1. A battery system, comprising:
an enclosed housing having an internal volume;
a battery cell provided in the internal volume, wherein the battery cell is configured to output thermal energy as a byproduct of electrical energy generation and/or consumption;
a wall of the enclosed housing with a first side positioned proximate to the battery cell; and
a plurality of fins extending from a second side of the wall external to the enclosed housing, the plurality of fins being arranged in a grid-like structure and configured to absorb thermal energy from the battery cell and dissipate the thermal energy to air, or a heat sink, or both, wherein a fin of the plurality of fins comprises a channel configured to facilitate a flow of the air between the fin of the plurality of fins and an adjacent fin of the plurality of fins.
