Why have mobile phone batteries stagnated for so many years? Explore the current status and problems of battery development

When it comes to today's mobile devices, to be honest, the rapid development often makes me raise eyebrows.

Before this, I had never thought that the young Nokia would one day change itself and continue to develop towards a large screen.

This is also a microcosm of the development of today's mobile phones. With the extreme development of science and technology, today's electronic equipment has undergone very powerful upgrades.

In terms of mobile phone chips, today's SOC architecture undergoes new innovations every year, and in terms of processing speed, it also undergoes about 60% upgrades every year. Today's mobile phones are already capable of a small number of "desktop-level operations", and this is the main reason.

In terms of cameras, with the development of the sensor industry, today's portable cameras have also shown their strength.

The large xenon cameras of the past have long since ceased to exist. Leica lenses, led by Huawei, have gone global, producing effects comparable to those of small SLR cameras.

Not to mention the development of manufacturing technology, everyone should know how inferior the previous mobile phones were, which is why the iPhone 4 received astonishing reviews.

Today’s mobile phones are extremely delicate. The aluminum alloy one-piece design has fallen behind, and the new plain leather design has arrived. Every move is exquisite and beautiful.

However, I don’t know if you have noticed that while other technologies are developing at their best, mobile phone battery technology seems to have stopped, and we do not feel that there is any big development.

At least it didn’t give us a deep sense of experience, or it might have been obscured by the various improvements I mentioned above.

The most intuitive feeling brought about by this is that today’s mobile phone battery is really becoming less and less durable. Before the development of mobile devices, our mobile phones could only be charged once a day at most.

Now, I really don’t know how many times I need to charge it every day. If you go out for a little longer, you have to bring a power bank, otherwise a sense of panic will hit you instantly.

The above leads us to question why mobile phone battery technology is not developing very fast. Why has the problem of short mobile phone battery life not been solved for so many years? What's the problem?

At present, the batteries on the market are basically lithium batteries.

The reason is naturally very simple, because lithium has the best energy storage capacity among all known metals, and it is also cheap and easy to promote and popularize.

We should also be fair here. It is not that mobile phone batteries have not developed in recent years, but have developed very rapidly. They have just been beaten by the current development speed of mobile phones. .

For example, the lithium batteries in mobile phones ten years ago are definitely incomparable to the lithium batteries in mobile phones now. The reason why today we feel that the battery of mobile phones is not enough is because the definition of mobile phones has changed greatly.

Ten years ago, mobile phones used small black and white screens, but now mobile phones use large color screens.

In the past, mobile phones only needed to complete the task of making calls or sending text messages. At most, they could add a greedy snake.

Needless to say, now, mobile phones have become a tool for us to understand the world. Communication, games, social networking, and entertainment are all integrated into mobile phones, and their power consumption has naturally doubled.

According to some current data, mobile phone batteries are improving by about 3% every year, which means that in the past ten years, mobile phone battery technology has only improved by 34%.

According to development standards, mobile phone batteries are not without progress.

Only compared to the terrifying rate at which the performance of today's high-end chips doubles every 1 to 2 years, everyone feels that today's mobile phone batteries seem to have no development at all.

To be honest, when it comes to improving the battery life of mobile phones, it is often not us who care most about it, but the major mobile phone manufacturers.

If this incredible technology were developed, wouldn’t it mean that it would have a world-wide reputation and a huge market? Maybe you won’t have to do anything else in the future, just selling the license fee will be enough for your lifetime.

However, even though various mobile phone manufacturers have tried their best, they cannot come up with a solution that has the best of both worlds. The biggest obstacle is the issue of mobile phone portability.

Today’s mobile phones are pursuing thinness and lightness, and to achieve thinness and lightness, we have to reduce the battery capacity.

In previous years, many mobile phone manufacturers actually pursued the ultimate in thickness of mobile phones. But later on, because the battery life was so poor, the gain outweighed the loss.

Although they have figured out the key now, they are limited by the space inside the mobile phone, so the battery life can only be considered average. Therefore, there are two solutions before them:

The first is to increase the thickness of the mobile phone, and the second is to increase the size of the mobile phone.

These two are the main reasons why today’s mobile phones are becoming larger and larger, and I have to say that they are really a bit difficult. Due to the greater power consumption brought about by large screens and high-performance chips, the effective service life of mobile phones is now fixed at about two years.

This undoubtedly makes many mobile phone manufacturers happy. After all, the faster users’ mobile phones wear out, the easier their lives will be. This is really another portrayal of a businessman and a traitor.

Of course, the development of science and technology cannot rely solely on physical expansion.

On a technical level, many scientists have also lost their hair. The solution they gave was to solve the problem by increasing energy density, but it seemed to bring more problems.

Current scientific researchers can only make their own efforts in electrolyte and positive materials to barely improve the battery life by a small amount.

But just when they want to celebrate their achievements, other aspects of mobile phones will usher in a new round of progress, and battery life will also increase.

Therefore, to users, mobile phone batteries seem to have not changed for many years.

Years of hard work are nothing but nothing in the eyes of everyone. This may be something worth spitting out blood.

In line with the principle of becoming more courageous with every setback, these scientists do not care about other people's opinions. After all, they are so selfless and motivated that they only care about their achievements and achievements.

It has to be said that although today's battery technology is improving by about 3% every year, all this is still not enough in the face of the rapidly developing chip technology and screen technology.

Therefore, when mainstream battery technology is difficult to develop, some bypass methods are recognized by many technicians.

I believe everyone knows that in the years when various mobile phone assistants became popular, some so-called power control software also emerged. Although the gimmick is indeed not small, in my opinion it is indeed of little use.

Trickle charging and so on are all nonsense - the typical value of a mobile phone battery is so large, how can you explain it in just one sentence?

Later, various mobile phone manufacturers led by Huawei introduced fast charging technology due to the lack of efforts of scientists. It has to be said that this is a relatively alternative solution, and it is very effective. .

The charging time that originally took about three hours has been shortened to about one hour because of this function.

According to some current news, Xiaomi has pushed fast charging technology to the 100W position, which is undoubtedly a very scary data.

All in all, scientists from all walks of life today are doing their best to solve this problem, and they seem to have gained a lot.

On a technical level, Huawei has also launched the so-called graphene heat dissipation. Although this does not seem to have much to do with batteries, it is still a major road.

As the saying goes, all roads lead to Rome. There are many ways to solve problems in this world, why should we just stick to the few methods that are currently within our reach?

But I really look forward to when the phone can be charged every two days, which is really important for my amnesia.

There are now many reports on graphene batteries, but this technology is currently only in a theoretical state. Since the current manufacturing process of graphene is not good, this can only become a dream in our hearts.

Although many citizen scientists are arbitrarily promoting the method of increasing energy density to increase battery capacity, and they are talking nonsense on the Internet.

However, in my opinion, this is still not a smart approach.

Let’s first talk about the risks of increasing battery energy density. In order to ensure that the battery capacity is large enough, the bigger the battery energy density, the better. However, everything must be reversed. Increased battery energy density may also bring about risk.

Technically speaking, increasing the energy density of batteries is definitely the simplest way. However, according to the current technology, you are likely to earn a giant bomb for this.

From a purely structural point of view, the mobile phone looks like an ideal explosive body - an iron shell enveloping an energy body, and the reason for the explosion is that the energy is concentrated in a closed space. Cannot spread internally.

Therefore, when it comes to batteries, there is really no room for perfunctory performance.

There is currently an international research and development direction that believes that all these problems can be solved by making the battery separator thinner and lighter.

As we all know, there is a separator inside the mobile phone battery to isolate the positive and negative electrodes of the battery cell. Once the separator is damaged, it will cause the positive and negative materials to short-circuit, causing a fire or explosion.

If the separator is thinned in order to increase the battery capacity, the mobile phone will become extremely dangerous.

Therefore, experiments on various processes require a long process of demonstration. It is obviously very irresponsible to talk nonsense simply based on a so-called idea.

But no matter what, mobile phone batteries will have greater development in the future, and all of this will undoubtedly change our lives. There is no need to push this industry to progress. After all, when it comes to energy bodies, everyone still has to put safety as the first priority.

We would rather it appear late than let it appear in front of us in an unsafe manner - such as an explosion.

Although before this, we all thought that the development of mobile devices changed our lives. However, if we want to trace the origin, this change in equipment is mainly due to the great development of battery technology.

In today's technological development direction where everything is mainly oriented to electric energy, we still need to use electric energy as the main energy source. And this means that all changes in our lives require the blessing of electrical energy.

Just as people a hundred years ago would not have thought that huge lead sulfate batteries could be continuously shrunk into lithium batteries as large as today.

From protecting all the changes around us, to changing our living conditions.

We would never have imagined that the useless mobile devices we once despised would gradually become a part of our lives due to changes in battery technology.

In this world, every change in technology involves the efforts of countless people, and also means the development and transformation of hundreds of components.

While we are committed to complaining about the lack of development of battery technology, we should also think that after this, hundreds of bald-headed scientists are constantly attacking this and are committed to Change our lives.

In any case, on the premise of ensuring safety, let mobile phone batteries develop like this. Even if it is slow, great changes will happen. We believe that sooner or later, we can use another round of battery development to achieve a new round of changes, and even completely change our philosophy of life.

What we need to do at this time is to wait for the future.
