However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation. In extreme cases, these defects may result in severe safety incidents, such as thermal runaway.
In this study, it was found that two mechanisms are responsible for battery failure due to defects: one is the release of lithium on the negative tab, and the other is the dissolution and deposition of copper on the negative tab which mainly occur in the tab's edge area.
Lithium-ion batteries are currently the most widely used energy storage devices due to their superior energy density, long lifespan, and high efficiency. However, the manufacturing defects, caused by production flaws and raw material impurities can accelerate battery degradation.
In fact, the inherent bulkiness of battery energy storage quickly shows itself in real world applications. Using current technologies, half of the power produced by the battery pack of an electric vehicle goes to moving the batteries themselves, a basic problem for a mobile power source.
In extreme cases, these defects may result in severe safety incidents, such as thermal runaway. Metal foreign matter is one of the main types of manufacturing defects, frequently causing internal short circuits in lithium-ion batteries. Among these, copper particles are the most common contaminants.
In some extreme cases, batteries may catch fire spontaneously when not in use, often due to defects in their manufacturing process. For example, an electric vehicle got self-ignited without traffic accident in 2018, Hubei, China . These defects can accelerate performance deterioration, shorten battery lifespan and compromise battery safety.
