Are lithium-ion batteries safe for energy storage systems?

Lithium-ion batteries are increasingly employed for energy storage systems, yet their applications still face thermal instability and safety issues. This study aims to develop an efficient liquid-based thermal management system that optimizes heat transfer and minimizes system consumption under different operating conditions.

How to dissipate the heat of battery pack?

Zhou et al. combined the heat pipe with the LIC system to dissipate the heat of battery pack by using Novec 649 with good dielectric properties. Study showed that the peak module temperature and the peak temperature difference were limited to below 47℃ and 2.1℃, respectively.

Are battery energy storage systems a viable solution?

However, the intermittent nature of these energy sources also poses a challenge to maintain the reliable operation of electricity grid . In this context, battery energy storage system (BESSs) provide a viable approach to balance energy supply and storage, especially in climatic conditions where renewable energies fall short .

Why are battery surfaces immersed in liquid?

All the battery surfaces were immersed in the liquid, which can provide a uniform, high-capacity heat transfer path for battery cooling.

How does heat dissipation affect a battery pack?

As a result, the disturbance in the upper portion of the battery pack was more intense, i.e., it corresponds to a stronger heat dissipation flux, which further reduces the heat accumulation at the upper portion of the battery pack. Fig. 16.

How does a battery pack work?

In the first type (Case 1), the bottom side of battery pack is contact with a baffled cold plate, where baffles are inserted in the flow channel to distribute an even volume rate across four battery modules. After optimization, the spacing between baffles are set to 22 mm and the height of channel is 7 mm.
