External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
Additionally, any excessive external pressure to the edge of the cell could cause a short circuit. This article will focus on the testing for burrs and particles inside the materials of lithium ion batteries. Figure 3.
Multiple requests from the same IP address are counted as one view. The internal short circuit (ISC) in lithium-ion batteries is a serious problem since it is probably the most common cause of a thermal runaway (TR) that still presents many open questions, even though it has been intensively investigated.
This is due to two main reasons: first, a short circuit in a series module can cause some cells to undergo polarity reversal (as shown in Fig. 15 C and D), potentially leading to electrode material damage, electrolyte decomposition, and gas generation, thereby accelerating battery degradation .
Avoid short circuiting a battery in several ways. Buy decent batteries and devices, and use them wisely. Never allow battery terminals to connect directly, or damage or modify the cells in any way. More Information Battery Chemistry and What It Is All About
