Lithium-Ion battery cell failures can originate from voltage, temperature, non-uniformity effects, and many others. Voltage effects can occur either due to overvoltage or undervoltage effects. Overvoltage effects happen when there is an increase in the charging voltage of the cell beyond the predetermined upper limit of 4.2 V per cell.

One in 5 (19%) businesses have experienced fires or explosions from lithium-ion batteries. However, many of these businesses are not following safety measures, putting them at risk. Aviva research suggests that more than half of businesses have experienced an issue linked to lithium-ion batteries, such as sparking, fires and explosions.
Lithium-ion batteries face safety risks from manufacturing defects and impurities. Copper particles frequently cause internal short circuits in lithium-ion batteries. Manufacturing defects can accelerate degradation and lead to thermal runaway. Future research targets better detection and mitigation of metal foreign defects.
