  • Patent number: 10916816
    Abstract: A low temperature (e.g., lower than 0° C.) or a high temperature (e.g., higher than 50° C.) can degrade battery performance, especially within lithium ion (Li-ion) batteries, and even accelerate the capacity fading. To ensure a long term and safe operation of Li-ion batteries, the battery thermal management (BTM) system becomes a crucial part to control the temperature of each discrete battery or every battery within a battery pack. Within the prior art a phase change material (PCM) has been employed combined with a graphite matrix. However, the graphite lowers the latent heat of entire BTM system and increases the manufacturing cost. Embodiments of the invention provide sealed mandrels or elements which immobilize the PCM without impacting the latent heat of the entire BTM system and increasing manufacturing costs.
