SIGRATHERM® solutions for battery thermal management
SIGRATHERM graphite foils enable uniform temperature distribution and efficient heat dissipation - even in the event of thermal runaway. This means that they can contribute to a reliable and
Chip heat dissipation. In computer CPU, GPU and other chip heat dissipation module, graphite thermal sheet can quickly spread the heat generated by the chip. Ensure the stable operation of the chip within the safe temperature range, improve the performance and service life of electronic equipment; Mobile phone heat dissipation.
Author to whom correspondence should be addressed. This study investigates a hybrid-battery thermal management system (BTMS) integrating air-cooling, a cold plate, and porous materials to optimize heat dissipation in a 20-cell battery pack during charging and discharging cycles of up to 5C.
The results reveal that, among the examined materials, graphite is the most effective in maintaining the battery temperature within an acceptable range, particularly during high C-rate charging. Graphite integration significantly reduces the thermal stabilization time from over an hour to approximately 600 s.
The battery temperature exceeds the permissible range significantly when charging for 3C and 5C batteries. On the other hand, if graphite fills the gap between the batteries, the battery temperature remains below 318 K, demonstrating graphite's effectiveness in regulating the battery pack temperature when charging at a rate of 5C.
