AG11 battery.Why is battery technology developing slowly? Why the graphene battery claimed to “change the world” hasn’t arrived yet

　　Smartphones have been one of the fastest growing industries over the past decade. Whether it is the system or configuration, photo functions or unlocking solutions, earth-shaking breakthroughs have been made. Among them, the most powerful is the fast charging technology, which changes from 20W fast charging to 50W fast charging. Not long ago, Xiaomi mobile phones developed 100W ultra-fast charging. I don’t know if you have noticed that the mobile phone battery itself seems to have not changed. At most, the capacity has increased a little. Why is this happening? I want to know if you have ever taken the battery of an electric car? Although it is small in size, it weighs dozens of kilograms and many girls cannot carry it. High-end flagship phones from so many manufacturers do not necessarily need to be equipped with large-capacity batteries. This is because firstly, the thickness of the phone must be increased, and secondly, it will appear too heavy when held by the user, affecting the feel. According to statistics from some netizens, the charging life of lithium batteries is generally less than 2,000 times, while large-capacity batteries take a long time to charge and are prone to heat. On the contrary, the charging time and service life of the battery are lower than that of the small capacity battery. I believe people don't want problems like this on their phones. Some people say that whoever can break through the current battery problem will be the second richest person in the world. This may be exaggerated, but it must be said that battery is one of the most requested features in smartphones right now. If there is a breakthrough in battery technology, smartphones will inevitably change with that breakthrough. Not long ago, it was reported that Samsung Electronics had applied for a patent for graphene batteries. For a while, opinions were divided. Graphene should be the most talked about material in recent years, but graphene batteries have not been really commercialized although they have always been a hot topic. Why is this? In 2010, the discoverer of graphene material won the Nobel Prize, so this new material well known to the public. Huawei founder Ren Zhengfei said that the biggest future disruption of this era will be graphene. In the next 10 to 20 years, graphene will undergo a technological revolution. Current data shows that the capacity and life of graphene batteries are several times that of ordinary lithium batteries, but the cost is only a quarter of that of ordinary lithium batteries. A graphene battery with the same capacity weighs half as much as a lithium battery. A 5,000 mAh graphene battery can be fully charged in half an hour. In other words, compared with ordinary lithium batteries, graphene batteries have only advantages and no disadvantages. Not long ago, Samsung China posted on Weibo: The phone is out of power? Graphene batteries can use lithium ions to shuttle and move quickly and massively between the graphene surface and electrodes, and a new type of graphene battery has been developed. Even in a high temperature environment of 60 degrees Celsius, it can increase the battery capacity by about 50%. It can be fully charged in just a few minutes. Graphene material can also be made into a new type of graphene self-heating floor, which uses graphene material to generate heat during the high movement of carbon molecules to achieve a heating effect. Perhaps in the future, when graphene technology is truly mature, it will bring convenience to our lives. Let’s wait a little longer!
