In recent years, the rapid development of mobile electronic device technology, more powerful processors, graphics cards, ultra-clear and even flexible screens are impressive. Unfortunately, the breakthrough in battery technology is slow. So far we still have to endure a battery life of about a day. Although we have been paying attention to the development of new material batteries, in fact, the most likely breakthrough in the near future is still lithium battery technology. Below, we take a look at the development of next-generation battery technology.

We currently basically use lithium batteries or lithium ion batteries in mobile electronic devices. Lithium batteries use lithium metal or alloys as negative materials and non-aqueous electrolyte solution batteries. They have a larger capacity and more capacity than previous nickel-metal hydride batteries. It has good stability and rechargeable and rechargeable characteristics. It has been quite mature after years of development. Almost all current consumer-grade lithium batteries are made of anode graphite. As for the shortcomings, through the news reports of frequent fires and explosions, we have also learned that lithium batteries are very easy to runaway and explode in the event of short circuit and overheating, which is why we encourage users to use original batteries, chargers, data cables to prevent lithium The battery is shorted.

Improved forms of lithium batteries are diversified, but the direction is basically established in terms of better safety, charging speed, flexible form and performance. Let's take a look at several new technologies that are expected to make breakthrough progress.

1. Faster charging speed

Nangyang University of Science and Technology's R&D team has developed a new type of lithium battery. The idea is not the same as other technologies, not to increase capacity, but to charge time. In just two minutes, you can quickly charge 70% of the power and charge more than 10,000 times. This technology uses titanium dioxide instead of graphite as the anode material, and Qualcomm also achieves a more stable charging effect through a better control chip. This technology is characterized by low cost and is very suitable for mobile products and the electronic automobile industry.

2. Non-flammable components

First of all, the safety of lithium batteries is the most people want to solve. Scientists have found that an organic solvent called PFPE is more stable, which can reduce the effect of crystallization on the electrode, improve safety and extend battery life. Although this technology still needs some time to test, it is expected that non-flammable lithium batteries will be available soon.

3. Flexible lithium battery

We are all looking forward to the appearance of fully flexible electronic devices, but even though flexible screens have made considerable progress, batteries are still a problem. LG recently showed an OLED screen that can be fully curled. The screen, circuit and battery are also flexible. This is the closest flexible electronic device we have seen in science fiction movies.

In addition, a Chinese Taiwanese company has also announced the start of production of flexible ceramic polymer lithium batteries, with extremely safe characteristics. Although the battery capacity may not be ideal, it is very suitable for wearable devices and is expected to be launched in the market this year.

4. Lithium sulfur and lithium air battery

Two other promising new types of lithium batteries are lithium-sulfur and lithium-air batteries. The characteristic of the former is that it does not require highly volatile solvents, which greatly reduces the risk of fire, even if it is subjected to a large impact; the latter theoretically has a higher energy density, suitable for electric vehicles and other products, but the challenge is that new types of Electrodes and electrolytes. From the current point of view, lithium-sulfur batteries have the advantages of large capacity, low cost and high safety, and are likely to become the mainstream first.

5. Lithium anode

Stanford University scientists recently published a paper that found that ultra-thin carbon clusters can allow lithium metal as an anode, and the power increase is 10 times that of current graphite anodes. However, currently its efficiency can only reach 96%, and it will take time to enter the mass consumer electronics market.

6. Magnesium battery

Magnesium is also a metal element that is expected to be used in the field of batteries. Magnesium ions can carry twice the energy of lithium ions, while having a shorter charging time and stable performance. Magnesium batteries have been commercialized a few years ago, so compared with other new battery materials, they are expected to appear in the consumer field faster.

7. Super capacitor

Supercapacitor is a battery technology that is different from the traditional lithium structure. It can achieve large-capacity and ultra-high-speed charging, but the main obstacle is that the capacitor usually cannot store energy. China’s Tsinghua University, the University of Texas, and the National University of Singapore are all developing supercapacitor batteries with different storage materials, including carbon nanofluids, graphene, etc. However, these technologies still have hidden dangers such as bulkiness and high energy aggregation stability. It is difficult to popularize in the consumer market in the short term.

The above new battery technologies are still in the research and development stage, but it is certain that the improved technologies based on lithium batteries are more likely to be the first to land on the market, and we are expected to use faster, more durable and safe lithium batteries within a few years. The completely different battery types such as super capacitors, magnesium batteries, air batteries, and solar batteries still need time to improve. Once successful, the next revolution of electronic equipment will come. Enjoying fast online games is not a myth.
