An article comprising:
- a battery pack comprised of a plurality of battery cells;
- a housing external of the battery pack and covering at least a portion of the battery pack;
- and
- a silicate-based thermal barrier coating configured to block heat emitted from the battery pack, the silicate-based thermal barrier coating including, by total weight of the silicate-based thermal barrier coating, 35-45% of sodium silicate, 1-2% of thermal barrier particles, and 0.09-0.15% of non-ionic surfactant.
