Lithium-ion batteries are used in a range of devices: electric cars, cellphones, airplanes and laptops to name but a few. This is a main source of power for modern technologies. On the other hand, these batteries are also the main source of many problems. In some cases they overheat, explode and in some instances catch fire.
The most recent damaging case caused by battery faults is the explosion of Samsung smartphones across the world. Samsung is the leading globally in the manufacture of smartphones.
On Friday, the company announced its intention to recall the Galaxy Note 7 model. This decision was reached after finding a fault in the batteries that had lead into fires in number of reported cases.
The company intends to replace 2.5 million smartphones which had been sent to retailers across the world. This sets a record as the largest recall in the industry.
