Once thermal runaway occurs, the volume of BVG may be large, and most of the batteries are closed in practical applications. Therefore, once the exhaust gas is ignited by the battery itself or other heat sources, it may cause the danger of explosion. Therefore, the research on the potential explosion hazard of BVG is necessary.
If the battery terminals come into direct contact, it can cause a short circuit, leading to rapid discharge and heat buildup, which may result in an explosion. Puncturing, crushing, or otherwise damaging a lithium-ion battery can breach its internal structure, causing a short circuit or other failure modes that can lead to an explosion.
It was also verified that the BVG explosion range increases as the battery SOC increases, revealed the opposite trend of the lower explosion limit with the multi‑carbon chain gas fraction, and in addition, the quantification of the explosion consequences provided recommendations on the SOC values for safe storage. 1. Introduction
In addition, 30 % SOC batteries have the narrowest explosion range and the lowest UEL, so it is recommended that packaged batteries or battery modules be transported or stored at 30 % SOC. The change in the lower explosion limit follows an opposite trend to that of the multi-carbon chain gas components.
BVG component analysis and in-situ explosion limit measurement experimental platform. The battery thermal control experimental platform is a hemispherical structure made of 304 stainless-steel with a 3 L reaction space and a stainless-steel flange at the bottom, which are fastened by eight M20 × 80 titanium steel bolts.
The BVG explosion limit in-situ measurement device is a capsule-shaped structure of 304 stainless steel with reaction space of 5 L. There are stainless-steel intake and exhaust pipes at both ends, and a glass window at the front side to observe the explosion phenomenon. The top has been equipped with a high-energy igniter for BVG igniting test.
