Is Japan going to take the lead? A Japanese company has developed a new temperature-resistant lithium battery technology

According to recent reports, Japan's Asahi Kasei Corporation has recently achieved a research result. They have successfully verified a new lithium-ion battery electrolyte technology, which enables the battery to work stably between -40 ℃ and +60 ℃. If this technology is applied to the field of electric vehicles, it will enable electric vehicles to operate in most areas on the earth.

The electrolyte is an indispensable component of the battery. The charging and discharging of the car is achieved by the movement of lithium ions between the positive and negative electrodes, and the electrolyte is the carrier of lithium ions. Without the electrolyte, the lithium ions cannot move.

As a liquid, the electrolyte is very easily affected by temperature. Whether it is high or low temperature, it will weaken the battery performance. Therefore, in-depth research from the perspective of electrolyte is one of the ways to solve the problem of reduced battery life.

The technological achievement of Japan's Asahi Kasei is aimed at lithium iron phosphate (LFP) batteries that are currently widely used in electric vehicles. Because this type of battery does not contain rare metals such as nickel, it is low-cost and widely used, but it is very susceptible to temperature.

By adopting a new electrolyte, the problem of power attenuation of lithium iron phosphate batteries in low and high temperature environments can be solved. Whether it is cold winter or hot summer, electric vehicles can maintain continuous power stability.

Asahi Kasei has already provided technology to battery factories, and it is expected that this technology will be widely used in the field of electric vehicles by 2025. Does it seem that Japan is taking the lead?

In fact, my country has long been studying how to make lithium batteries more "durable".

In 2022, the team led by Tang Yongbing, a researcher at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, completed large-scale mass production. After nearly 10 years of research, they have developed a new lithium-ion battery technology that can be stably used in the range of -70 ℃ ~ +80 ℃, and the range spans 150 ℃. Based on the results, they have also successfully developed new products such as lithium manganese oxide, lithium iron phosphate and ternary batteries.

In the rapidly growing market environment of electric vehicles, technological breakthroughs in the battery field will become more urgent and critical.

In addition to the various types of batteries that have been used, there are also various types of batteries such as sodium-ion batteries, lithium-sulfur batteries, and carbon-lead batteries that are ready to go. Whoever can seize the technological opportunity will rule the world in the future.
