Not only was the augment of internal pressure inside the battery associated with Pi and Pele, but also gas release was involved in the growth of internal pressure, as shown in Eq. (7). (7) P in = P i + P ele + P g where Pg is the pressure of gas release inside the battery (kPa). 3.3.
Basing on the analysis, the gas release temperature calculated by internal pressure is about 5 K lower than self-generated heat temperature. Before SV, the electrolyte volatilization and gas releasing are decoupled, and the gas release is about 0.009 mol. The internal pressure evolution of battery can be divided into three stages.
So, the increase in the battery temperature brought about the gas expansion inside the battery, which was the main reason for boosted internal pressure, as shown in Eq. (2). (2) P in = P i where Pin is the total internal pressure of the battery, Pi is the partial pressure of inert gas inside the battery.
The amount of gas release from the redox reaction inside battery is about 0.009 mol. H 2 and CO account for 35.2 % and 23.7 % of the gases at which the safety valve raptures, respectively. This work investigated gas release and heat generation inside the large-format LFP batteries by ARC test.
The battery expansion force can also indirectly response to the pressure variation inside the battery .Using this method, Li et al. found that the internal pressure of NCM batteries grew with a faster rate than that of LFP batteries at the early stage of TR. The researches on the internal pressure of battery are summarized in Table 1.
This paper addresses the safety concerns associated with LCBPs and proposes an effective solution for explosion relief. Installing an electric-controlled pressure relief valve with battery fault detection capability on a liquid-cooled battery pack can prevent explosions caused by thermal runaway. 1. Introduction
