No matter how many generations of smartphones are introduced, we always face an old problem: how the battery life is still the same. Regardless of how much optimization the vendor does, the final difference is in hours. Why the advancement of battery technology is always so slow, we actually talked about it before. When will the breakthrough come? Some new things can be said now.
As if impossible dream
Even if it is recognized that it has developed into a vertex of smart phones, we can see a lot of technical and design changes every year, such as the most topical OLED screen, large screen ratio design and so on this year. Of course, no matter how these things change, there are some things that we have become accustomed to, that is battery technology. The performance is constantly enhanced, the resolution is constantly improving, the camera is getting better and better, but the battery life is certainly not much breakthrough.
Of course, we have a way to improve the battery life, just make the battery bigger, but this is only the most rude way, the phone is so big. Almost all technical research can be solved by saving money and time. Battery technology is so important, isn't it worth the big manufacturers to invest?
The solution sounds simple, but it is not. It is not the key to solving the problem by investing a lot of money, hiring the best scientists, and having enough patience. The problem is that building a battery with a higher energy density will involve a whole new field of science.
Billy Wu, a professor at Dykes College of Engineering in London, explained that Moore's Law simply means that every few years the transistors become smaller, allowing the chip to accommodate more and increase processing power. This is not the case in the battery field. "In the field of microprocessors, everything is just to make things smaller. But on the lithium-ion battery side, if you want to increase the energy density, in other words, increase the battery life, then you must fundamentally Change the material in the battery."
Of course, this is not as simple as “just change the material†because the balance of the internal material composition may cause serious problems even if it is not correct. So many accidents now remind us how serious it will be if something goes wrong. Professor Wu said that the existing nickel, cobalt and manganese combinations may change in the next few years. Because nickel is more active, its proportion will increase, which will increase the amount of electricity.
Of course, only this change still takes years of testing to ensure that everything is stable and safe. It is said that if successful, the battery life can be increased by 10% to 20%. However, people have waited for so many years, and the upgrades and time they waited for did not seem to match. The real breakthrough in battery technology is as if people are chasing an impossible dream.
Difficult
According to scientists, battery technology can be said to be a "chaotic art." The reason why it develops so slowly is largely because almost every little progress or change requires a lot of experimentation and testing to ensure safety and stability. Even if you find a material that is helpful for increasing energy density, you can't guarantee that it will work.
For example, it has recently been found that silica gel seems to be a better material than graphite in current batteries. Its energy density is ten times that of graphite, which means that if our mobile phone can support one day, the silicone battery can make the phone top ten days. The problem is that such a battery becomes a very dangerous explosive.
