High-temperature batteries are rechargeable batteries designed to withstand extreme temperatures. They are typically made of Li-ion or Ni-MH cells capable of delivering high levels of power and energy density. Generally, high-temperature batteries can be divided into five levels: 100°C, 125°C, 150°C, 175°C, and 200°C and above.

Battery cooling methods fall under two general categories: passive cooling and active cooling. Passive cooling methods use natural heat dissipation like radiation and conduction to extract heat from the battery. This can include materials with high thermal conductivity.
PCM based cooling mechanisms utilize the large latent heat capacities of materials undergoing phase transitions between solid and liquid states to conduct heat away from the battery packs which demonstrates potential in enhancing thermal regulation.

For optimum power output and longevity, the lithium-ion traction battery used in an electric vehicle (EV) must be maintained between 15 °C (59 °F) and 35 °C (95 °F). At low temperatures, the electrochemical reactions necessary to produce electricity are sluggish, limiting the amount of power available.
However, the thermal safety and cycle life of LIBs are greatly affected by the operating temperature [3].Both high and low operating temperatures can increase the degradation of the battery and shorten its lifespan [4].Therefore, for EVs and HEVs, a battery thermal management system (BTMS) is utilized to maintain batteries in the optimal temperature range

The proposed cooling improves the temperature uniformity of the battery up to 57% and reduces the temperature rise of the battery to 14.8% with a rise in coolant flow rate from 652 mL/min to 1086 mL/min .
While battery cooling remains essential to prevent overheating, heating elements are also employed to elevate the temperature of the battery in frigid conditions. This proactive heating approach assists in mitigating the adverse temperature effects on the electrochemical reactions, ensuring the battery can still deliver power effectively.
