When the graphene batteries can be commercialized?

Source: 2020 - 04 - 01 nothing hits: in choosing a mobile phone, the battery has become one of the important factors that we see, businesses are now in the use of quick charge, one of the cell phone battery as a selling point. As is known to all, now on the market most of the cell phone battery is lithium battery, but graphene is more useful than a lithium-ion battery batteries, there are rumors that graphene can be commercialized battery now! Recently, a company from the United States Los Angeles, said they have developed a kind of commercial graphene batteries for mobile phones, and ready to be used commercially. The battery has a capacity of 3000 ma, the use of 60 w charger, can be recharged in 20 minutes. Due to the epidemic, now we have to stay at home most of the time, mobile phone has become our main entertainment. We all have a common concern, after a long time to buy mobile phones, the battery is useless, almost every two hours charging time, charging time more than an hour, the process of waiting is a long and difficult. Assuming that graphene battery can buy in the market, and can charge the battery in 20 minutes, we must concern will be resolved. In addition, compared with the normal lithium battery, battery graphene is more practical, cycle count up to 1500 times, is the 3 - batteries 5 times. In other words, if the phone need every 3 - 4 hours charge time, as long as you use the graphene batteries, cell phone use more than 10 hours there will be no problem, it also solved the problems of many users to worry about frequent charging. Battery technology is rarely appeared in the news, but it has become a key point of many technology companies demand. Lithium-ion battery is currently the most widely used in mobile phone battery, the battery life will over time shortened, so we are looking for a better alternative. Because of graphene is an important kind of conductor, it can be in the process of transmission, in the case of does not produce as much heat, transform power forward, so as to improve the efficiency of the battery, prolong the service life of battery. Although graphene much-hyped batteries, but it has a fatal flaw: it's too expensive. According to data, the cost of one kilogram of graphene is about 300000 dollars. High prices is a major cause of graphene is not yet commercially available battery, mobile phone manufacturers should explore other battery technology, rather than pay big money to buy. But now the graphene battery can be used commercially, the price may be different. Do you have any idea?
