Lithium-ion batteries (LIBs) have the advantages of high energy/power densities, low self-discharge rate, and long cycle life, and thus are widely used in electric vehicles (EVs). However, at low temperatures, the peak power and available energy of LIBs drop sharply, with a high risk of lithium plating during charging.
In general, from the perspective of cell design, the methods of improving the low-temperature properties of LIBs include battery structure optimization, electrode optimization, electrolyte material optimization, etc. These can increase the reaction kinetics and the upper limit of the working capacity of cells.
In general, a systematic review of low-temperature LIBs is conducted in order to provide references for future research. 1. Introduction Lithium-ion batteries (LIBs) have been the workhorse of power supplies for consumer products with the advantages of high energy density, high power density and long service life .
Two main approaches have been proposed to overcome the LT limitations of LIBs: coupling the battery with a heating element to avoid exposure of its active components to the low temperature and modifying the inner battery components. Heating the battery externally causes a temperature gradient in the direction of its thickness.
Even decreasing the temperature down to −20 °C, the capacity-retention of 97% is maintained after 130 cycles at 0.33 C, paving the way for the practical application of the low-temperature Li metal battery. The porous structure of MOF itself, as an effective ionic sieve, can selectively extract Li + and provide uniform Li + flux.
In terms of aging modeling, researchers identified the loss of active materials, lithium ions, and the reduction of accessible surface area as the main causes of battery degradation at low temperatures, and that the loss of conductivity at low temperatures is three times higher than at room temperature.
Challenges and limitations of lithium-ion batteries at low temperatures are introduced. Feasible solutions for low-temperature kinetics have been introduced. Battery management of low-temperature lithium-ion batteries is discussed.
