Japan's Toshiba company develops a new type of lithium-ion battery that can be charged for 6 minutes and has a range of 320 kilometers, which can be charged and discharged 5000 times

Current mainstream electric vehicles, with support for fast charging, still need 1, 2 hours to fully charge, not to mention slow charging takes 7 or 8 hours.

Current mainstream electric vehicles, when fast charging is supported, it takes 1 or 2 hours to fully charge, not to mention that slow charging takes 7 or 8 hours Up. In order to improve the cruising range while shortening the charging time, major car companies and battery companies are painstakingly researching and breaking through technical problems.

Toshiba Corporation of Japan recently announced that after research and development, the company has developed a new type of lithium-ion battery that can be quickly charged and has an ultra-long life. How fast is it? When used in a small electric car, it can travel 320 kilometers in 6 minutes, and it only takes one song, which is equivalent to the refueling time of a petrol car. How long is the battery life? Even the lithium iron phosphate battery with ultra-high cycle life can only be charged and discharged 2000 times, but the lithium-ion battery developed by the company can maintain more than 90% of the battery capacity even if it is repeatedly charged and discharged 5000 times. In other words, in theory, even if the battery is charged once a day, the battery will only lose 10% of its capacity after 13 years of use.

The reason why this battery has such a powerful operation is attributed to the company's rare metal 'niobium' used in the anode material. 'Niobium' can be used in the steel industry, aerospace industry, electronics industry and other fields because of its unique properties. Of course, there is always a gap between theory and practice. The actual performance of this lithium battery needs to be actually used to know. It is reported that the company strives to achieve mass production in the first half of 2020. By then, you can experience the charging for 6 minutes and driving 320. Kilometers of fun too.

As early as last year, the Wang Chaoyang team of Pennsylvania State University in the United States overcame the technical problem of 10-minute fast charging of power lithium batteries, which was adopted and promoted by the United States Department of Energy. In the future, as the cost-effectiveness of electric vehicles becomes higher and higher, the problem of slow charging will also be solved, and electric vehicles will open up a new road different from fuel vehicles.
