Is instantaneous maximum possible peak current a common datasheet specification?

Instantaneous maximum possible peak current isn't a common datasheet specification for a battery. So you are asking if, by some tremendous luck, someone has spent time characterizing the exact battery you have in hand under those circumstances and would be willing to share?

Why do Lib batteries need to be charged?

The discharge performance of LIBs has different requirements than charging, as the battery needs to satisfy required discharge power, for example, to support speeding or climbing in EVs and playing games or using power hungry apps on mobile electronics. Often times there is need for short bursts of large power or pulse power to support the load.
