Are lithium-ion blade batteries a good choice for energy storage systems?

For today’s new energy vehicles, lithium-ion blade batteries are an ideal choice for modern energy storage systems due to their high energy density and safety. For effective thermal management strategies, this paper mainly focuses on two heat dissipation modes: air cooling and liquid cooling.

Can direct cooling improve battery thermal management?

Provided by the Springer Nature SharedIt content-sharing initiative Direct cooling technology is regarded as a promising method for battery thermal management owing to its high heat transfer efficiency. However, the overhea

Can a blade battery be locally heated?

We found that the application of both technologies is essential to improve the performance and extend the life of the battery, and the CFD simulation of the two methods under the same environmental conditions shows that the blade battery will also be locally heated when it is dissipated by air cooling.

Can a half helical duct cool a cylindrical battery?

A direct cooling system based on helical-flow ducts is a promising method for cooling cylindrical batteries. In this study, the performance of a half-helical duct utilizing refrigerant R134a for the direct cooling of an 18650-type battery via flow-boiling heat transfer was numerically analyzed.

Can helical-flow ducts cool cylindrical batteries?

The miniaturization of the cooling unit improves temperature uniformity and reduces the temperature gradient along the battery axis. A direct cooling system based on helical-flow ducts is a promising method for cooling cylindrical batteries.

How to control battery temperature uniformity?

To improve the control of battery pack temperature uniformity, Xu et al. designed a wrench-shaped cold plate with a hierarchical channel and a wavy surface to match the geometric form of cylindrical batteries, differing from traditional rectangular designs.
