This paper reports in situ measurement of the radial temperature distribution inside a cylindrical Li-ion battery cell. 18650-size cylindrical cells with multiple micro thermocouples embedded are designed and manufactured.
Temperature has a profound impact on the performance of lithium-ion batteries. The temperature distribution in the cylindrical cell during charging and discharging cycles is governed by physical features of materials such as thermal conductivity and specific heat capacity. The cells must operate at their optimal temperature.
One way to analyze the temperature distribution in Li-ion batteries is with multiphysics simulation. In this blog post, we explore how to model the thermal distribution in a Li-ion battery pack and discuss a simulation app that is based on the model. Thermal modeling of batteries is commonly done using two approaches:
Analysis of the relationship between the lithium and electrolyte average distribution in the cell produced the following observations: at higher degrees of cell fatigue an accelerated capacity fading is observed, which is characterised by a fast consumption of electrolyte and no change in the average lithium concentration.
In situ monitoring of electrolyte crystallisation at low temperatures can help to quantify the amount of solid electrolyte in a lithium-ion battery and map its spatial distribution.
Considering the fact that local performance depends significantly on local temperature, the non-uniform current distribution in large format Li-ion battery cells 33 – 35 may be exacerbated by such larger temperature gradient. Figure 18.
