1. A barrier structure comprising:
a plurality of first sidewalls oriented in a first direction to interlock with a plurality of second sidewalls oriented in a second direction substantially perpendicular to the first direction to form a grid structure comprising a plurality of cells,
wherein:
one or more of the plurality of cells has an open-ended top and an open-ended bottom;
one or more of the plurality of cells is configured to be arranged around at least one of a plurality of batteries;
each of the plurality of first sidewalls and the plurality of second sidewalls comprises a serpentine shape having alternating arcs along a longitudinal direction of each sidewall; and
the plurality of second sidewalls are arranged such that the serpentine shapes of adjacent ones of the plurality of second sidewalls are out of phase with each other.
