Samsung makes breakthrough in production of longer-life batteries for smartphones; could also be used in cars


Researchers of Korean giant, Samsung Electronics, recently announced that they have developed a breakthrough technology which will hopefully provide longer lasting capacity for batteries of smartphones and other devices.

Published in an online academic journal Nature Communication, the study was able to make conductive high crystalline graphene combine with silicon carbide substance effectively. It was then used to coat lithium-ion batteries. This new technology was tested and the result showed that the battery lasted up to almost two times longer than most regular lithium batteries.

In theory, if a smartphone user is able to use his phone for  12 hours before he needs to recharge, the improved battery can give him up to 21 hours, Engadget shares.

Samsung Advanced Institute of Technology professional researcher Son In-hyuk said that the research team will continue to improve the new technology.

“The research has dramatically improved the capacity of lithium-ion batteries by applying a new synthesis method of high-crystalline graphene to a high-capacity silicon cathode. We will continue to improve the secondary cell technology to meet the expanding demand from mobile device and electric vehicle markets,” Son said to Korea Times.

The report also mentioned that silicon, which is expected to produce 10 times power capacity, was first mixed with graphite, the common raw material use for lithium batteries. This made the battery life degrade drastically by repeated charging.

Even though graphene is a relatively new material for such purpose, the researchers found that the new combination was able to produce a capacity four times more than graphite and may also prove to be more durable.

The newly patented technology can also be applied for batteries in cars. However, it may take a few more years before it becomes commercially available for both vehicles and gadgets. 

Techaeris noted that it may also come in handy with the non-removable battery of Samsung Galaxy S6 which is said to receive poor reviews because of its battery life and the inability to replace the battery.
