Avoid allowing them to fully discharge before recharging.
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process.
Frequent Charging: To extend the life of lithium-ion batteries, they should be charged before reaching a low state of charge, ideally when they're at around 80% capacity. Avoid allowing them to fully discharge before recharging. Proper Storage: When not in use, lithium-ion batteries should not be left in a discharged state.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.

Is charging 18650 lithium ion cells with lower current better?
The only way a low charging current might contribute to a reduced life is in the hands of an inexperienced designer who thinks that lithium cells behave like nickel or lead, and that if the current is low enough, then a gentle overcharge is permissible. With lithiums, no overcharge is ever permissible, see the second paragraph.

Lithium battery charging-undervoltage
Yes, charging a Li-Ion cell at constant voltage without ever terminating the charge will likely destroy the cell. What will happen is that your battery will get (maybe slowly) to 4.0 V, and, if the voltage stays, the charging current will gradually decrease, and will decrease to zero. This will put the cell into overcharged state, even if the ...
