The Next Real Battery Technology Breakthrough How Many Years Do We Have To Wait?

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, as long as the battery is made 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. Is battery technology so important that it is not 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 creating 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 even a slight imbalance in the composition of the internal materials can cause serious problems.


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 seem do 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 mobile phone top ten days. The problem is that such a battery becomes a very dangerous explosive.


Why is this so? When the battery is charged and discharged, the graphite will expand and contract by about 10%. We can deal with 10%, but silica can reach 300% on this. You don't have to think about how dangerous this battery is.


It is precisely because of this that the investment in battery technology research can be said to be a black hole that can't be seen in the end. Therefore, although many scientists, enterprises and research institutions in the world are constantly tackling the problem, they can't see the prospects, so these efforts are always They are fighting each other and cannot form an industry-wide cooperation.


More importantly, the Samsung Galaxy Note7 series of events shocked the entire industry, which also made people become more cautious in research, pay more attention to each step of the test. Industry insiders revealed that many manufacturers have begun to have a chance to force the growth of battery energy density. The battery event is a wake-up call that forces everyone's rhythm to slow down - of course, safety is definitely a good thing.


Can we see progress?

Then the question is coming: Since the progress of the breakthrough has been so slow, when can we see the progress of progress? Interestingly, the answer is a long time later, but it doesn't seem to be that long.


"It takes about 10 years to develop a new chemical process and 100 million pounds of investment, so it can't compare with the microprocessor field on the economic scale." Professor Wu said.


Moreover, 10 years is only the first stage. It will take another 10 years to continuously test and improve, so that the new technology is safe and stable enough, otherwise it can not be applied to commercialization. The simplest example, the research results of lithium-ion batteries was first published in Oxford in 1980. It was not until the 1990s that Sony commercialized the technology for the first time.


"We already have another chemical solution, but it will take some time to arrive. People have been talking about sulfur or silica gel as a new material for batteries. Another kind of lithium-air battery is now the final solution. Solution. However, it takes one or two more than 10 years before it can be perfect.” Professor Wu said.


10 or even 20 years is terrible for everyone, but after hearing the desperate conditions of the past, it seems that it is not that long. More importantly, the manufacturers have taken a different approach, and the progress and optimization of the piecemeal will certainly be there.


Although battery technology can't be broken in a short time, other technologies cannot be improved. As the performance of mobile phones continues to increase, the resolution even goes up to 4K, which puts stringent requirements on energy optimization.


In this regard, 10 nanometer process and even 7 nanometer process have been on the agenda. OLED screens can effectively reduce energy consumption. Optimization at various software levels has also become a compulsory course.
