Smartphones have made great progress in recent years. The more powerful processors, graphics cards, and ultra-clear flexible screens are all incredible. However, the development of cell phone battery technology is slow, and we still have to endure one charge a day. Although we have always been concerned about the development of new material batteries, in fact, the lithium battery technology is still the most likely to achieve a breakthrough in the near future. Below, we will take a look at the development of the next generation of battery technology.
The improved form of lithium batteries is 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 breakthroughs.
1. Non-flammable components
First of all, the safety of lithium batteries is the problem that people most want to solve. Scientists have discovered that an organic solvent called PFPE is more stable, can reduce the influence of crystallization on the electrodes, improve safety and prolong battery life. Although this technology still needs some time to test, it is expected that lithium batteries that will soon be inflammable will be available.
2. Faster charging speed
The R&D team of Nangyang University of Technology has developed a new type of lithium battery. The idea is not the same as other technologies. It is not to increase capacity but to charge time. In just two minutes, you can quickly fill 70% of your battery and charge more than 10,000 times. This technology uses titanium dioxide instead of graphite as an anode material, and Qualcomm also uses a better control chip to achieve a more stable charging effect.
3. Lithium anode
Scientists at Stanford University have recently published a paper and found that ultra-thin carbon can allow lithium metal as the anode, and the power increase is 10 times that of current graphite anodes. However, the current efficiency is only 96%, and it will take time to enter the consumer electronics market.
4. Flexible lithium battery
We all very much look forward to the emergence of fully flexible electronic devices, but even if the flexible screen has achieved not much progress, the battery is still a problem. LG demonstrated a fully-curved OLED screen with bendable screens, circuitry, and batteries.
5. Lithium and lithium air batteries
The other two promising new types of lithium batteries are lithium-sulfur and lithium-air batteries. The former’s characteristic is that it does not require highly volatile solvents, which greatly reduces the potential for fire hazards; the latter has a theoretically higher energy density and is suitable for electric cars and other products, but the challenge is the need for 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 security, and are likely to become the mainstream in the first place.
6. Super capacitor
The supercapacitor is a battery technology that is different from the lithium structure and can realize large-capacity and ultra-high-speed charging, but the main obstacle is that the capacitor cannot normally store energy.
7. Magnesium battery
Magnesium is also a metal element that is expected to be applied in the field of batteries. Magnesium ions can carry twice the energy of lithium ions, while having shorter charging time and stable performance. The magnesium battery has been commercialized several years ago, so it is expected to appear faster in the consumer market than other new battery materials.
