Lithium batteries or will face obsolescence?

In recent years, more and more new energy vehicles have entered people's lives. According to relevant data, by the end of 2020, the number of new energy vehicles in the country has reached 4.92 million, accounting for 1.75% of the total number of vehicles, an increase of 1.11 million vehicles from 2019, an increase of 29.18%. In addition, the increment of new energy vehicles has exceeded 1 million for three consecutive years, and is showing a trend of sustained high-speed growth. It can be seen that the development trend of this industry is very good.

As everyone knows, new energy vehicles use on-board lithium batteries as driving power, and the battery capacity directly affects the car’s endurance. Therefore, for people who want to buy new energy vehicles, they will also pay special attention to the pros and cons of the battery when purchasing.

Lithium batteries must be familiar to everyone. They can be seen everywhere in our daily lives, such as batteries for toys and batteries for motorcycles. Currently, lithium batteries have also been applied to new energy vehicles. However, the disadvantages of lithium batteries themselves have also caused concerns among users of new energy vehicles.

For example, the life of lithium batteries is short, which leads to poor endurance of the car; it is easy to age, which increases the cost of the car; more deadly, lithium batteries are easy to use. Explosion, safety hazards, etc. These shortcomings of lithium batteries all point the finger at the development of more efficient and safe power batteries. For these problems, new energy automobile companies and battery research and development companies are also actively responding.

Super battery comes out, it only takes 15 seconds to fully charge.

In September 2020, the foreign Skeleton company and The Karlsruhe Institute of Technology has jointly launched a graphene battery. This battery has a charge and discharge efficiency 1,000 times faster than ordinary batteries. It takes only 15 seconds to fully charge, and it is not easy to age, and its capacity has also been improved. It is known as super battery. At present, the company has reached a 1 billion euro cooperation with a leading automobile company on this technology, and the mass production of new energy vehicles loaded with super batteries can be realized in the next three years.

Slightly earlier than them, in July 2020, China launched a graphene battery technology that can improve the battery performance of new energy vehicles. It is the GAC Group that developed this technology. . In addition, in December 2020, GAC Group announced that it will conduct real vehicle tests in the near future and launch it on the market smoothly. Although the research and development speed of GAC Group is relatively fast, compared with foreign technologies, the 'hard power' of GAC Group's graphene technology is a bit worse. It takes 8 minutes to charge 80% of the electricity, and it can reach a maximum of 300 kilometers.

In short, the advent of super batteries is expected to greatly improve the endurance and charging efficiency of new energy vehicles, and to a large extent make up for the shortcomings of lithium batteries.

A variety of high-efficiency batteries may be launched

The introduction of super batteries provides a solution to the power problem of electric vehicles. Kind of programs. However, the super battery is not omnipotent. There are still controversial voices regarding its use. This shows that it may have shortcomings. Therefore, a variety of options will also appear in the battery market. In 2021, a variety of high-efficiency batteries will also be launched on the market in an attempt to occupy the power battery market.

On January 9, 2021, NIO Group released a 150kWh solid-state battery, which has a battery life of 1,000 kilometers and improved safety performance. It is planned for the fourth quarter of 2022. Deliver to the market. On January 13, SAIC Zhiji Automobile announced that it has cooperated with CATL to launch a 'silicon-based lithium supplement' battery, which will have a maximum cruising range of more than 1,000 kilometers. On January 16, the chairman of CATL, Zeng Yuqun, revealed to the media that CATL is developing BEV battery packs with a cruising range of more than 1,000 kilometers, a full charge of only 10 minutes, and a 16-year service life of 2 million kilometers.

Lithium batteries have been eliminated?

To sum up, it can be seen that the 'dominant' status of lithium batteries is at stake. In addition to the shortcomings of lithium batteries being effectively compensated by rising stars, what 'shakes' the market position of lithium batteries is also the issue of its important material-lithium resource storage. Lithium is a non-renewable resource, and it will be used up. Therefore, when the lithium resource is exhausted, the lithium battery will automatically withdraw from the market stage.

So, lithium batteries will be eliminated?

For now, lithium batteries will not be eliminated so quickly in the short term. Because in daily life, our demand for lithium batteries is huge. It is reported that in 2019, China's output of lithium batteries has reached 15.722 billion, and the scale of the lithium battery industry has exceeded 200 billion.

The mobile phones, laptops, electric bicycles, electric cars, power tools, digital cameras and other electronic products and equipment we often use also use lithium batteries as operating power. . Moreover, according to relevant surveys, as the scale of my country's new energy vehicles expands, it is expected that the demand for lithium-ion batteries for electric vehicles in my country will further increase in the future.

Therefore, although there are many unfavorable factors in the bad news of lithium batteries, we still need it in the short term.
