LITHIUM ION BATTERY THERMAL RUNAWAY

Lithium battery thermal capacity

The heat capacity of a mixture can be calculated using the rule of mixtures. The new heat capacity depends on the proportion of each component, the breakdown can be expressed based on mass or volume. The following breakdown of the components of a cell is based on an NMC chemistry [Ref 4]. Electrolyte increases the. . Tests of a Sony US-18650 cell [Ref 2] showed that the specific heat capacity was dependent on SoC: 1. NCA 1.1. 848 J/kg.K @ 100% SoC 1.2.. . The generic heat capacity values for cells of different chemistries are a good starting point for a thermal model. However, as the specific heat capacity is such a key parameter it is important to measure the actual cell being used. The specific heat capacity of lithium ion cells is a key parameter to understanding the thermal behaviour. From literature we see the specific heat capacity ranges between 800 and 1100 J/kg.K [pdf]
