What does it mean when a battery still has high voltage but
The internal resistance of the battery is high? That would explain why the voltage is high when there is no current but why there is no voltage when there is current. The more current is drawn by the battery, the more voltage is dropped across the internal resistance and therefore the less voltage actually appears on the battery terminals.

Charging Lithium Batteries: The Basics
Lead Acid Charging. When charging a lead – acid battery, the three main stages are bulk, absorption, and float. Occasionally, there are equalization and maintenance stages for lead – acid batteries as well. This differs significantly from charging lithium batteries and their constant current stage and constant voltage stage. In the constant current stage, it will keep it

What happens if a lithium battery expands during circulation?
Case 3: Lithium battery expands during circulation. As the battery circulates, the thickness increases as the number of cycles increases. However, after more than 50 weeks, it will not increase any more. Generally, the normal increase is 0.3 to 0.6 mm. Solution: This is a normal battery reaction.
What determines the maximum current a battery can supply?
It only determines how long the battery can supply a current for (that is, how much energy is can output over a period of time). The max current is determined by it's internal resistance.
