New development of lithium ion battery technology

In recent years, with the rapid development of mobile electronic technology, more powerful processors, graphics cards, ultra clear and even flexible screens are impressive. Unfortunately, the breakthrough of the battery has been very slow, and we have to endure a day or so of endurance. Although we have been paying attention to the development of new battery materials, in fact, lithium-ion battery technology is most likely to make a breakthrough in a short time. Let's look at the next generation battery technology. Linde forklift parts

We basically use mobile devices. Now lithium-ion batteries or lithium-ion batteries are used. The negative electrode materials of lithium-ion batteries are batteries using lithium metal or gold clutch and non-aqueous electrolyte solution. Compared with Ni MH batteries, which have larger capacity, better stability and repeatability, they have been quite mature after years of development. Now almost all consumption levels of lithium-ion batteries are made of anode graphite. As for the disadvantages, through the frequent fire and explosion reported in the news, we also learned that lithium-ion batteries are easy to explode out of control in the case of short circuit and overheating. This is why we encourage users to use original batteries, chargers and data cables to prevent short circuit of lithium-ion batteries.

1. faster charging

A team from Nanyang University of science and technology has developed a new type of lithium-ion battery, which works differently from other technologies. It only takes two minutes, the charging time can reach 70%, and the charging times can exceed 10000 times. The technology uses titanium dioxide instead of graphite as anode material, and one company has achieved more stable charging by better controlling the chip. This technology has the characteristics of low cost and is very suitable for mobile products and electronic automobile industry.

2. non flammable components

First of all, the safety of lithium-ion batteries is the most concerned issue. Scientists have found that an organic solvent called PFPE is more stable, reducing the impact of crystallization on the electrode, improving safety and prolonging battery life. Although the technology will be tested for some time, non flammable lithium-ion batteries are expected to be available soon.

3. flexible lithium ion battery

We would like to see fully flexible electronic products, but even with the progress of flexible screens, batteries are still a problem. LG recently demonstrated a flexible screen, circuit and battery fully crimped OLED screen, which is the closest screen we have ever seen to the flexible electronic components in science fiction movies.

In addition, a company recently announced the production of flexible ceramic polymer lithium-ion batteries with extremely high safety performance. The battery capacity may not be ideal, but it is ideal for wearable devices, which are expected to be launched this year.

4. lithium sulfur battery and lithium air battery

The other two promising new lithium ion batteries are lithium sulfur batteries and lithium air batteries. The former is characterized by not using highly volatile solvents, which greatly reduces the risk of ignition, even if the impact is large; The latter theoretically has higher energy density and is suitable for products such as electric vehicles, but the challenge lies in the demand for new electrodes and electrolytes. At present, lithium sulfur battery has the advantages of large capacity, low cost and high safety.

5. lithium anode

Scientists published a paper and found that ultra-thin carbon clusters can make lithium used as an anode, which can increase the power of graphite anode by 10 times. But its efficiency is still only 96%, and it will take time to break into the mass consumer market.

6. magnesium battery

Magnesium is also a promising metal for batteries. Magnesium ions carry twice as much energy as lithium ions, with shorter charging time and more stable performance. Magnesium batteries have been commercialized for several years, so they are expected to enter the consumer market faster than other new battery materials.

7. super capacitor

Supercapacitors are a battery technology different from traditional lithium-ion batteries because they can be charged at high capacity and high speed. Some famous universities are developing supercapacitor batteries using different storage materials, including carbon nanofluids, graphene, etc. However, these technologies still have the potential of large volume, high energy accumulation and good stability, and are difficult to be popularized in the consumer market in a short time.

All these new battery technologies are still in the development stage, but it is determined that the improved lithium-ion batteries are more likely to be listed first. We expect that there will be lithium-ion batteries with faster charging, more durable and safer in a few years.
