Incorrect use When lithium-ion batteries are exposed to special temperatures and humidity or are subject to impact, metal friction, or poor contact, the instantaneous current may be excessive, which may cause the battery to short-circuit and explode. Part 3. What are the dangers of short circuiting lithium batteries? 1. Battery leakage
Fortunately, most lithium batteries do have short circuit protection mechanisms built-in. These mechanisms are designed to detect battery short circuit and prevent excessive current flow, which can cause the battery to overheat and potentially catch fire.
The extremely strong current during a short circuit will cause the battery resistor to heat (Joule heat), which will likely damage the device. A shorted battery is a bad failure. The chemical energy stored in the battery is lost as heat and cannot be used by the device. At the same time, a short circuit can also cause severe heating.
This usually happens during some-or-other incident, but it can also be the result of human carelessness or malice. Short circuiting a battery deliberately, or accidentally connects the positive and negative battery nodes, forcing them to be the same voltage. The result, as Wikipedia puts it aptly, is a connection with almost no resistance.
When the cathode and anode of a battery are connected directly, bypassing the internal resistance of the battery, a short circuit occurs in the battery. As a result, a large current flows through the short circuit, creating heat and possibly causing the battery to leak or explode. There are two main kinds of battery short circuits.
An electrode releases electrons into the circuit. At the same time, the other electrode picks up electrons from the circuit. This overall favorable chemical reaction drives the flow of electricity in the circuit. What is Li-ion battery short circuit?
