As we all know, compared with traditional fuel vehicles, in addition to the anxiety of mileage, the charging time of several hours at every turn has also become a stumbling block on the road to its promotion. Therefore, how to shorten the charging time while increasing the range of the power battery has become the two core areas of the entire electric vehicle industry.

　　As we all know, compared with traditional fuel vehicles, electric vehicles are not only anxious about mileage, and the charging time of several hours has also become a stumbling block on the road to promotion. Therefore, how to shorten the charging time while increasing the range of the power battery has become the two core areas of the entire electric vehicle industry.

　　A few days ago, the US Department of Energy (DOE) announced that it would use US$19 million to support electric vehicle batteries to achieve extremely fast charging. It aims to reduce the cost of battery packs to less than $100 per kilowatt-hour by 2028, increase the driving range to more than 300 miles, and shorten the battery charging time to less than 15 minutes.

　　Among them, the 10-minute ultra-fast charging technology developed by Wang Chaoyang's team at Pennsylvania State University won this plan and was officially adopted and promoted by the US Department of Energy.

　　It is understood that on the basis of the All-Climate-Battery (ACB) technology, the Wang Chaoyang team has overcome the 10-minute fast charging technology and successfully solved the key problem of lithium battery fast charging and battery life. It is worth mentioning that this research result has also realized the rapid charging of 240Wh/kg power battery within 10 minutes, and has more than 1,000 cycles, which is equivalent to a life span of 500,000 kilometers. This technology will become a battery product that supports 350kW-class fast charging stations.

　　As a brand new battery platform, all-climate battery (All-Climate-Battery, ACB) related research results were first published in the journal Nature in 2016. The battery can be operated and quickly charged at a low temperature of -50°C. It not only solves the problem of lithium evolution of lithium batteries, but also increases the cooling capacity of the cell itself by 20 times. It is a new type of battery that is neither cold nor heat resistant, and does not require an external thermal management system.
