Can liquid-cooled battery thermal management systems be used in future lithium-ion batteries?

Based on our comprehensive review, we have outlined the prospective applications of optimized liquid-cooled Battery Thermal Management Systems (BTMS) in future lithium-ion batteries. This encompasses advancements in cooling liquid selection, system design, and integration of novel materials and technologies.

What is liquid cooling in lithium ion battery?

With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.

What is a battery energy storage system?

Businesses also install battery energy storage systems for backup power and more economical operation. These “behind-the-meter” (BTM) systems facilitate energy time-shift arbitrage, in conjunction with solar and wind, to manage and profit from fluctuations in the pricing of grid electricity.

Are lithium-ion batteries a viable option for energy storage systems?

However, Lithium-Ion batteries remain the predominant choice for energy storage systems. This is primarily due to their decreasing costs, improved performance, lightweight design, and space-efficient nature, resulting in higher energy density than other battery types. Nevertheless, alternative battery technologies are emerging as viable options.

How to improve the cooling performance of a battery system?

It was found that the cooling performance of the system increased with the increase of contact surface angle and inlet liquid flow rate. For the preheating study of the battery system at subzero temperature, they found that a larger gradient angle increment was beneficial to improve the temperature uniformity.

Which electric vehicles use liquid cooling?

For example, the Tesla Model S electric vehicle uses indirect liquid cooling, and the coolant is a mixture of water and ethylene glycol . The Chevrolet Volt and BMW i3 and i8 also use liquid cooling systems for battery thermal management to avoid excessive battery temperature .
