Samsung has recalled all its Galaxy Note 7 smartphones after a series of fires and explosions. At first Samsung was offering replacement phones, but when these too showed a tendency to explode, Samsung has now apparently pulled the entire product line. And it is now against the law to even take one of these devices on board a commercial flight.
Like most other electronic devices, the Galaxy Note 7 is powered by a lithium ion battery. It has been known for years that lithium ion batteries can experience something called “thermal runaway.” When this happens it creates the possibility of a fire or an explosion. Fortunately, this is very rare but Samsung’s Galaxy Note 7 seems to have a higher probability of experiencing this problem.
As consumers demand faster and faster devices with shorter charging times manufactures may be pushing the limits of lithium ion technology. This can lead to disastrous results. Most of the lithium ion batteries used in Samsung’s Galaxy Note 7 smartphones is actually supplied by its affiliate, Samsung SDI Company, Inc… However, some of the batteries used in the Galaxy Note 7 may have been supplies by Amperex Technology, a subsidiary of TDK Corporation, a Japanese company. The Samsung SDI batteries are manufactured in Cheonan, South Korea and in Tianjin, China but put together in a Vietnamese facility.
