Samsung figures out how to increase battery life of phones

One of the biggest problems associated with phones, be it a smartphone or normal one, is the battery life. However, with technology, the researchers have been able to develop batteries that can last for very long periods of time. The present Li-ion batteries that are widely used in mobile phones are a member of a family of rechargeable batteries. The working of these batteries is quite simple. The lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. A Li-ion battery serves for a long time before it finally dies out. Due to this, they are very reliable and can be easily developed. The smartphone owners know what the value of battery life is. You can go on long trips knowing that your phone won’t be needing a recharge soon. A long battery life can be the deciding factor for some the buyers while others just look for a respectable time of backup that the battery would provide.

However, soon there won’t be a need to be worried about the backup. According to a new study published in a journal last week, these li-ion batteries might provide twice the backup in the near future. The study was published by the Samsung researchers and claims that the new technology can enable the batteries to provide up to 1.5 to 1.8 times the current backup. If such a technology is developed it can not only be useful in the smartphone market but can be put to use in many other areas.

The report says that Samsung has come up with a new coating technique for the battery cathodes that promises to overcome the current limitations of the current batteries. A Li-ion battery might be easy to manage but it lacks the protection that is required to maintain its safe operations. Sometimes it also reported that these batteries explode due to overuse or overheating. Noticeable deterioration can be seen in the battery after one year use and this is mostly overlooked by most of the manufactures. However, the researchers and manufacturers are coming up with new chemical combinations to enhance the performances of these batteries.

As per the study, which appeared in the Nature Communications, the new battery technology that involves the use of grapheme on the silicon surface offers volume expansion that provides it with increased battery life.

The Nature Journal says,” The grapheme layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent grapheme layers When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free grapheme allows the full cell to reach volumetric energy densities of 972 and 700Wh1-1at first and 200th cycle respectively.”
