1. A battery system comprising:
- a housing at least partially enclosing an internal volume, said housing being made of a heat-resistant material and including at least one vent that fluidly couples said internal volume with an atmosphere surrounding said housing;
at least one containment device located within said internal volume;
at least one battery cell module placed in said at least one containment device, said containment device being configured to retain electrolyte and debris released during a thermal runaway of said at least one battery cell module; and
a support structure within said internal volume, said support structure configured to support said at least one containment device in said internal volume.

20. A method for operating a battery system at a target voltage, the method comprising:
-
providing a housing defining an internal volume, said housing being made of a heat-resistant material and including a vent that fluidly couples said internal volume with an atmosphere surrounding said housing, said housing fully enclosing said internal volume but for said vent; placing a plurality of battery cell modules into a plurality of containment devices, said containment devices each being configured to retain electrolyte and debris released during a thermal runaway of one or more of said plurality of battery cell modules placed therein; providing a support structure within said internal volume, and supporting said plurality of containment devices on said support structure; applying a charging voltage to said plurality of battery cell modules; monitoring each battery cell module of said plurality to identify a malfunctioning battery cell module within said plurality; and when said malfunctioning battery cell module is identified, electrically isolating said malfunctioning battery cell module from said other battery cell modules of said plurality; and increasing said charging voltage applied to said other battery cell modules of said plurality.
