IT House August 13th News About Samsung's action to make graphene batteries has long been rumored. According to CNET today, according to Twitter, Evan Blass (@Evleaks) said that Samsung hopes that at least one mobile phone will be equipped with graphene batteries next year or by 2021.
“As far as I know, Samsung hopes that at least one mobile phone will use graphene batteries next year or 2021,” Brass said in a tweet on Monday, “The battery can be fully charged within half an hour, but they still Need to increase production capacity while reducing costs. ”
In response, Samsung did not immediately respond to the request for comment.
In fact, as early as November 2017, Samsung obtained a patent based on graphene battery solution. According to previous reports, this graphene battery has been basically manufactured by the end of 2018. At present, Samsung has applied for patents in Korea and the United States.
This technology is called "graphene ball", it is reported that Samsung's graphene solution can make the battery charge 45% higher than lithium battery, that is, using graphene battery, you can change the existing In the case of the size of the battery, double the amount of electricity. The charging efficiency of graphene batteries is more than 5 times faster than that of traditional lithium batteries. In addition, the graphene battery is expected to be cheaper than the lithium battery after mass production, and because of the material relationship, it will be more environmentally friendly. Graphene maintains extremely high stability in high temperature environments up to 60 degrees Celsius. Therefore, the successful development of graphene is expected to become the power source of electric vehicles in the future.
Following the 2016 Note 7 fiasco, Samsung began researching battery replacements. At the time, shortly after the listing of Note 7, users were overheating. Samsung blamed these problems on battery design flaws and recalled all Note 7 phones on the market. However, the problem has not been solved, and there has been an overheating problem after replacing the device. Samsung had to recall and stop production Note 7 for the second time.
