Presented are active thermal management (ATM) systems with multi-purpose reservoirs for liquid-immersion cooled battery assemblies, methods for making/using such systems, and motor vehicles equipped with such systems. An ATM system for a battery assembly includes a coolant reservoir that stows a liquid immersion cooling (LIC) fluid, and an inlet manifold that fluidly connects the reservoir to the battery assembly's battery case to transfer LIC fluid into an immersion compartment within the battery case. An outlet manifold fluidly connects the battery case to the reservoir to transfer fluid out from the immersion compartment. An auxiliary vent manifold selectively fluidly connects the battery case to the reservoir responsive to a predefined thermal event to thereby transfer LIC fluid and battery cell vent gases from the immersion compartment to the reservoir. A gas valve, which is fluidly connected to the reservoir, selectively evacuates therefrom the vent gases at a predefined internal reservoir pressure.
