Model of Battery Capacity Attenuation at Low Temperature

Abstract

Lithium-ion batteries are widely applied for its advantages of being high in energy density, low in self-discharge rate, and high in maximal cycles, having no memory effect, and being pollutant-free. Accurately predicting the service lives of lithium-ion batteries is the important basis for reasonably working out battery replacement policy and ensuring safe use. For the purpose of this article, an acceleration model is devised for the valid period of capacity and the effect of temperature on lithium-ion batteries, revealing the pattern in the effects of capacity-related factors, and providing the fundemental data for the use of batteries at low temperatures.

Review on preheating systems for Lithium-ion batteries of electric vehicles under low temperature circumstance

“…All of these issues can lead to an undesirable driving range for electric vehicles. The study by Wang et al [4] shows the LIB discharge capacity meets a sharp drop when put into an environment below -5 °C. Specifically speaking, at -10℃, -20℃, and -30℃, the actual discharge capacity becomes 88.0%, 82.5%, and 32.79% of the desired capacity at room temperature, respectively.…”

Copper oxide@cobalt oxide core–shell nanostructure, as an efficient binder-free anode for lithium-ion batteries

“…Since the SEI layer is insoluble in organic solvents, it is stable in the organic electrolyte solution, avoiding damage to the electrode. This fact dramatically improves the cycling performance and service life of electrodes, causing high Coulombic efficiency [58][59][60][61][62]. The cyclic voltametery graph of the cobalt oxide@copper oxide NWs on the SS mesh in a LIB half-cell has been shown in figure 5(e).…”
