Lithium batteries may 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 China has reached 4.92 million, accounting for 1.75% of the total number of vehicles, an increase of 1.11 million over 2019, or 29.18%. In addition, the growth of new energy vehicles has exceeded 1 million for three consecutive years, showing a trend of sustained and rapid growth, which indicates that the industry has a good development trend.

As we all know, new energy vehicles are driven by vehicles, and the battery capacity directly affects the vehicle's endurance. Therefore, for those who want to buy new energy vehicles, they will pay special attention to the advantages and disadvantages of batteries.

Lithium battery must be familiar to everyone. It can be seen everywhere in our daily life, such as toy battery, electric bicycle battery, etc. At present, lithium batteries have also been applied to new energy vehicles. However, the shortcomings of lithium battery itself have also attracted the attention of new energy vehicle users.

For example, the short life of lithium battery leads to poor vehicle endurance; It is easy to age, which increases the use cost of cars; What is more fatal is that lithium batteries are prone to explosion and have safety problems. These shortcomings all point to the development of more efficient and safe lithium batteries. New energy vehicle enterprises and battery R&D enterprises are also actively responding to these problems.

Super batteries have been developed that can be fully charged in 15 seconds

In September 2020, Skeleton and Karlsruhe Institute of Technology introduced a kind of graphene battery. Its charging and discharging speed is 1000 times that of ordinary batteries. It takes only 15 seconds to fully charge, which is not easy to age, and its capacity has also been improved. The company has signed a 1 billion euro technology transaction with a leading automobile company, which may lead to large-scale production of new energy vehicles equipped with super batteries in the next three years.

Earlier than them, the graphene battery technology developed by GAC Group was launched in China in July 2020 to improve the battery efficiency of new energy vehicles. Moreover, in December 2020, GAC Group announced that it would test the real vehicle and put it into the market smoothly. Although the research and development speed of GAC Group is relatively fast, compared with foreign technologies, the "hard power" of the graphene technology of GAC Group is slightly inferior. 80% of the charging takes 8 minutes, and the maximum driving distance is 300 kilometers.

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

A variety of high-efficiency batteries may be introduced

The advent of super battery provides a solution to the power problem of electric vehicles. However, super batteries are not omnipotent, and their use is controversial. This indicates that it may have some disadvantages. Therefore, the battery market will have many choices. In 2021, the market may introduce various high-efficiency batteries to try to take the lead in the power battery market.

On January 9, 2021, NiO Group released a 150kWh solid state battery with a endurance of more than 1000km and improved safety performance. It plans to deliver to the market in the fourth quarter of 2022. On January 13, SAIC Home Automotive Co., Ltd. announced that it would cooperate with SAIC Group. On January 16, Zeng Yuqun, the chairman of Ningde Times, revealed to the media that Ningde Times is developing BEV battery packs, which will have a range of more than 1000 kilometers, a full charge of 10 minutes, a service life of 16 years and up to 2 million kilometers.

The demise of lithium batteries?

To sum up, the supremacy of lithium batteries is at stake. In addition to the fact that the disadvantages of lithium batteries have been effectively remedied by rising stars, which has "shaken" the market position of lithium batteries, there is also an important material - lithium resource storage. Lithium is a non renewable resource, so when lithium resources are exhausted, lithium batteries will automatically exit the market stage.

So, will lithium batteries die out?

At present, lithium batteries will not be eliminated soon. Because in our daily life, we have a huge demand for lithium batteries. It is reported that in 2019, the output of lithium batteries in China has reached 15.722 billion, and the scale of lithium battery industry has exceeded 200 billion.

The mobile phones, laptops, electric bicycles, electric cars, electric tools, digital cameras and other electronic products and equipment that we often use also use lithium batteries as running power. In addition, according to relevant surveys, with the expansion of the scale of new energy vehicles in China, it is expected that the demand for electric vehicles in China will further increase in the future.

Therefore, despite the adversity, lithium batteries are still needed in the short term.
