Samsung invents a battery recharging five times faster

The group has patented a graphene battery process that allows complete charging in fifteen minutes.
After the fiasco of the Galaxy Note 7 explosive batteries, will Samsung make up for it with revolutionary batteries? The South Korean conglomerate has developed a process that is supposed to make lithium-ion batteries last longer and recharge them faster.

The research group at Samsung Electronics has succeeded in synthesizing “graphene balls” which, integrated with a smartphone, would increase its autonomy by 45% and allow it to recharge completely in just 12 minutes, against about an hour for the current batteries.

Graphene, isolated for the first time in 2004 by the University of Manchester, has since been announced as the material that will succeed silicon and revolutionize the storage of energy. Present in any pencil mine in the form of graphite carbon, it has a very good conductivity, which reduces the risk of overheating when incorporated into a battery and allows faster loads.

“Three-dimensional popcorn”
Proponents of this material claim that it will make phones so thin that they can be integrated into sheets of paper or tissue. A graphene sheet is indeed a million times thinner than a hair and this film is able to be folded multiple times.

Using a method described in an article in the journal “Nature”, Samsung researchers used silicon dioxide (SiO2) to synthesize graphene in a form resembling “three-dimensional popcorn”. The group has filed a patent application for this technology in South Korea and the United States, reports the “Financial Times”.

Mass production in several years
However, this popcorn of the future is not close to being integrated into the next Galaxy S9 brand. “It’s great technology with a variety of potential applications, but it will take a long time for the graphene-based batteries to be mass-produced,” SK Financial’s Kim Young-woo told Financial Times.

Research on this super material is, moreover, still buzzing. By the end of 2012, there were already more than 5,000 patents filed on graphene, according to a census of a British cabinet, and in 2013 the European Commission announced funding of one billion euros to support ten years of research on this material.
