What causes a lithium battery pack to malfunction?

However, failures can cause lithium battery packs to malfunction. The type of problem will be based on the construction of the battery pack, how it is charged, how it is used and handled, and environmental factors.

How does charging and discharging affect lithium-ion battery degradation?

The cycle of charging and discharging plays a large role in lithium-ion battery degradation, since the act of charging and discharging accelerates SEI growth and LLI beyond the rate at which it would occur in a cell that only experiences calendar aging. This is called cycling-based degradation.

What causes a lithium ion battery to degrade?

Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.

What happens if a lithium battery pack catches fire?

One of the main issues that we hear about constantly in the news is when a lithium battery pack has caught fire in a smartphone, laptop, or other device. Then the manufacturer has to institute a massive recall for the battery packs.

Why are step-change advances in lithium ion battery performance a problem?

One of the major issues that has hindered step-change advances in LIB performance is the decline over time in the charge that a battery can deliver (defined as ‘capacity fade’), and its impact on performance. A key location for electrochemical degradation processes is the interface between the electrolyte and the electrode active particles.
