When water infiltrates a lithium battery, it sets off a series of harmful reactions, potentially leading to heat generation, hydrogen release, and potential fire hazards.
In 2018, the batteries of a LIFAN 650 EV caught fire during operation due to a short circuit after immersion in water . Thus, there are clear potential safety hazards associated with the immersion of LIBs in water; therefore, it is crucial to study the impact of immersion on LIBs.
In this work, the electrochemical performance, aging mechanisms, and thermal stability of batteries after immersion were experimental investigated. The conclusions can be summarized as follows: Battery corrosion increases with increasing electric potential, salt concentration and immersion time due to the electrolytic reaction.
This happens when water allows the current to bypass the intended circuit, leading to uncontrolled discharge, overheating, or even battery failure. Thermal Runaway: If a lithium-ion battery short-circuits in water, it can cause thermal runaway—a condition where the battery generates excessive heat.
Fire Hazard Lithium-ion batteries are highly susceptible to catching fire when submerged in water. The water can cause the battery to short circuit, and as the battery heats up, it may ignite. Even worse, water cannot extinguish a lithium battery fire. Instead, it can exacerbate the flames, making the situation far more dangerous.
The interaction between lithium-ion batteries and water can lead to dangerous reactions, including short circuits, chemical fires, and even explosions. This article explores why submerging lithium-ion batteries in water is hazardous and what precautions should be taken to prevent potential disasters.
However, when submerged in water, especially saltwater, several issues arise: Short Circuits: Water can easily breach the protective casing of the battery and cause a short circuit. This happens when water allows the current to bypass the intended circuit, leading to uncontrolled discharge, overheating, or even battery failure.
Battery energy storage system (BESSs) is becoming increasingly important to buffer the intermittent energy supply and storage needs, especially in the weather where renewable sources cannot meet these demands. However, the adoption of lithium-ion batteries (LIBs), which serve as the key power source for BESSs, remains to be impeded by.
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.
Developing energy storage system based on lithium-ion batteries has become a promising route to mitigate the intermittency of renewable energies and improve their utilization efficiency. In this context, thermal management is needed to maintain battery temperature and thermal uniformity without consuming significant power.
Therefore, the current lithium-ion battery thermal management technology that combines multiple cooling systems is the main development direction. Suitable cooling methods can be selected and combined based on the advantages and disadvantages of different cooling technologies to meet the thermal management needs of different users. 1. Introduction
Computational fluid dynamic analyses were carried out to investigate the performance of a liquid cooling system for a battery pack. The numerical simulations showed promising results and the design of the battery pack thermal management system was sufficient to ensure that the cells operated within their temperature limits.
Lithium-ion batteries can operate over a wide range of temperatures, but the range is much narrower to ensure their power output. 10 The battery thermal management system is one of the important ways to keep the battery working at a proper temperature.
The study reviewed the heat sources and pointed out that most of the heat in the battery was generated from electrodes; hence, for the lithium-ion batteries to be thermally efficient, electrodes should be modified to ensure high overall ionic and electrical conductivity.
Choosing the right thermal management system for the batteries of electric vehicles is crucial to address electrical energy used by electric ancillary. We have rated every system from 0 to 5 according to 4 criterias: 1. Cooling 2. Heating 3. Fast charging 4. Safety (prevent thermal runaway.
Immersed liquid-cooled battery system that provides higher cooling efficiency and simplifies battery manufacturing compared to conventional liquid cooling methods. The system involves enclosing multiple battery cells in a sealed box and immersing them directly in a cooling medium.
The battery pack heating is also provided by the coolant, while heat sources and heating strategies can widely vary from application (e.g. waste heat recovery from other powertrain systems or direct heating of the battery coolant through PTC heater for example). Coolant cooling is an efficient system for several reasons:
It is the simplest approach to battery cooling. Using conduction through battery and vehicle mounts, as well as natural convection within the battery pack, it transfers the heat generated inside the pack to the environment with no, or limited (e.g. ducting), additional hardware.
A liquid or air cooling system must manage this elevated heat without compromising safety or performance. Fast charging also demands cooling systems capable of rapidly dissipating generated heat to prevent overheating, a factor that could undermine battery longevity and safety.
Xiaoyu Na et al. [61, 62] developed a simplified calculation model for reverse-ventilated battery pack cooling and shown that this technique efficiently reduces the maximum interior battery pack temperature while also reducing the local range of temperatures. However, air cooling cannot effectively manage the temperature in hot weather.

Effective battery cooling measures heat dissipation to prevent overheating, safeguarding the charging rate and the battery from potential overheating issues.
Based on the position of the liquid cooling system, it can be divided into internal and external cooling. Internal cooling can cool battery from the heat source by incorporating the cooling system into the battery. This cooling strategy is very efficient that can reduce the heat resistance between the heat source and the coolant.
Battery cooling is part of the vehicle's Battery Thermal Management System (BTMS). The BTMS includes the cooling and heating module, as well as the operating strategy, control system and thermal management software.
This heat is carried from the batteries to the bottom surface of the pack and dissipated by the coolant. Thermal pads are used to remove air gaps from the contacting zone, thereby reducing thermal resistance. Batteries have not been modeled. In place of that, a constant heat flux was applied to the contact area of the cooling plate.
Through the numerical analysis, comparison was carried out to find out the performance of the proposed internal cooling scheme with external cooling scheme. The internal cooling scheme can not only reduce the maximum internal temperature of the battery, but also improve the temperature uniformity between the batteries.
While battery cooling remains essential to prevent overheating, heating elements are also employed to elevate the temperature of the battery in frigid conditions. This proactive heating approach assists in mitigating the adverse temperature effects on the electrochemical reactions, ensuring the battery can still deliver power effectively.
In addition to the choice of fluid, the above concepts also differ in how the cooling plates are attached. A cooling plate can be attached to the battery from above or below in a horizontal position; if high cooling capacity is required, two cooling plates can be used as a sandwich.
Liquid cooling, as the most widespread cooling technology applied to BTMS, utilizes the characteristics of a large liquid heat transfer coefficient to transfer away the thermal generated during the working of the battery, keeping its work temperature at the limit and ensuring good temperature homogeneity of the battery/battery pack.

Abstract: Battery thermal management is becoming more and more important with the rapid development of new energy vehicles. This paper presents a novel cooling structure for cylindrical power batteries, which cools the battery with heat pipes and uses liquid cooling to dissipate heat from the heat pipes.
The system involves submerging the batteries in a non-conductive liquid, circulating the liquid to extract heat, and using an external heat exchanger to further dissipate it. This provides a closed loop immersion cooling system for the batteries. The liquid submergence and circulation prevents direct air cooling that can be less effective.
By changing the surface of cold plate system layout and the direction of the main heat dissipation coefficient of thermal conductivity optimization to more than 6 W/ (M K), Huang improved the cooling effect of the battery cooling system.
