When water-based direct cooling was applied to the battery at a coolant flow rate of 90 mL/min, the maximum temperature of the battery was reduced by 16.8 %, 20.2 %, and 23.8 %, respectively, which highlights the effectiveness of the proposed cooling system in controlling the battery temperature.
Herein, we develop a novel water-based direct contact cooling (WDC) system for the thermal management of prismatic lithium-ion batteries. This system employs battery surface insulation coatings instead of dielectric fluids to apply water-based coolants.
The system could preheat the battery at low ambient temperatures. Also, the numerical results indicated that the proposed contact cooling system exhibited outstanding temperature control capability and significantly reduced the pressure drop. The maximum temperature was decreased by 20.88 %, and the pressure drop was reduced by 79.78 %.
“We use materials such as magnesium and zinc that are abundant in nature, inexpensive and less toxic than alternatives used in other kinds of batteries, which helps to lower manufacturing costs and reduces risks to human health and the environment.” Distinguished Professor Tianyi Ma adds water as an electrolyte to a small battery.
“We recently made a magnesium-ion water battery that has an energy density of 75 watt-hours per kilogram (Wh kg-1) – up to 30% that of the latest Tesla car batteries.” This research is published in Small Structures. “The next step is to increase the energy density of our water batteries by developing new nano materials as the electrode materials.”
Therefore, researchers have proposed various battery thermal management systems (BTMSs), essential in managing the peak temperature and improving temperature consistency, enabling the battery to operate safely in an optimal operating environment.
Limitations of current approaches. The industry has widely adopted liquid cooling as the primary BESS thermal management technology. While this is a step up from traditional air cooling, when it comes to fully mitigating fire risks and effectively managing thermal events in high-density BESS setups, liquid cooling has its limitations, according to Jack Wu.
