This review will be helpful for improving the thermal safety technology of high-energy density lithium power batteries and the industrialization process of low-temperature heating technology. 2. Effect of low temperature on the performance of power lithium battery
Here, we report on high-performance Li metal batteries under low-temperature and high-rate-charging conditions. The high performance is achieved by using a self-assembled monolayer of electrochemically active molecules on current collectors that regulates the nanostructure and composition of the SEI and deposition morphology of Li metal anodes.
In the field of battery thermal management systems (BTMS), low-temperature heating is a core technology that cannot be ignored and is considered to be a technical challenge closely related to thermal safety.
A temperature-rise model considering the dynamic fluctuation in battery temperature and SOC is proposed, and it is possible to predict the battery temperature during the progress of battery self-heating at low temperature.
Given the added complexity, cost, regulations, and weight of such systems, directly innovating and advancing the battery chemistry itself to be able to withstand lower-temperature conditions has been and will continue to be vital in enabling EVs, space missions, and other complex low-temperature applications.

Here, we realize high-rate low-temperature sodium metal batteries (LT SMBs) through modulating electrolyte chemistry. By introducing a weak Na + solvating co-solvent, tetrahydrofuran/1,2-Dimethoxyethane (THF/DME), the kinetic barrier for Na + desolvation is significantly mitigated.
Through large-scale screening, the researchers concluded that the optimal "soft" solvents should have a relatively low DN (less than 10) and high dielectric constant (greater than 5) values, and ultimately realized a high-performance, low-temperature Li-ion battery that retains more than 83 % of its room-temperature capacity in a practical pouch cell after 300 cycles at …
In the high-low staggered "U" type runner structure, when the fluid inlet flow rate is greater than 1 m/s, the temperature difference between the fluid and the battery tends to stabilize, and the temperature difference between the fluid and the battery is basically stabilized at about 6 and 3°C after heating.
Furthermore, the performance of LIBs is very sensitive to their operating temperature. Low temperature can cause battery polarization, sudden performance degradation, and even battery failure [12], [13], [14].The most direct and feasible way to improve the low-temperature performance of LIBs is to optimize the low-temperature performance of their …
