Since the country entered the hot and scorching weather, there has been a lot of news about electric vehicle fires. What causes frequent fires in electric vehicles? In life, most of the common mobile phones, notebook computers, electric vehicles, etc. use lithium batteries, and the occurrence of lithium battery explosion and fire is collectively called "thermal runaway." Although the technical level of lithium batteries is getting stronger and stronger today, the failure of batteries cannot be avoided.

What caused the lithium battery to catch fire? Due to the high temperature of the surrounding environment, the stored energy of the battery suddenly runs out due to thermal runaway. At this time, graphene, a "black gold" material with excellent performance, stood up and put a "fireproof clothing" on the lithium battery to effectively reduce the explosion coefficient of the lithium battery.

A university in the United States released a research report on graphene, fully expressing the principle of using graphene to enclose small lithium cobaltate cathode particles in lithium batteries, using oxygen atoms to leak out from the graphene sheet, preventing the battery cathode from releasing oxygen and avoiding release Of oxygen combined with other flammable products inside the battery, thereby reducing the coefficient of fire. People have to sigh: There is actually such an operation!

Today, global research in the field of battery materials has not yet made breakthrough progress, and graphene composite lithium batteries will be the focus of future research. After years of hard work by scientific researchers, experiments have shown that graphene has a certain auxiliary effect on the improvement of battery performance. This provides a new way of thinking for researchers. Looking into the future, graphene battery technology is bound to see new developments and will be used in life scenarios in the future.

The magic material of graphene has a huge effect on humans, but due to limited technical reasons, it has not been able to achieve large-scale applications. If we can achieve technological breakthroughs in the field of graphene composite batteries, it is a boon for humans! In the future, with the development of technology, the excellent performance of graphene has been developed and will be widely used in various scenarios of life. We look forward to this day as soon as possible!
