The electric car has been charged for more than ten hours, but still dare not turn on the air conditioner for high speed? The "slow charging" pain point that plagues new energy owners is expected to be solved. According to the American popular science magazine Discovery, a paper published in Joule, an American energy academic magazine, said that the new battery invented by researchers at the University of Pennsylvania in the United States can charge the electric vehicle once in 10 minute, making the electric vehicle travel 320 kilometers, which is equivalent to the efficiency of ordinary cars.

The researchers stressed that this technology can quickly heat the battery to 60℃ during charging and then cool it to room temperature. Under normal circumstances, severe temperature fluctuations will cause damage to lithium-ion batteries, but the special film made of nickel can protect the batteries from damage and charge them quickly without affecting their life.

The research shows that this fast charging process can be carried out on the same battery 1700 times.

How to make the batteries of electric vehicles charge faster, last longer and have longer cruising range is a key issue that Tesla and other industry giants have invested heavily in research. According to Discovery, Tesla sponsored the research team of Dalhousie University in Canada to develop a "super battery" in September, with the goal of making the battery life run 6.5438+0.6 million kilometers. Discovery believes that with the continuous development of technology, "10 minute charging station" is expected to be popularized in a few years.
