Abstract
A phase change material (PCM) is positioned about a battery of an eyewear device such that a latent energy of the PCM transfers to the battery as the ambient temperature drops to maintain a battery temperature. The latent energy maintains the temperature of the battery until the PCM loses it latent energy and converts to a solid phase. At normal operating temperatures, the PCM is in the liquid phase.
