On Oct. 13 Samsung recalled all Note 7 phones. Every U.S. carrier must again shut down production. Samsung Note 7 phones stirred up attention after several batteries overheated and exploded.

The explosions were due to “a very rare manufacturing process error” according to Samsung on its British website.

The Washington Post explained the product catching fire are lithium-ion batteries, which have the possibility of being dangerous. The lithium-ion batteries are catching fire, causing concern for the safety of the devices. However, these types of batteries can contain a large amount of energy, and there is no replacement.

According to The Washington Post lithium-ion batteries contain two electrodes, where electricity can enter or leave. There is a barrier between the negatively and positively charged electrodes, because if they touch there’s a chance of it catching fire.

“Sometimes technology goes too far, and this is one of those instances,” Tyler said M ‘19.

Exploding batteries is far more common than is believed. According to CNN a variety of problems cause lithium-ion batteries to explode. It can be a result of mistakes in the charging process, overheating and bad manufacturing. It is believed the phone’s batteries were too tightly packed causing the explosions.

CNN explained Samsung has not been the only company to face technical issues with their devices. In 2016, HP and Sony had to recall computer batteries and about 500,000 hoverboard for being fire hazards. In 2013, 787 Dream liners had to be grounded for risk of catching fire.

These type of batteries can be potentially hazardous, but the risk is extremely low. All Note 7 phones have been recalled, and Samsung is offering safe replacements to those who bought them.
