Analyse der zukünftigen Verbesserung der Lithiumbatterietechnologie - Lithium-Ionen-Batterieausrüstung
31. Januar 2023
In case of short circuit and overheating, lithium battery is very easy to explode out of control, which is why we advocate users to use original battery, charger and data cable to prevent short circuit of lithium battery.
Smart phones have made considerable progress in recent years. The more powerful processors, graphics cards, ultra-clear and even flexible screens are impressive. However, the breakthrough in battery technology is slow, and we still have to endure about a day's endurance. Although we have been paying attention to the development of new material batteries, in fact, lithium battery technology is the most likely breakthrough in the near future. Next, let's take a look at the development of next-generation battery technology.
What is a lithium battery?
Lithium battery is a non-aqueous electrolyte solution battery using lithium metal or lithium alloy as anode material. Compared with the previous Ni-MH battery, it has greater capacity, better stability and repeated charge-discharge characteristics. After years of development, it has been quite mature. Almost all consumer-grade lithium batteries are made of anode graphite at present. As for the disadvantages, through the news reports of frequent fire and explosion, we have also learned that lithium batteries are very easy to explode out of control in case of short circuit and overheating. This is why we advocate users to use original batteries, chargers and data cables to prevent short circuit of lithium batteries.(Lithium - Ion Battery Equipment)
Future improvement forms
The improvement forms of lithium battery are diversified, but the direction is basically based on better safety, charging speed, flexible form and performance. Let's look at several new technologies that are expected to make breakthroughs.
1. Non-inflammable components
First of all, the safety of lithium batteries is the most important problem that people want to solve. Scientists have found that an organic solvent called PFPE is more stable, which can reduce the impact of crystallization on the electrode, improve the safety and prolong the battery life. Although this technology will still take some time to test, it is expected that nonflammable lithium batteries will be available soon.
2. Faster charging speed
The research and development team of Nangyang University of Science and Technology has developed a new type of lithium battery. The idea is different from other technologies. It is not to improve the capacity, but to charge time. In just two minutes, it can quickly fill 70% of the battery and charge more than 10000 times. This technology uses titanium dioxide instead of graphite as anode material, and Qualcomm also uses better control chips to achieve more stable charging effect. This technology is characterized by low cost and is very suitable for mobile products and electronic automobile industry.
3. Lithium anode
Recently, scientists from Stanford University published a paper that found that ultra-thin carbon clusters can allow lithium metal as anode, and the electric capacity is 10 times higher than the current graphite anode. However, at present, its efficiency can only reach 96%, and it will take time to enter the mass electronic consumer market.
4. Flexible lithium battery
We all look forward to the emergence of fully flexible electronic devices, but even though flexible screens have made considerable progress, batteries are still a problem. LG recently showed a fully crimpable OLED screen. The screen, circuit and battery are also bendable. This is the closest flexible electronic device we have seen in science fiction movies.
In addition, a Chinese company also announced recently that it began to produce flexible ceramic polymer lithium battery, which has 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.
5. Lithium sulfur and lithium air battery
The other two promising new types of lithium batteries are lithium sulfur and lithium air batteries. The former is characterized by no high volatile solvent, which greatly reduces the potential fire hazard, even if it is subject to a large impact; The latter has a higher energy density theoretically and is suitable for electric vehicles and other products, but the challenge is to develop new electrodes and electrolytes. At present, lithium-sulfur batteries have the advantages of large capacity, low cost and high security, and are likely to take the lead in becoming the mainstream.
