At the 2022 China electric vehicle conference forum in March this year, Wu Kai, chief scientist of Ningde times, revealed that the third generation CTP (high efficiency group) technology will be launched in April, which is internally called "Kirin battery". Today, according to the interface news report, Zeng Yuqun, chairman of Ningde times, said at the online performance conference that plans to officially release Kirin battery in the second quarter of this year**
Ningde times previously disclosed that the third generation CTP technology has the characteristics of high speed, non-destructive, safety and high efficiency. It can adapt to lithium iron phosphate and ternary lithium battery systems, and the corresponding energy density reaches more than 160wh / kg and 250wh / kg respectively, continuing to lead the highest level in the industry.
It is reported that at the 2022 China electric vehicle hundred people's meeting forum, Wu Kai stressed that under the same chemical system and the same battery pack size, its capacity can be increased by 13% compared with the 4680 battery launched by Tesla**
4680 battery is Tesla's third-generation cell product. The cell product is cylindrical, "46" represents the cylinder diameter of 46mm, "80" represents the cylinder height of 80mm.
In addition, the layout of Ningde times also includes the "sodium ion" battery route. Last October, Ningde times officially released the sodium ion battery, which has the advantages of high energy density, high rate charging, excellent thermal stability, good low-temperature performance and high integration efficiency**
Charge at room temperature for 15 minutes, and the power can reach more than 80%; In the low temperature environment of - 20 ° C, it also has a discharge retention rate of more than 90%; The system integration efficiency can reach more than 80%.
