As a result, when the lithium-ion battery was short-circuited externally, the battery temperature rose rapidly to the maximum temperature that the battery can rise. The highest temperature caused by external short circuit appeared in the case of a single battery. The higher the SOC, the faster the battery temperature rose.
Cai et al. studied the experimental simulation of internal short circuit of lithium-ion battery polymer . They found that the risk of thermal runaway during an internal short circuit increases as the battery’s state of charge (SOC) increases.
External short circuit has a severe influence on lithium battery’s performance. Currently, a huge study has focused on the single battery’s short circuit. However, cells are often interconnected into a module in real applications.
Shriram et al. performed a systematic study of the internal short circuit mechanism inside a lithium-ion battery . They found short circuit between lithiated anode material and aluminum current collector, resulting in maximum heat generation.
Chen et al. found that the higher the state of charge (SOC) during a short circuit leads the battery to heat up more quickly and inflict more damage, and a lower SOC lowers the short circuit current and lessens damage while releasing more short circuit capacity . Kriston et al. divided the battery short-circuit current into 3 stages.
External short circuit would accelerate the rate of increase in internal resistance of lithium-ion battery. Normally, the internal resistance of the battery doubled at approximately 350 cycles. After external resistance, when number of cycle reached 170 times, internal resistance doubled.

In this paper, a diagnostic method for identifying an external short circuit (ESC) fault for a lithium-ion battery is developed based upon active characterization experiments and online validation. The proposed method examines three criteria: voltage variation, current variation and temperature change rate. These criteria can be used to identify the fault independent of the battery state of ...
Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a compressive shock. A prolonged internal short circuit results in self discharge in combination with a local temperature increase. The latter effect is important because the electrolyte may start to decompose by exothermic reactions if the temperature reaches above …

When a lithium battery is short-circuited, a spark can ignite the electrolyte instantly. This is because the electrolyte consists of flammable liquid. The burning electrolyte will ignite the plastic body and cause the lithium battery to burn. If there are flammable materials around the lithium battery, it will cause a fire. 3.
Lithium ion battery technology has played a big role in the advancement and user experience of electric vehicles and other consumer electronic products. As market competition increases, manufacturers are striving to reach higher power densities and throughput in production.

The short-circuit current of a battery will depend on its voltage, chemistry, size and internal structure. We can usually simplify this to a simple model of an ideal voltage source and an equivalent series resistance. It should be clear from the model that the voltage at the battery terminals will droop with increasing current. With the values I''ve made up for Figure 1 …

The lithium ions do not migrate voluntarily, this is forced by the fact that a higher voltage is applied to the cell than it has at the moment. The migration of the lithium ions from the cathode to the anode continues until the open-circuit voltage of the cell corresponds to the applied external voltage – i.e. equilibrium is reached. Exactly ...
