The common tendency of phones heating up has pertained over the ages but it is only recently that this occurrence has caused major damage to the safety of its users. The constant use of the smart phone for long hours can cause the battery to heat up and this may also be experienced when the phone has been kept for charging. The latest catastrophic incident of the Samsung Note 7 bursting into flames has shocked the world and started a ripple that has generated concern amongst the producers and consumers. Scientists have invented a new technique that can exterminate the fire caused by heating of the batteries.
According to information received from PhoneArena, the lithium-ion batteries have not been made completely safe for use over the years but now the Stanford University researchers have developed an experimental "Li-ion" battery which contains a certain fire retardant that acts as built-in fire extinguishers of the phones. The new model of the battery includes layers of the flame-retardant called "triphenyl phosphate" which separate the two electrodes.
Further details about the fibers used in the "Li-ion" batteries are explained in Science News regarding the design, structure and functionality. It explains that the fiber resembles the structure of an éclair filled with cream because this fire extinguisher in the battery consists of a plastic shell that is filled with the flame retardant. When the conditions in the battery are normal, the plastic shell conceals the flame retardant, to prevent any spillage into the electrolyte. If the same battery experiences extreme amounts of heat, the plastic will melt and the flame retardant will escape which can exterminate the flames within a fraction of a second.
The battery unit is designed in such a way that the chemical is released only when the battery reaches a critical 150 degrees Celsius (302 F) temperature. This process could result in the hike of phone prices all over the world because the process of making such batteries is expensive and troublesome. A lot of detailing and intricate work is involved and, making the same for all the lithium ion batteries will be time-consuming.
The prices may increase but it also ensures your safety and the longer life of the smart phone.
