Dear all Samsung Galaxy Note 7 users and fans, we would like to unveil to you on the reason why Samsung Galaxy Note 7 has an overheating or an exploding battery problem when in use or when in charge. This is mainly due to a short-circuit in the packed body of the slim phone in which has a tightly stacked battery altogether.

According to Forbes, when materials inside a cell move around, the electrically insulating layer that separates electrodes can tear, causing a short-circuit that creates a spark. “Even the tiniest spark inside a battery is enough to initiate the thermal runaway process,” says Donal Finegan, a chemical engineer at University College London.

This means that the battery is so slim and so tightly packed that the lithium ion battery’s positive charge and negative charge can leak to each other quite easily if there is a puncture between the plastics that separates them. That is why the name is “short-circuit” due to the circuit, which is suppose to be longer to function properly, being cut short and causing a havoc or a fire in the system.

Not to mention that lithium ion liquid is highly flammable as well. But according to Finegan, what makes a battery great at powering gadgets also makes them vulnerable and easy to catch fire as well. So if you have a Samsung Galaxy Note 7, return it for a refund quickly.
